Bacteria strain that causes hard to treat staph infection probably developed its resistance to antibiotics in food animals, a group of scientists announced Tuesday. Strain of Staphylococcus aureus, known as methicillin-resistant staphylococcus gold or MRSA CC398, most commonly affects agricultural workers who come into contact with infected pigs, turkeys, or cows. The bacterium was found in about half of the samples of meat throughout the country. Researchers say that excessive use of antibiotics in livestock eat guilty in drug-resistant infection. [We can not blame nature or microbes. It is our misuse of antibiotics, which are now coming back to haunt us, Paul Keim, one of the authors of the study, said in a statement. Researchers believe that bacteria first human strain, which was easily treated with tetracycline and methicillin, antibiotics that are regularly supplied to the farm animals. Once the animals, he developed a resistance and was accepted back into a man. CDC has long said the use of antibiotics in livestock may be problematic, stating that food can be a source of antibiotic-resistant genes, but recognizes that quantify the extent to which this contributes to the problem of food security difficult. Now, scientists seem to have confirmed that without a doubt. We have seen this occur in real time, and it very rapidly, says Lance Price, lead author of the report to be published in

mBio. Strain also demonstrates the potential for transmission from person to person, which increases the likelihood of an outbreak. Price says that this is hardly the only strain that developed resistance to antibiotics in animals. I think this has happened several times in the past, and it will occur several times purchase strattera in the future, he says. [Physicians are beginning to prescribe antibiotics less fear of a superbakteriy, but their use in food animals, not less important for drug resistance development, says the price. We have tons of message out there to tell doctors to stop the appointment, tell parents not to ask for antibiotics every time their child has nasal congestion, said price. Meanwhile, we use 29000000 pounds of antibiotics for food. These examples can not be more polar opposites. In 2006, the European Union banned the use of antibiotics in animal husbandry for non-medicinal purposes. In the United States, antibiotics are commonly used on livestock to promote their growth and potential preventive treat diseases, acquired from the cramped conditions of life. Scientists estimate that about 80 percent of all antibiotics used on livestock. In Congress, a member of the House of Representatives Louise Slaughter is pushing legislation that regulates the use of antibiotics in animals to be used in food. I can not emphasize enough the urgency of the problem, she said in a statement last year. When we go to the store to pick up dinner, we should be able to buy food without worrying that food would be subjected to our family of potentially deadly bacteria that no longer respond to our treatment. Last week, it confirmed the importance of restraint in requesting more than 60 fast-food companies to voluntarily disclose whether they raise their animals antibiotics or not. Very simply, consumers are entitled to know that their food, she writes. It's like that old commercial where the flesh? "We just want to know" that the beef? "
