(CNN) - As MRSA, resistant and deadly mistake to become drug-resistant bacteria, unpleasant and medical experts in health? The answer is in the genes. Researchers have pinpointed a common strain found in cattle, called Staphylococcus aureus CC398 bounced from man, when he was a treat for the animals, where it has become resistant to antibiotics. Drug-resistant staphylococcus infection was associated with over use of antibiotics in animal husbandry. This is the first study to identify genetic link between it and its implications for people. MRSA, methicillin-resistant staphylococcus gold, is a type of staphylococcus bacteria resistant to conventional antibiotics. Staph infection can be deadly especially when it occurs in people with weakened immune systems. But it usually treatable with antibiotics. The problem with MRSA, then it Superbug - can not be treated or cured conventional antibiotics. MRSA has led to 278,000 hospitalizations and more than 18000 deaths in 2005, according to one study. In a study published Tuesday in the online journal mBio, researchers in translational research in Genomics Institute at Arizona Institute in sera of Denmark and several other institutions, the sequence of genes of the bacteria. Voltage, Staphylococcus aureus CC398 early in people and more treatable with antibiotics, said Lance Price, Director of Food Microbiology and Environmental Health Translational Genomics Research Institute in Arizona. It spread to cattle, which are usually pumped with antibiotics to keep them healthy. "The line appears to have undergone a rapid radiation in combination with a jump from human to animal, which he subsequently acquired tetracycline and methicillin resistance," says the study. Metytsyllyn and tetracycline are among the most common antibiotics used to treat staph infections. The problem is the way animals are raised and pumped with antibiotics, said Price, lead author of the study. He said that farmers and herders to give millions of pounds of antibiotics farm animals to make them grow faster and prevent - not treat - diseases. This is a controversial practice that was banned in the European Union since 2006 because it promotes resistance to antibiotics. Farmers and workers are surrounded by cattle MRSA, which thrives in the cluttered, crowded and unclean food operations, said Price. They tend to be "overcrowded, there are tons of contact, the skin is compromised, and they are dirty. Now think about the introduction of antibiotics in that setting, "he said. "I can not design a better system for creating drug-resistant bacteria or Superbug, than the introduction of antibiotics in concentrated animal feeding operation cheap strattera," said Price. "It's asking for catastrophe."

Earlier this year the FDA banned a class of antibiotics in cattle, pigs, chickens and turkeys, from April 5, 2012, but some critics say it restricts only one class of drugs and that more regulation is needed to prevent more deadly strains. "It emphasizes that we use millions of antibiotics, we choice for drug-resistant bacteria to return and haunt us," said Price. .
