Published on 12 Comments on Is Garlic The Source Of Beneficial Lactobacillus Sakei in Kimchi?

As you may have noticed, I write about the beneficial bacteria Lactobacillus sakei a lot. This is because it has turned out to be a great treatment for both chronic and acute sinusitis for my family and others (see post The One Probiotic That Treats Sinusitis). We originally found it in kimchi (it occurs in the kimchi during normal fermentation), but not all kimchi brands. Kimchi is a mix of vegetables (including typically cabbage) and seasonings, which is then fermented for days or weeks before it is eaten.

Why is L. sakei found in some kimchi, but not all? Which vegetable or spice is needed or important for encouraging L. sakei growth? It turns out it is not the cabbage - which is why L. sakei is not normally found in sauerkraut.

A recent study looking at several kimchi samples found that garlic seems to be important for the development of various Lactobacillus bacteria, of which L. sakei is one. The results mean that raw garlic has very low levels of L. sakei, and it multiplies during kimchi fermentation. Note that as fermentation progresses, the bacterial species composition in the kimchi changes (this is called ecological succession).

Korean studies (here and here) have consistently found L. sakei in many brands of kimchi (especially from about day 14 to about 2 or 2 1/2 months of fermentation), but not all kimchi brands or recipes. L.sakei, of which there are many strains, is so beneficial because it "outcompetes other spoilage- or disease-causing microorganisms" and so prevents them from growing (see post).

Excerpts are from the blog site Microbial Menagerie: MICROBES AT WORK IN YOUR KIMCHI

Cabbage is chopped up into large pieces and soaked in salt water allowing the water to draw out from the cabbage. Other seasonings such as spices, herbs and aromatics are prepared. Ginger, onion, garlic, and chili pepper are commonly used. The seasonings and cabbage are mixed together. Now the kimchi is ready to ferment. The mixture is packed down in a glass container and covered with the brining liquid if needed. The kimchi sits at room temperature for 1-2 days for fermentation to take place....Kimchi does not use a starter culture, but is still able to ferment. Then where do the fermentation microbes come from?

Phylogenetic analysis based on 16S rRNA sequencing indicates that the kimchi microbiome is dominated by lactic acid bacteria (LAB) of the genus Leuconostoc, Lactobacillus, and Weissella. Kimchi relies on the native microbes of the ingredients. That is, the microbes naturally found on the ingredients. Because of this, there may be wide variations in the taste and texture of the final kimchi product depending on the source of the ingredients. In fact, a research group from Chung-Ang University acquired the same ingredients from different markets and sampled the bacterial communities within each of the ingredients. The group found a wide variability in the same ingredient when it was bought from different markets. Surprisingly, the cabbage was not the primary source of LAB. Instead, Lactic acid bacteria was found in high abundance in the garlic samples. 

Note that Lactobacillus sakei is an example of a lactic acid bacteria. More study details from  the Journal of Food Science: Source Tracking and Succession of Kimchi Lactic Acid Bacteria during Fermentation.

This study aimed at evaluating raw materials as potential lactic acid bacteria (LAB) sources for kimchi fermentation and investigating LAB successions during fermentation. The bacterial abundances and communities of five different sets of raw materials were investigated using plate-counting and pyrosequencing. LAB were found to be highly abundant in all garlic samples, suggesting that garlic may be a major LAB source for kimchi fermentation. LAB were observed in three and two out of five ginger and leek samples, respectively, indicating that they can also be potential important LAB sources. LAB were identified in only one cabbage sample with low abundance, suggesting that cabbage may not be an important LAB source.

Bacterial successions during fermentation in the five kimchi samples were investigated by community analysis using pyrosequencing. LAB communities in initial kimchi were similar to the combined LAB communities of individual raw materials, suggesting that kimchi LAB were derived from their raw materials. LAB community analyses showed that species in the genera Leuconostoc, Lactobacillus, and Weissella were key players in kimchi fermentation, but their successions during fermentation varied with the species, indicating that members of the key genera may have different acid tolerance or growth competitiveness depending on their respective species.

Although W. koreensis, Leu. mesenteroides, and Lb. sakei were not detected in the raw materials of kimchi samples D and E (indicating their very low abundances in raw materials), they were found to be predominant during the late fermentation period. Several previous studies have also reported that W. koreensis, Leu. mesenteroides, and L. sakei are the predominant kimchi LAB during fermentation (Jeong and others 2013a, 2013b; Jung and others 2011, 2012, 2013a, 2014).

Published on 8 Comments on Antibiotic Use Increases Risk of Developing Chronic Sinusitis

Image result for antibiotics Yes, of course this makes sense!.... Many rounds of antibiotics have an effect not just in one area of the body, but kill off both good and bad bacteria in many areas of the human body. The researchers in this study found that taking antibiotics for a reason OTHER THAN SINUSITIS was associated with an increased risk of developing chronic sinusitis (as compared to those people not receiving antibiotics).

Use of antibiotics more than doubles the odds of developing chronic sinusitis without nasal polyps. And this effect lasted for at least 2 years.

Other research has already associated antibiotic use with "decreased microbial diversity" in our microbiome  and with "opportunistic infections" such as Candida albicans and Clostridium difficile. Diseases such as Crohn's disease and diabetes are also linked to antibiotic use. In other words, when there is a disturbance in the microbiome (e.g.from antibiotics) and the community of microbes becomes "out of whack", then pathogenic bacteria are "enriched" (increase) and can dominate.

