VU scientists found a cold virus that would protect us from bacteria



Research has shown that on the surface of fruits and berries, and plant useful and potentially pathogenic bacteria, for example, Enterobacteriaceae family salmonella. Escherichia. Pantoea genital enterobacteriaceae. They are also called intestinal bacteria and are associated with various dietary infections. Research has identified more than 50 bacterial infectious viruses – VU GMC researchers have found that most of these viruses develop at lower intestinal temperatures.

"Since we have distinguished a large number of different viruses, we could more accurately estimate their ability to multiply at different temperatures. Most enterobacteria are accustomed to our body temperature, which means that the optimal conditions for their reproducibility are 37 degrees, so their viruses need to be adapted We did not see that the viruses in the Czech Republic or Lithuania like heat – we have found more adapted to develop at a much lower body temperature than the temperature, which is called cold-labeled or psychophilic, so we do not see the effect of the warming climate on the level of microorganisms , but it can be assumed to be felt after five or even ten years. So far, microorganisms have not yet responded to climate warming, "says Dr. L. Kalinienė. It predicts that if the climate continues, the number of enterobacteria will increase, as it will help them survive and develop more favorably.

Department of Molecular Microbiology and Biotechnology at VU GMC Institute for Biochemistry is the only in the world E. coli directed cold bloodstream viruses. "The first is the discovery of such viruses, the first to announce this phenomenon and the only one in the world we have E. coli collection of infectious viruses cold blood. So far, we have described seven such viruses in the scientific press, but we have more, "says VU GMC virologist.

Cold-blooded viruses can only be used to kill pathogenic bacteria in the clinic, but also to preserve foodstuffs to prevent their colonization of bacteria because these very numerous viruses can develop not only at extremely low temperatures (4 ° C) but also in non-shared bacterial cells. "We do not know why cold-blooded viruses are such, but they may be so comfortable, because everyone else develops in heat. Cold bloodstreams are adapted to unpleasant conditions, so they can replace household chemicals or agrochemicals," says Dr. L. Kalinienė.

According to the scientist, global strains of antibiotic resistant bacteria used in medicine are increasing worldwide. According to the World Health Organization, every year more than 50,000 people in the European Union and the United States. people die of infections caused by such bacteria. It is believed that by 2050 this number will exceed 10 million worldwide. To solve this problem, bacterial viruses, as well as a cold meal, may be useful, but it is necessary to understand the molecular developmental features of such viruses, which is the goal of further research on VU GMC researchers.
