Antibiotic-resistant bacteria are becoming an increasingly large problem, and according to Professor Dame Sally Davies (the government’s chief medical officer in England), this danger should be added to the list of potential threats to the UK which also includes terrorism.

Antibiotic-resistant pathogenic bacteria are a pretty serious global issue, especially in hospitals, and Dame Sally believes that within 20 years, routine operations such as hip replacements and organ transplants may become riskier and more deadly. She also mentioned that although new pathogens are emerging and mutating each year to become resistant to current antibiotics, no new classes of antibiotics have been developed since the 1980’s! This is likely due to factors including extremely high costs and volumes of research necessary in developing new medicines such as antibiotics.

Antibiotic-resistance is due to a range of factors including the overuse of antibiotics in food production (animal farming, fishing and agriculture), as well as poor education for medical students and doctors about appropriate use of antibiotics. This includes making sure that antibiotics are not used for viral coughs and colds which, by nature, do not even respond to antibiotics (antibiotics will only target bacteria)!

Hospitals are a breeding ground for antibiotic-resistant bacteria. Read more about the over-prescription of antibiotics here.

So what can we do about this very serious threat to our health? Some recent research suggests there may be new possibilities for good bacteria, or probiotics to combat antibiotic resistant pathogens.

In the study, the Spanish and American researchers explained that one of the side effects of taking antibiotics is a decrease in the microbial diversity in the gut. This reduced diversity allows antibiotic- resistant pathogens including vancomycin-resistant-enterococci (VRE), to make the most of this opportunity by invading the gut and multiplying.

The researchers found that if they improved the microbial diversity in the intestines of the subjects with the bacterial species Barnesiella (which were measured in the faecal samples of the subjects), that there was a billion-fold reduction in VRE. Now that is pretty impressive! Introducing Barnesiella was shown to therefore improve the clearance of antibiotic resistant pathogens such as VRE, whilst restoring healthy microbial balance.

These results may now pave the way for the development of new probiotic products which are specifically designed to combat antibiotic resistant pathogens. Watch this space!

Now I like to think of probiotics as the peace keepers of the digestive system, and if antibiotic resistant bacteria have been likened to being a similar threat to us as terrorism is, than I am glad we have friendly bacteria on our side!

While we are on the subject of antibiotics, if you do need to take them, we have a special little product designed specifically For those on antibiotics.

  • Hello Optibac Probiotics

    I have antibiotic resistant enterrococcus. I discovered this page after trawling through some research papers that also mentioned Barnesiella's potential for VRE. Please could you tell me how or where this bacteria could be available?

  • .Hello Sandy,

    Thank you for your question, and sorry that you're struggling with a resistant bug.

    I'm afraid that, as far as we are aware, Barnesiella is not yet available commercially as a probiotic as research into its potential benefits is still ongoing.
    Until such time as VRE-specific probiotics are available, the best that we can do is to ensure that our resident flora is working for us and not against us. It can therefore be a good plan to try taking a well-researched combination probiotic to ensure that a significant influx of beneficial bacteria or yeasts are being consumed to help keep our gut flora in good shape.
    Don't forget that our gut flora can be positively or negatively affected by our diet and lifestyle too, so if we want to feed our good bacteria and not the bad, we need to keep sugary foods to a minimum and instead consume plenty of fresh fruits, vegetables as part of a healthy balanced diet.

    I'll email you directly with some individual recommendations.

    With best wishes,

    Kerry