This study lumped together chronic sinusitis without nasal polyps (CRSsNP) and chronic sinusitis with nasal polyps (CRSwNP), but when the 2 groups are separated out, then antibiotic use was mainly associated with chronic sinusitis without polyps. It appeared that antibiotic exposure did not significantly impact the odds of developing chronic sinusitis with nasal polyps.

The researchers write: "This effect was primarily driven by the CRSsNP subgroup, which also supports the evolving concept of CRSwNP (chronic sinusitis with nasal polyps) as a disease of primary inflammation rather than infection. Despite this, we elected to analyze the CRS (chronic rhinosinusitis) group as a whole because the precise relationship between CRS with and without nasal polyps remains incompletely understood, and it is possible that a proportion of the CRSsNP patients could go on to develop nasal polyps over time."

Which makes me wonder, will giving beneficial bacteria (such as Lactobacillus sakei) to those who have chronic sinusitis with nasal polyps show the same improvement in symptoms as those people without nasal polyps? Or do 2 treatments have to occur at once: something to lower the inflammation (which may be the reason for the nasal polyps) and also beneficial microbes to treat the bacterial imbalance of sinusitis? We just don't know yet. Note that CRS = chronic rhinosinusitis (commonly called chronic sinusitis). Research by A.Z. Maxfield et al from The Laryngoscope :

General antibiotic exposure is associated with increased risk of developing chronic rhinosinusitis 

Antibiotic use and chronic rhinosinusitis (CRS) have been independently associated with microbiome diversity depletion and opportunistic infections. This study was undertaken to investigate whether antibiotic use may be an unrecognized risk factor for developing CRS. Case-control study of 1,162 patients referred to a tertiary sinus center for a range of sinonasal disorders.

Patients diagnosed with CRS according to established consensus criteria (n = 410) were assigned to the case group (273 without nasal polyps [CRSsNP], 137 with nasal polyps [CRSwNP]). Patients with all other diagnoses (n = 752) were assigned to the control group. Chronic rhinosinusitis disease severity was determined using a validated quality of life (QOL) instrument. The class, diagnosis, and timing of previous nonsinusitis-related antibiotic exposures were recorded.

Antibiotic use significantly increased the odds of developing CRSsNP  as compared to nonusers. Antibiotic exposure was significantly associated with worse CRS QOL {Quality of Life} scores over at least the subsequent 2 years. These findings were confirmed by the administrative data review. Use of antibiotics more than doubles the odds of developing CRSsNP and is associated with a worse QOL for at least 2 years following exposure. These findings expose an unrecognized and concerning consequence of general antibiotic use.

Antibiotic use and chronic rhinosinusitis (CRS) have been independently associated with microbiome diversity depletion and opportunistic infections. This study was undertaken to investigate whether antibiotic use may be an unrecognized risk factor for developing CRS.....Antibiotics have also been associated with significant adverse side effects. It has long been recognized that antibiotic use may lead to increased susceptibility to secondary mucosal infections from pathogens including Candida albicans and Clostridium difficile.  Recent studies on the concept of mucosal microbial dysbiosis have suggested that these infections arise as a result of antibiotic induced depletion of the diverse commensal microbial assemblage, which enables the proliferation of pathogenic species.

Chronic rhinosinusitis (CRS) is defined....as having greater than 12 weeks of sinonasal symptoms, along with at least one objective measure of infection or inflammation by nasal endoscopy or radiographic imaging....However the distinct lack of long-term disease resolution following antimicrobial therapy and in some cases surgery, suggests that additional factors are likely involved. Through these studies, CRS with nasal polyps (CRSwNP) has been recognized as an inflammatory subtype characterized by eosinophilic inflammation and a T-helper cell type 2 immunologic profile. Although CRSwNP lacks the features of a classic infectious process, the precise role of bacteria and their byproducts in the promotion of nasal polyp-related inflammation remains unclear.

Recent findings from culture independent investigations of the sinonasal microbiome have offered new insights into the pathogenesis of CRS. These studies have suggested that a decreased microbial diversity exists in CRS patients as compared to healthy controls with a selective enrichment of pathogenic species. Furthermore, some studies have shown that antibiotic exposure may be a risk factor associated with this loss of biodiversity,  echoing the findings seen in postantibiotic C. difficile infections.  Although systemic antibiotics have long been a mainstay of therapy for CRS, these findings lead inexorably to the paradoxical hypothesis that antibiotic exposure may, in fact, promote its onset.

We performed a....case control study of 1,574 patients referred to the Massachusetts Eye and Ear Infirmary Sinus Center in 2014 with symptoms of presumed sinonasal disease.... Inclusion criteria included all antibotic naive patients, and all antibiotic exposed patients for whom antibiotic use was for nonsinonasal-related infections. Among the antibiotic exposed group, only patients who used antibiotics for nonsinonasal-related infections prior to the onset of symptoms of CRS (within the case group) were enrolled in the study.....The case group was further substratified into CRS patients without nasal polyps (CRSsNP, n =273) and with nasal polyps (CRSwNP, n =137) based on the presence of nasal polyps on sinonasal endoscopy.

Among the case patients, 56.34% reported a previous nonsinus-related antibiotic exposure as compared to 42.02% of control patients. Antibiotic use significantly increased the odds of developing both CRSsNP and any form of CRS as compared to nonusers. This odds ratio was similar even when excluding patients who were treated for upper aerodigestive infections. In contrast, antibiotic exposure did not significantly impact the odds of developing CRSwNP. The percent of patients with any form of CRS and CRSsNP only, which was attributable to a previous exposure to antibiotics, was 24.69%  and 33.70%, respectively. In both the case and control groups, the most common class of antibiotic patients received was a penicillin (52.63% vs. 45.77%), and the most common reported reason for antibiotic prescription was the diagnosis of pharyngitis(18.06% vs. 16.67%).

