Many of the relevant genes are the same ...

The researchers found the same for in and out of clinics around the world. Matches to prove that two groups of bacteria recently shared these genes, but not to set the direction of exchange. Results will be presented Feb. 20 at the annual meeting of the American Association for the Advancement of Science in Vancouver, British Columbia. The presentation is part of a discussion titled Winning: superbakteriy or observation and science? Most antibiotics used today are made of soil bacteria, so it is not surprising that the same bacteria genes to resist antibiotics, says a leading Gautam Dantas, PhD, assistant professor of pathology and immunology. Antibiotic resistance genes probably already over billions of years in the soil, but we wanted to take the first glance, really any of them is an exchange of bacteria that cause human disease. Using samples of soil from sites in the United States, Dantas and his colleagues have identified several genes of resistance to antibiotics in soil bacteria that can withstand five classes of antibiotics, including forms of penicillin, tetracycline and sulfonamide. They found seven genes, some of which seem to come together to collectively use all known antibiotic resistance strategy: block or remove antibiotics from infected cells the host, directly attacking buy strattera or changing antibiotic bacterial protein target of the antibiotic. Those genes of resistance to antibiotics are present, often well cluster arrangements in samples of bacteria from medical clinics around the world. Many of the relevant genes were identical not only in parts of genes that encode proteins, but also in adjacent sections nekoduyuchyh. Bacterial DNA accumulates mutations and other changes are usually much faster than human DNA. Lack of changes in antibiotic resistance genes found in the study shows that gene transfer should take place relatively recently during evolution. We do not know yet how difficult translation of these genes for our efforts to combat infectious diseases, said Kevin Forsberg, PhD Laboratory Dantas who led the research. There are many such clusters antibiotic resistance on the hands, or we simply povezty the opening of this powerful group in our first assessment? I suspect that the soil is full of tank resistance genes to antibiotics, Dantas said. But when we dump antibiotics into the environment, because our society does in different contexts, we can enrich that reservoir, and that can make the antibiotic resistance genes more accessible to infectious bacteria. Dantas presentation will also be presented early research he conducted in the presence of antibiotic resistance genes in the human gut microbes.
