Scientists: bacteria become resistant to alcoholic disinfectants

Medical facilities may soon require new methods to combat hospital-acquired infections, because some bacteria acquire resistance to alcohol disinfectants, according to scientists.

As you know, disinfectants alcohol-based, in particular based on isopropanol, remain common methods of nosocomial infections. With their help, managed to prevent thousands of deaths from methicillin-resistant Staphylococcus aureus (MRSA). However, scientists have discovered that superbugs – vancomycin-resistant enterococci (VRE) are more resistant to alcohol.

In the study, the bacteria Enterococcus faecium were treated with a solution based on isopropanol for five minutes. Just used 139 samples obtained in the hospitals of Melbourne from 1997 to 2015.

“We found that samples taken after 2010, was 10 times more resistant to alcohol than the earlier samples,” write the researchers in an article published in Science Translational Medicine.

In their opinion, it is an alarming sign for medical institutions worldwide, and to control the spread of VRE need to take additional measures, and “not just relying on sanitizers alcohol-based”. Scientists recommend the use of chlorine-based products and efforts for a more active detection of infected patients.

Scientists reminded that one of the most common types of VRE is Enterococcus faecium, most of the infections which are registered in England and Australia.