Among the CRS patients (i.e., case group), the use of antibiotics was significantly associated with worse QOL scores as compared to antibiotic-naıve CRS patients. The effect on QOL was enduring because patients who used antibiotics at least 2 years prior to the development of CRS (36.81%) had similar disease severity scores as compared to those with more recent exposures. There was no significant difference in QOL score among patients using different antibiotic classes and among patients with different underlying reasons for antibiotic use.

The human microbiome project has provided new insights into the distribution and abundance of bacterial species in both health and disease. Opportunistic pathogens, as defined by the pathosystems resource integration center, were found nearly ubiquitously in the nares of healthy subjects, albeit at relatively low abundance. Additional studies of the normal nasal cavity found an inverse correlation between the prevalence of Firmicutes such as S. aureus and benign commensal organisms, suggesting a homestatic antagonism between potential pathogens and the remainder of the healthy microbial assemblage. Extrapolation of this concept would therefore predict that events resulting in a perturbation or loss of the commensal microbial community would enable proliferation of pathogenic species, resulting in the disease phenotype. This prediction has borne out in several studies of the sinonasal microbiome in patients with CRS. Feazel et al. found a decreased number of bacterial types and an overabundance of S. aureus among CRS patients as compared to controls. Antibiotic exposure was one of the most significant clinical factors driving this effect. Similar findings were published by Choi et al. and Abreu et al.... Although literature regarding the sinonasal microbiome in health and disease remains nascent, it has provided some limited clues that antibiotics may lead to a reduction of sinonasal microbial biodiversity, which in turn may be a significant feature of CRS.

Our results demonstrate that exposure to antibiotics is a significant risk factor for the development of CRS and accounts for approximately 25% of the disease burden in our study population. These findings harmonize with the predictions of the nascent literature on the sinonasal microbiome. This effect was primarily driven by the CRSsNP subgroup, which also supports the evolving concept of CRSwNP as a disease of primary inflammation rather than infection. Despite this, we elected to analyze the CRS group as a whole because the precise relationship between CRS with and without nasal polyps remains incompletely understood, and it is possible that a proportion of the CRSsNP patients could go on to develop nasal polyps over time.....

One unexpected outcome of our study was that a large percentage of exposures preceeded the onset of the diagnosis of sinusitis by more than 2 years. This indicates that, regardless of the mechanism, the sequelae of antibiotic use may endure much longer then previously thought....The impact of antibiotics on promoting bacterial resistance, and the development of mucosal infections from pathogens such as C. difficile and C. albicans, has been well established. This study demonstrates that antibiotics also significantly increase the risk of developing CRS, an effect that is driven primarily by CRS patients who do not have nasal polyps. Furthermore, premorbid antibiotic use could account for approximately 25% of our patients who developed CRS, and exposure conferred a worse disease-specific quality of life.

Published on Leave a comment on Biofilms In Chronic Sinusitis

An interesting study (published in September 2015) looked at how prevalent biofilms are in the sinuses of people with chronic sinusitis (with or without nasal polyps) as compared to healthy people (without chronic sinusitis). Biofilms are communities of bacteria sticking to one another and coated with a protective slime. The researchers found that the most biofilms were found in people with chronic sinusitis who also had nasal polyps (97.1%) , followed by those with chronic sinusitis without nasal polyps (81.5%), and the least in the control group of healthy patients (56%). They felt that the biofilms contributed to or had a role in chronic sinusitis. But note that the majority of people in all groups had biofilms.

Unfortunately nowhere in the study was there an analysis of the bacteria making up the biofilms. Are the bacteria in the biofilms different in the healthy people versus those with chronic sinusitis? The general assumption is that biofilms are formed from pathogenic (bad) bacteria such as Staphylococcus aureus, but it is known that beneficial bacteria such as Lactobaccillus plantarum and Lactobacillus reuteri can also form biofilms. One study concluded that: "L. reuteri biofilms secreted factors that confer specific health benefits such as immunomodulation and pathogen inhibition." So what was in the biofilms of healthy people (without chronic sinusitis)? Were the biofilms in healthy sinuses made up of protective beneficial bacteria or pathogenic bacteria that were kept in check by other "beneficial" microbes (which can be bacteria, fungi, viruses, etc) in the sinus microbiome?

Biofilms are very hard to eradicate, even with antibiotics. The researchers mentioned that "To date many different modalities have been tested, from Manuka honey to ultrasound and surfactant, but none have been shown to be very efficient." However, they did not mention other bacteria (probiotics) as a treatment possibilty in eradicating biofilms in the sinuses. There has been research looking at using probiotics against biofilms elsewhere in the body (such as dental plaque on teeth).

If biofilms from pathogenic bacteria are so pervasive in chronic sinusitis (81.5% to 97.1%), then it appears that some bacteria such as Lactobacillus sakei somehow predominate over them. I am saying this based on the majority of people writing to me saying that L. sakei treated their chronic sinusitis, as well as the experiences of my own 4 family members (at least 3, perhaps all 4 of us probably had biofilms in our sinuses based on the 81.5% to 97.1% numbers in this research). Something to contemplate. From the journal Acta Oto-Laryngologica:

Bacterial biofilms in chronic rhinosinusitis; distribution and prevalence.

Biofilms were more prevalent in patients with CRSwNP [chronic rhinosinusitis with nasal polyps] compared to both CRSsNP [chronic rhinosinusitis without nasal polyps] and controls [healthy people], and also on the ethmoid bulla compared to the middle turbinate, supporting a biofilm-related pathogenesis of CRSwNP....This study comprised 27 patients with CRSsNP, 34 patients with CRSwNP, and 25 controls.

