Overuse of antibiotics has led to bowel overgrowth of antibiotic-resistant bacteria, including
vancomycin-resistant enterococci (VRE), which are blamed for persistent and transmissible infections.
Australian researchers realized that yoghurt could be the answer for certain types of antibiotic-resistant bowel bacteria. Those yogurts that contain probiotics were found to have a beneficial effect on human gut health by helping to restore the normal gut organisms.
The researchers decided to determine if eating yogurt regularly could help clear vancomycin-resistant enterococci (VRE) from bowels.
Study results showed that 11 patients who regularly ate yoghurt containing Lactobacillus rhamnosus GG (LGG) bacteria were all free of VRE within 4 weeks while almost all the 12 patients who ate standard yoghurt without LGG remained VRE-positive after 4 weeks.
The reason behind such good probiotics effects lies in the fact that LGG can survive stomach and
bile acids to remain in sufficient numbers to reach the bowel. They are also resistant and susceptible to a range of antibiotics.
Patients had no adverse reactions from LGG in the study but the safety of probiotics in extremely unwell or immunocompromised is still uncertain and larger trials are needed to realize their effectiveness preventing primary infection.
