Hospital bacteria from cows


Researchers from University of Edinburgh think that the hospital bacteria MRSA was found on cattles and was resistant only after the transition to humans. It should be apparent after genome analysis of bacteria.  
MRSA stands for Methicillin-resistant Staphylococcus aureus , a bacterium that is resistant to methicillin, a widely used antibiotic. It is also known as the hospital bacterium, because they have common. The bacterium causes painful infections of the skin and soft tissue, and affects more people. Scientists studied the CC97 variant. They took samples from 43 different sources, both humans and animals. To be able to set up a “family tree” she unraveled the genome of the bacteria 43. “Bacteria that bovine derived, are quite deep into the schedule,” says researcher Ross Fitzgerald. “So we came to the conclusion that the bacteria evolved from cattle to human variation.” After the jump from cow to human would have its bacteria developed resistance to methicillin. Only the human variant is resistant against it. The exact origin of the human bacteria is not known. Previous research suggested that the bacteria of pigs come, and all were resistant to they took the plunge. Therefore, according to Fitzgerald more research is needed to the origin of MRSA to definitively determine. Then there is a drug to be developed to avoid.