Chronic rhinosinusitis (CRS) is today understood as a multifaceted group of diseases. The most established differentiation is between CRS with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP)....Patients with CRSwNP have the worst quality-of-life scores, and they have frequent recurrences of their symptoms after surgery.

The pathophysiology of nasal polyps is poorly understood. Bacterial infection, in the form of biofilms, is proposed as a major drive behind the inflammation in CRS. Bacterial biofilms is identified as the agent behind an ever increasing number of chronic infectious diseases, ranging from endocarditis to dental caries. Bacterial biofilms are communities of bacteria in their sessile form, and can be extremely difficult to eradicate with conventional antibiotic therapy.

The total number of patients in the CRS group was 61, 23 females and 38 males, and median age was 40 years....Bacterial biofilms were detected in 97.1% of patients with CRSwNP, 81.5% of patients with CRSsNP, and 56% of controls. Patients with CRSwNP had highly significantly increased prevalence of biofilms compared to controls....The prevalence of biofilms in different anatomical locations within the nasal cavity differed....Biofilms were detected in 79.6% of the samples from the ethmoid bulla, 70.9% of the samples from the uncinated process, and 62.0% of the samples from the middle turbinate.

In this study a significantly increased prevalence of biofilms were found in patients with CRSwNP compared to controls, but also compared to CRSsNP. Indeed only one of the patients with CRSwNP was biofilm negative. This indicates a role for biofilms in the pathogenesis of CRS, but specifically in CRSwNP.

The pathophysiological mechanisms underlying nasal polyps are still poorly understood. Biofilms are shown to be heterogeneous and can be composed of both bacteria and fungi. Staphylococcus Aureus feature prominently in most biofilms found in the sinonasal cavity, being isolated in 50% of the samples. and can possibly facilitate co-colonization with fungi....Bacteria in a biofilm are shown to have up to a 1000-fold increased resistance to antibiotics compared to planktonic bacteria. These features of biofilms make them notoriously hard to eradicate.... In the setting of CRS we have the opportunity of direct local treatment which gives us a greater range of potential treatment options. To date many different modalities have been tested, from Manuka honey to ultrasound and surfactant, but none have been shown to be very efficient....In regards to nasal polyps, further studies are needed to investigate why some patients with biofilms develop nasal polyps while others do not.

Biofilms thrive in moist areas without too much turbulence, conditions found deep in the middle meatus. This may also explain why there were a higher number of biofilm positive CRSwNP patients, as regular nasal polyps originate in the ethmoid....In the opinion of the authors the findings in this article suggest a role for biofilms in CRSwNP.

Published on 4 Comments on Three Years of Sinusitis Treatment Success

It's now 3 years being free of chronic sinusitis and off all antibiotics! Three amazing years since I started using easy do-it-yourself sinusitis treatments containing the probiotic (beneficial bacteria) Lactobacillus sakei. My sinuses feel great! And yes, it still feels miraculous.

After reading the original ground-breaking research on sinusitis done by Abreu et al (2012), it led to finding and trying L. sakei as a sinusitis treatment. Of course, there is an entire community of microbes that live in healthy sinuses (the sinus microbiome), but L. sakei seems to be a key one for sinus health.

I just updated the post The One Probiotic That Treats Sinusitis (originally posted January 2015) using my family's experiences (lots of self-experimentation!) and all the information that people have sent me. The post has a list of brands and products with L. sakei, as well as information about some other promising bacteria. Thank you so much! [For latest see: The Best Probiotic For Sinus Infections]

Thank you all who have written to me  - whether publicly or privately. Please keep writing and tell me what has worked or hasn't worked for you as a sinusitis treatment. If you find another bacteria or microbe or product that works for you - please let me know. It all adds to the sinusitis treatment knowledge base. I will keep posting updates. 

(NOTE: I wrote our background story - Sinusitis Treatment Story back in December 2013, and there is also a  Sinusitis Treatment Summary page with the various treatment methods.

Published on 6 Comments on Update on Sinusitis Treatment

[UPDATE:  I added an Oct. 2018 update to the post The One Probiotic That Treats Sinusitis, which was originally posted in January 2015.]  Updates incorporate the latest information about treatments and products with Lactobacillus sakei  (kimchi brands, the probiotic Lacto Sinus , the sausage starter culture Bactoferm F-RM-52, etc.). According to research by Abreu et al (2012), Lactobacillus sakei is a bacteria or probiotic (beneficial bacteria) that chronic sinusitis sufferers lack and which treats chronic sinusitis. Chronic sinusitis sufferers also don't have the bacteria diversity in the sinuses that healthy people have.

Many thanks to those who have written to me about their experiences with L. sakei products and sinusitis treatment.  Please keep the updates, results, and progress reports coming. If you have had success with other kimchi brands, please let me know so that I can add it to the list. And I also want to hear if other probiotics work or don't work, or if you have found other sources of Lactobacillus sakei or new ways to use L. sakei. It all adds to the knowledge base which I will continue to update.  You can Comment after posts, the Sinus Treatment Summary page, on the CONTACT page, or write me privately (see CONTACT page).

It is now over 2 1/2 years since my family (4 people) successfully treated ourselves with Lactobacillu sakei for chronic sinusitis and acute sinusitis. We feel great! With each passing year we can tell that our sinus microbial community is bettter, and levels of inflammation are down. As a consequence, we are getting fewer colds or viruses than ever. And best of all - no antibiotics taken in over 2 1/2 years! Yes, Lactobacillus sakei absolutely works as a treatment for sinusitis.

