The bacteria Fusobacterium nucleatum is prevalent in periodontal disease (gum disease), but also in some chronic diseases and cancers, such as colorectal cancer. The bacteria F. nucleatum is normally found in the mouth (oral) microbiome, and its numbers increase as periodontal disease inflammation increases.

It is thought that sometimes the bacteria leaves the mouth and travels to other parts of the body, where it can promote cancer and other diseases.

A recent study found that the antibiotic FP 100 (Hygromycin A) totally eliminates the F. nucleatum bacteria in the mouth, and without causing harm to the mouth microbiome or gut microbiome. This is because it is a narrow spectrum antibiotic - only targets the harmful bacteria, and not all (both good and harmful) bacteria. While the study was only done in mice, this is promising and welcome news.

Eliminating the harmful bacteria in the mouth would potentially prevent some chronic diseases and cancers. Now we need further studies to see if this finding holds up in humans.

From Medical Xpress: First narrow-spectrum antibiotic successfully eliminates  Fusobacterium nucleatum, a gum disease pathogen

In a study published in the Journal of Oral Microbiology, ADA Forsyth scientists found that FP 100 (Hygromycin A), a first-in-class, small molecule, narrow-spectrum antibiotic, successfully eradicates Fusobacterium nucleatum without harming the oral or gut microbiomes. ...continue reading "A Promising Antibiotic For Gum Disease"

Could this be true for humans - that antibiotics can treat endometriosis? A nicely done series of studies found that treatment with the antibiotic metronidazole reduced both early growth and progression of endometrial lesions. Also, the researchers found microbiome (community of microbes) differences in endometriosis vs healthy  subjects. The researchers felt that the research results suggest that gut bacteria promote endometriosis progression, and that the antibiotics worked to stop the progression of endometriosis because it reduced specific gut bacteria.

Endometriosis is a chronic condition causing abdominal pain and infertility and afflicts up to 10% of women between the ages of 25 and 40. Unfortunately, current treatments , including hormone therapy and surgery, have serious side effects and do not prevent recurrences. So a study finding another treatment approach is exciting. But...before everyone gets too excited, keep in mind that the series of studies were done in mice, but... the researchers of the study are optimistic that this could be true for women also. And yes, the Washington University School of Medicine (in St. Louis, Missouri) researchers are going to  conduct a large clinical trial to test the antibiotic metronidazole in women with endometriosis.

From Medical Xpress: Antibiotics may treat endometriosis

Researchers at Washington University School of Medicine in St. Louis have found, in mice, that treatment with an antibiotic reduces the size of lesions caused by endometriosis. The researchers are planning a large, multicenter clinical trial to test the drug metronidazole in women who have the painful condition.  ...continue reading "Could Antibiotics treat Endometriosis??"
