Discovery will help to fight with hospital inflections

Researchers from several Russian universities described two new viruses capable of destroying bacteria that cause infectious outbreaks in medical institutions.

As scientists have found, viruses AS11 and AS12 successfully destroy the Acinetobacter baumannii bacteria found in hospitals. Bacteria are resistant to antibiotics, disinfectants and ultraviolet radiation.This is due to the presence of a thick protective layer that bacteria may have. «This microorganism can cause a variety of infectious complications in intensive care and burns units», — the press service of the Moscow Institute of Physics and Technology (MIPT), whose scientists took part in the study told.

Researchers have investigated the viruses` behavior on bacterial samples from 53 medical institutions. It turned out that new viruses quickly penetrate into the bacterial cell, destroying it and leave a lot of offspring, which destroys the remaining cells of bacteria. «Bacteriophages are able to increase their population until all bacterial cells sensitive to them are destroyed», — the MIPT explained.

The results of the study are published in Viruses. The study involved scientists from the Smolensk Medical University, State Scientific Center for Applied Microbiology and Biotechnology, Russian Academy of Sciences, Skolkovo Institute of Science and Technology, St. Petersburg Medical University, and Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry, RAS.

Later, new viruses may be used for the treatment and prevention of complications caused by bacteria Acinetobacter baumannii.

It should be noted, that in the Russian Federation the research direction of creating drugs with bacteriophage viruses has traditionally been highly developed. In the USSR, research began in the 30s of the last century. The direction became again promising with the growing number of bacteria resistant to antibiotics.