Published on 2 Comments on Two Years (and Counting) Without Sinusitis

It is now 104 weeks being free of chronic sinusitis and off all antibiotics! Two full years since I started my easy do-it-yourself sinusitis treatment! And my sinuses feel great! I would never ever have thought such a thing was possible several years ago. Thanks to the probiotic (beneficial bacteria) Lactobacillus sakei I got my life back. Yes, I know I'm gushing...

After reading the original ground-breaking research on sinusitis done by Abreu et al (2012), it led to finding and trying L. sakei as a sinusitis treatment. Of course, there is an entire community of microbes that live in healthy sinuses (the sinus microbiome), but L. sakei seems to be a key one for sinus health. As you may have guessed, the name of this web-site Lacto Bacto is in homage to the bacteria Lactobacillus sakei.

Thank you all who have written to me  - whether publicly or privately. Please keep writing because it is adding to the sinusitis treatment knowledge base. I will keep posting updates.

I will be trying to find more sources of L. sakei this year and also look for other microbes that help treat sinusitis. And the foods or products that they're in. As of today, my family (all 4 members) have successfully used live kimchi and even sausage starter culture (both containing L. sakei) to treat both acute and chronic sinusitis these past 2 years. Based on our experiences and those of others, finding live L. sakei in kimchi (not all brands have L. sakei in it) and other products can be tricky, but when the product has live L. sakei in it - the results are absolutely great! We have also learned that L.sakei products should be used sparingly - only as needed.

[NOTE: Since then I've posted a number of posts with sinusitis treatment information. The updated (November 2018) The Best Probiotic For Sinus Infections has products and sources of L. sakei. The Sinusitis Treatment Summary page has treatment methods. And news about a Lactobacillus sakei product which I really like - Lacto Sinus.

Published on 252 Comments on The One Probiotic That Treats Sinusitis

[Please go to updated June 2022 version of this post.]

(Oct. 2018) Probiotics and sinusitis treatment go hand in hand. In the last few years researchers found that one probiotic (beneficial bacteria) that chronic sinusitis sufferers lack and that treats and cures sinusitis is Lactobacillus sakei.  And for many, major improvement may take only days!

The researchers Abreu et al found in their 2012 study that not only do sinusitis sufferers lack L. sakei, they have too much of some other bacteria, and they also don't have the bacteria diversity in their sinuses that healthy people without sinusitis have. In other words, the sinus microbiome (microbial community) is out of whack (dysbiosis). A number of studies since then also found that there is a depletion of some bacterial species, and an increase in "abundance" of other species in those with chronic sinusitis.

Luckily Lactobacillus sakei is found in some foods (such as some brands of live fermented kimchi), some sausage starter cultures (such as B-2), and recently in some probiotic supplements (e.g. Lanto Sinus). One reason it is used in sausage starter cultures is because L. sakei dominates over and inhibits growth of pathogenic bacteria, including Staphylococcus aureus. This post discusses these L. sakei products and other possible probiotic treatments for sinusitis.

Treating sinusitis with beneficial bacteria (rather than with antibiotics, corticosteroid nasal sprays, and surgery) is the future in sinusitis treatment.

BACKGROUND STORY: More than 5 years ago there were no probiotics containing L. sakei. None. So I experimented using a very easy kimchi sinusitis treatment (basically dabbing and smearing kimchi at certain stages of fermentation into my nostrils like a very messy eater) and found that it cured my chronic sinusitis of many years within two weeks. Obviously it contained L. sakei. Then the rest of my family also tried the kimchi treatment and were also quickly cured of chronic sinusitis! It felt miraculous, especially because it was so easy to do.

After 5 years we still feel great! Generally we only need to treat again with a product containing Lactobacillus sakei (we've been using refrigerated Lanto Sinus) after a virus which goes into sinusitis, or if for some other reason we feel like we're sliding into sinusitis. We've improved every year so need to do it less and more minimally.

Because we no longer have chronic sinusitis and can easily treat sinusitis if it occurs with L. sakei, we have NOT taken antibiotics or any other bacteria killing spray or product (such as xylitol) for over 5 years. We do not use cortisone or antihistamine nasal sprays either.

WHEN A TREATMENT WORKS: A number of you have contacted me to report your own progress with various sinusitis treatments. People used terms such as "miraculous", "transformative", and "fabulous" when they had positive results with a product containing L. sakei  -  and many with major improvement happening within a few days. I’ve also heard from a few people of some other beneficial bacteria species that may treat sinusitis.

When a treatment works, then all sinusitis symptoms go away  --sometimes within days, sometimes longer. This includes post nasal drip, sinus headaches, "clogged ears", bad breath, and sinusitis-related coughs. Even tonsil stones! (Please note that trying such products to treat sinusitis is self-experimentation - effects can be positive or negative. One should always be cautious.)

OVERALL RESULTS: The majority of people contacting me with results reported positive results (chronic sinusitis greatly improved or totally gone) from some form of L. sakei treatment. Successes have been reported to me from the USA, Canada, Europe, Australia, New Zealand, and Africa. But since it's from self-experimentation and not a clinical trial, then I don't know the actual percentage of positive results.

Some of the people reporting success have had multiple operations, some currently have deviated septums, some with nasal polyps, and all have had long-standing chronic sinusitis, some for decades. Interestingly,  Lactobacillus sakei works best when it is used only when needed, when there are sinus symptoms. Don't use when feeling healthy.

