Great idea and one that this blog has been pushing for a long time - the use of beneficial bacteria to get rid of other harmful bacteria. Some researchers refer to the bacteria acting as "living antibiotics" when they overpower harmful bacteria.
Researchers such as Daniel Kadouri, a micro-biologist at Rutgers School of Dental Medicine in Newark, are studying bacteria that aggressively attack harmful bacteria, and calling them "predator bacteria". They are focusing on one specific bacteria - Bdellovibrio bacteriovorus, a gram-negative bacteria that dines on other gram-negative bacteria. They hope to eventually be able to give this bacteria as a medicine to humans , and then this predator bacteria would overpower and destroy "superbugs" (pathogenic bacteria that are resistant to many antibiotics). A great idea, but unfortunately the researchers think that it'll take about 10 more years of testing and development before it's ready for use in humans. From Science News:
The woman in her 70s was in trouble. What started as a broken leg led to an infection in her hip that hung on for two years and several hospital stays. At a Nevada hospital, doctors gave the woman seven different antibiotics, one after the other. The drugs did little to help her. Lab results showed that none of the 14 antibiotics available at the hospital could fight the infection, caused by the bacterium Klebsiella pneumoniae.... The CDC’s final report revealed startling news: The bacteria raging in the woman’s body were resistant to all 26 antibiotics available in the United States. She died from septic shock; the infection shut down her organs. ...continue reading "Will We Use Predator Bacteria To Destroy Superbugs In the Future?"
