A team of doctors at Peter Doherty Institute for Infection and Immunity based in Melbourne studied about a common hospital nuisance called Vancomycin-resistant enterococci (VRE) or Enterococcus faecium.

The study carried out gives a bizarre result that bacteria may have learned the art to evade alcohol. The recent evolution on the part of Bacteria can increase the problems for hospitals which already suffer from drug-resistant superbugs.

It is important to note that, alcohol is used in many anti-bacterial products like hand sanitizers and disinfectants used by hospitals to control infection.

Bacteria evolving to evade alcohol comes as surprise for many microbiologists having a notion that it could never be possible.

According to the World Health Organisation, antibiotic-resistant bacteria are a fundamental threat and it important to ensure a counter to them.

A doctor from Doherty Institute says that they started to notice an increase in the VRE infections. They conducted a chain of experiments and in one of the experiments they too the samples of VRE dating back to 1997 and 2015 respectively. They were grown in dishes with diluted alcohol with the newer samples growing better.

The team identified and documented changes which have occurred over the years which helped to give explanations about increased tolerance of bacteria.