Those same chronic sinusitis sufferers also reported that the same treatments also worked to treat acute sinusitis or sinus infections. It seems that after colds or viruses may develop acute sinusitis again and need re-treatment (apparently the L. sakei frequently doesn't stay in the sinuses from earlier treatments). However, the sinuses do continue improving over time so fewer and more minimal treatments are needed over the years.

Another very small group reported that other probiotic strains helped, and a minority of people reported that nothing has helped and there could be a variety of reasons for this (see below). Some people reported that one product helped, but not another - whether kimchi or a L. sakei product. It also became clear that L. sakei does not treat seasonal allergies or allergy symptoms.

THREE MAIN PRODUCT CATEGORIES: The main categories of products containing live Lactobacillus sakei are:: kimchi (and some sauerkraut), refrigerated products, and frozen products. Note that at this time the FDA does not allow any probiotics to be sold as a medical treatment – they can only be sold as a supplement.

Using the following products to treat sinusitis is self-experimentation (results are unknown and can vary). Always be cautious when testing a new product. (See Sinusitis Treament Summary page for treatment methods.)

KIMCHI - Many people report that kimchi helped them. One person reported a homemade kimchi worked great (he was finally symptom free after 8 years). A few have even mentioned that kimchi has helped sinusitis with fungal problems.

Kimchi brands that people reported helping their chronic sinusitis: Sunja's Kimchi (mild white kimchi and medium spicy cucumber kimchi), Sinto Gourmet brand kimchi, Mama-O's Premium Kimchi, the white Napa kimchi and cabbage kimchi made by Choi's Kimchi Company (in Portland, Oregon), Farmhouse Culture Kimchi (in California), Ozuke Kimchi (in Colorado), Mother-in-law's Kimchi, in the United Kingdom the brand Mr Kimchi, and in Australia Kehoe's Kitchen white kimchi.

(Not all kimchi brands or types of kimchi within brands contain L. sakei - finding one that has it is due to self-experimentation. The kimchi must be live, and not pasteurized. We found that kimchi may contain L. sakei from about day 14 (or earlier) to about 2 to 2 1/2 months (from the day it's made).

When the kimchi contained L. sakei we felt the same or started feeling better within one or 2 days. If we felt more mucusy over the next 2 days, or the acute sinusitis kept getting worse, than it did not contain L. sakei.) Some researchers feel that it's the garlic in kimchi that encourages L. sakei growth.

SAUERKRAUT - Some people improved with sauerkraut made with garlic. Some researchers feel that it's the garlic in kimchi that encourages L. sakei growth, and sauerkraut typically doesn't contain garlic.

REFRIGERATED LACTOBACILLUS SAKEI PRODUCTS  – A refrigerated L. sakei product specifically meant for the sinuses is now available. The company Lanto Health has introduced a kimchi derived Lactobacillus sakei product called Lanto Sinus - to be used when needed (when there are symptoms). Lanto Sinus  is sold as a dietary supplement, holds up well in the refrigerator, is effective, quick-acting, and easy to use. This high-quality product ships well because it holds up for a while (days) without refrigeration.

People have reported success using it mixed with bottled water (dabbing, smearing, spooning a little in nostrils), or swishing it dry in the mouth. I’ve been a consultant with Lanto Health on this product and have been testing and using this product successfully for over a year (self-experimentation!).

FROZEN LACTOBACILLUS SAKEI PRODUCTS  – The main L. sakei products available in many countries throughout the world are various frozen sausage starter cultures. All L. sakei products needing to be kept frozen are generally reliable and effective for sinusitis treatment. They should only be used when needed. But negatives with all frozen L. sakei products are that they must be kept frozen, they don’t hold up well once the package is opened, and they can easily die off during shipping.

Sausage starter cultures include BACTOFERM F-RM-52 (many countries, made by Chr. Hansen), PRIMAL SK NATUR 50 (Europe, made by Van Hees), and BITEC LS-25 (Europe, made by Frusarum). These starter cultures contain 2 types of bacteria (L. sakei and Staphylococcus carnosus) – little is known about S. carnosus, but it is considered non-pathogenic, and no one has reported negative effects from it. B-2, which is only L. sakei (made by Chr Hansen), is available in New Zealand and some EU countries. The starter culture BACTOFERM  SM 160 (L. sakei, Staphylococcus carnosus and Debaryomyces hansenii) has also been used successfully for chronic sinusitis. But one should be very cautious because while the third bacteria is considered non-pathogenic, is common in food products, is used commercially to make B12 - it is a yeast species (fungi).

Most use a frozen product by dabbing/smearing or spooning a little of the mixture (L. sakei and bottled water) into the nostrils. Sometimes a side effect on the day the product is used is a dry mouth and throat (and they can be very dry when overused - so it's important to use only a little in a treatment). The person who used the nasal aspirator reported a temporary decrease in her sense of smell.

[NOTE: I personally have overuse concerns (too strong a dose) with using L. sakei in a neti pot or nasal syringe, and so have never used any L. sakei product that way. My personal view: let the little suckers travel up to the sinuses on their own. And they do. And I always start first with the most cautious way to see if that works.]

SOME L.SAKEI ISSUES: I still think of L. sakei as fairly fragile – for example, it is killed off by antibiotics, by oxygen, and it only lives a limited amount of time at room temperature. [For ex.: the culture Bactoferm F-RM-52 package says that it dies off in less than 2 weeks at room temperature - therefore store in freezer.] On the other hand, many different Lactobacillus strains live and multiply in our bodies at 98.6 degrees Fahrenheit - so L. sakei can handle warm temperatures just fine for a while.

Note that the L. sakei in any product can also die off during shipping if it takes too long, it’s too hot (e.g. inside hot postal vehicles in extreme heat), or some other reason. Thus we order 2 day shipping (if possible) and hope for the best. (Note: Consider overnight shipping during 100+degree Fahrenheit heat waves. Also, USPS delivers to mailboxes, while UPS typically delivers to the door.)

WHY DOESN'T L. SAKEI WORK FOR SOME PEOPLE? Some possibilities to explain why some people trying various L. sakei products has not resulted in their sinusitis improving is that perhaps some other "keystone species" (a very important microbial species for a normal healthy community) besides L. sakei is  missing in their sinus microbiomes. Or perhaps they have microbes that the L.sakei bacteria cannot overcome.

It is unclear whether the results are different if there are also nasal polyps. Researchers now suspect that those with nasal polyps also have a problem with "primary inflammation". We (modern medicine) know so little about the normal healthy sinus microbiome that there are many unanswered questions.

PROBLEM WITH A PRODUCT SUDDENLY NOT WORKING, OR OVERUSE - Several people reported that a kimchi brand or L. sakei product that originally worked for them suddenly stopped working or not as well, but usually it had been the only product used for a while. There may be a feeling of "imbalance" or on rare occasion some symptoms (e.g. more mucus, sore throat). We think this might be an issue of "too much of certain microbes".

Then we (family members) have found that immediately switching to another product (e.g., from one brand or type of kimchi to another), or from a L. sakei product to kimchi, or swishing an opened capsule (the dry powder) of multi-strain probiotics, or refrigerated L.sakei in the mouth (this last if switching from kimchi)  has corrected the situation for us. (Finding what works is self-experimentation, and varies from time to time.). And weeks later, we can use the original product once again. This is also why we only use a product when needed.

BOTTOM LINE: When feeling good or healthy, stop using the L. sakei product. Use L. sakei products sparingly - only as needed (e.g. when developing sinusitis). Using less is better than more over time – probably due to sinus microbial communities improving over the years. L. sakei seems to be necessary for sinusitis treatment for most people (a keystone bacteria), but there are also other important microbes in the sinuses - a whole community.

OTHER PROBIOTICS MAY OR MAY NOT HAVE BENEFICIAL EFFECTS - Rarely some people have reported that multi- strain probiotics (but they did not contain L. sakei) treated their sinusitis. They mixed the powder in the capsules with water and smeared or dabbed the mixture in the nose, or even used it in a saline rinse (this last was rare). Different brands containing different mixtures of bacteria (Lactobacillus and Bifidobacterium) have been mentioned - but all were refrigerated probiotics - so nothing stands out.

On the other hand, other people (including my family members) reported trying various multi-strain probiotics containing various Lactobacillus and Bifidobacterium species in the nostrils and found it did not help sinusitis. However, we found that when we feel a little “imbalanced” – perhaps a cough or mucusy – then swishing the dry powder from one capsule in the mouth and then swallowing it - frequently results in some improvement (perhaps with a cough).

I have concerns with products that also contain titanium dioxide – this is because it may be in nanoparticle form, and recent studies have raised concerns that the nanoparticles can travel to other organs in the body, and are also inflammatory. So read the ingredients!

STILL UNKNOWN: Some multi-strain probiotics now contain L. sakei, but may be problematic if they don’t need refrigeration (e.g. Multi-strain Probiotic by Innovix Labs). L. sakei products typically die after a few weeks without refrigeration, and die when exposed to oxygen (anaerobic).  So...while the L. sakei may be alive when the product is produced, is it alive weeks or months later at room temperature?

Also, will a multi-strain probiotic containing both L. sakei and S. salivarius K12 (such as Pro-Kids ENT by Hyperbiotics) help or make things worse for those with sinusitis?  S. salivarius K12 has caused problems for some people (scroll down to "Problems With BLIS K12?").

NO EVIDENCE FOR JUST SWALLOWING PROBIOTIC SUPPLEMENTS: Evidence (my family, people writing in, research) so far has been that only directly dabbing/applying probiotics in the nose, or even swishing probiotics in the mouth may help treat sinusitis. I have not found any studies finding that just swallowing a probiotic pill has helped sinusitis (including a 2009 study looking at swallowing L. rhamnosus tablets 2 times daily for 4 weeks).

PROMISING PHAGE THERAPY - Some researchers in the USA and Australia are currently testing phage therapy to see if it could be used as a treatment for chronic sinusitis. A bacteriophage is a virus that infects bacteria, and the name literally means "bacteria eater". Phage therapy is the therapeutic use of bacteriophages to treat bacterial infections. See the June 3, 2016 post Phage Therapy May Help Sinusitis Sufferers for more information.

The authors of one study I posted said that they had found evidence for people having "virus-like particles" in their sinuses, which they thought were bacteriophages.

SNOT TRANSPLANTS IN THE FUTURE? – Currently a “snot transplant” study from healthy persons to sinusitis sufferers is going on in Europe to see if it works as a sinusitis treatment. This possibility may work great, but researchers have the same concerns as with fecal microbial transplants (stool transplant) for the gut. For example, are diseases also being transplanted?

PROBLEMS WITH BLIS K12 ? - Some people (and family members) tried the probiotic BLIS K12 bacteria (also known as Streptococcus salivarius BLIS K12), but found it brought on sinusitis-type symptoms. Scientific research finds it to be an immune booster and it lowers the incidence of upper respiratory infections. But not for us - from the first tablet (ate it by slowly dissolving it in the mouth) there were problems - feeling phlegmy and yellow mucus.

Several persons reported similar negative effects with PRO-dental tablets, which also contains BLIS K12. The message here is clear: these specific bacteria did not react well with our sinus and oral bacterial communities. Remember, whenever one introduces new bacteria into the human organism, there can be positive or negative effects.

PLEASE WRITE!  I would really like to hear how you are treating and curing your sinusitis, especially chronic sinusitis. Or even what hasn't worked. It all adds to the knowledge base. Write to me privately, or can comment after any post.

20131201_101300 Several people have recently written to me about kimchi and asked why I originally chose vegan kimchi over kimchi containing a seafood ingredient (typically fish or shrimp sauce) for sinusitis treatment. I have also been asked whether vegan kimchi has enough Lactobacillus sakei bacteria in it as compared to kimchi made with a seafood seasoning. (see Sinusitis Treatment Summary page and/or Sinusitis posts for in-depth discussions of Lactobacillus sakei in successful sinusitis treatment).

Korean kimchi is a fermented food typically made with cabbage and other vegetables and seasonings, and can contain some seafood (perhaps fish or shrimp sauce) as a seasoning, or just be vegan (no seafood ingredients). It can also be made using a starter culture.

These questions arose because Lactobacillus sakei (L.sakei) is commonly found on meat and fish, and plays a role in the fermentation and preservation of meat. L.sakei "outcompetes other spoilage- or disease-causing microorganisms" and so prevents them from growing. Thus it is considered beneficial and is used commercially in lactic acid starter cultures (for example, in making European salami and sausages).

L. sakei was originally isolated from sake or rice wine (thus plant origin), is found in very low levels in some fermented sauerkraut, and according to the studies I looked at, is found during fermentation in most brands of Korean kimchi.

Currently there are over 230 different strains of L.sakei isolated from meat, seafood, or vegetables from all over the world (from S. Chaillou et al 2013 study looking at population genetics of L.sakei). So this bacteria, which is found by using state of the art genetic analysis, turns out to be quite common.

So why did I only use vegan kimchi and only mention vegan kimchi in our Sinusitis Treatment method?

It's because when I first started dabbing kimchi juice in my nose about 1 1/2 years ago, I was in uncharted territory. I was desperate for something with L.sakei in it, and from my reading I found kimchi. However, putting (by dabbing or smearing) a live fermented product in my nostrils was a big unknown. When I first opened some jars, the kimchi juice would bubble and sometimes overflow and run down the sides of the jar. Would the microbes in kimchi harm or benefit me? Obviously I was conducting an experiment with unknown results.

I settled on vegan (no seafood) kimchi because a totally plant-based product sounded safer to me. I wondered what other microbes are in the kimchi with seafood. Could any of them be harmful?  And my choice of vegan kimchi turned out great.

Our experiences with kimchi are that it works amazingly well in treating sinusitis and causes no harm (as far as we can tell). This is the best I've felt in many, many years - back to normal!

But I don't know if other brands of vegan kimchi, with different recipes and ingredients and thus different microbial communities, would have worked out so well. The levels of L.sakei and other beneficial microbes in the many kimchi brands are unknown.

So now I wonder- if L. sakei is so pervasive on meat and seafood, perhaps kimchi with a seafood ingredient in it would be even better, with consistently higher amounts of L. sakei. Or maybe there is no difference between the two kinds of kimchi. Only the very expensive state-of-art genetic testing would give me the answer to that question.

Based on my successful 1 1/2 years of vegan kimchi experience, I may be willing to experiment further and try non-vegan kimchi. Or maybe not. Perhaps it is better. But I'm very cautious....

It is now over a year since I successfully started treating chronic sinusitis with kimchi, and almost a year for the other 3 family members. The kimchi treatment continues to be amazingly effective. We all continue to feel great and we have not taken any antibiotics in all this time. (See my December 6, 2013 post or the Sinusitis Treatment Summary page for details on how we do various easy Sinusitis Treatments.)

No more symptoms of acute or chronic sinusitis! We have made some recent changes though. We decided to stop doing frequent kimchi "booster" or "maintenance" treatments. Instead, we decided to only use kimchi when there is a definite need, for example after a cold or other virus when we have gone into acute sinusitis, or when our sinuses don't feel right for several days. Since adopting this policy we haven't done a kimchi treatment in over a month and continue to feel great. (Our new motto: If it ain't broke, don't fix it.)

We came to this decision because in December two of us noticed we were only getting a partial response to the brand of kimchi we had been using for almost a year, but when we switched to a new kind of kimchi (but again vegan) we once again felt fantastic. Why did this occur? I have two possible hypotheses: 1) Since kimchi contains so many types of bacteria, perhaps frequent "booster applications" also increased other bacteria in the sinuses that competed with the Lactobacillus sakei, and switching to a new kind of kimchi corrected this problem. OR 2) Perhaps the kimchi company changed their kimchi recipe or ingredients, and thus the Lactobacillus sakei numbers went way down.

We think that since we still get acute sinusitis after a cold or flu-type virus means that our sinus bacterial communities (sinus microbiome) are still not quite right, even thought they must be better than they've been in years (after all, we feel great and not ill, and have not taken antibiotics in over a year). Thus we are making every effort to eat fermented and pickled foods, fruits, vegetables, whole grains, yogurt, raw cheeses, and kefir to naturally increase our beneficial bacteria numbers. We are not taking probiotics because no brand of probiotics currently available contains Lactobacillus sakei. We are also planning to test other brands of kimchi to see what brands are effective. And, of course, I'm always looking for new sources of Lactobacillus sakei and other effective natural sinusitis treatments.
