Bacteria resistant to antibiotics is detected in humans and cows
June 2, 2011 ? 21h47
A group of scientists found in humans and cows a new strain of Staphylococcus aureus resistant to antibiotics of the penicillin group, published the journal Lancet Infectious Diseases.
The veterinary epidemiologist Spanish Laura Garcia-Alvarez, associate researcher at Imperial College London, identified several bacteria that showed signs of resistance to antibiotics and that the tests did not detect normal. The researcher made the discovery while preparing his doctoral thesis at Cambridge University.
The new strain of methicillin-resistant Staphylococcus aureus (MRSA, the acronym in English), contains a gene called mecA, responsible for antibiotic resistance, which only has a 60% level of similarity of those who share 99% of MRSA known. Why the new strain go unnoticed in clinical trials, said Laura to Agencia EFE.
After identifying 13 samples of the bacterium, known as LGA251, in cow's milk, the researchers detected 50 human cases in the UK and Denmark in 2010 and are currently developing the first tests in other European countries like Portugal, Germany and Holland.
"The first bacterium of this type comes from a 1975 show, so it takes at least 36 years in circulation, but not detected until now because we did not have the necessary tools," he said.
Professor of Preventive Veterinary Medicine, University of Cambridge Mark Holmes, who led the research, said that the bacterium has a wide geographical distribution, but its incidence in absolute numbers is very low, but has not ruled out an increase in cases in coming years when we extend the new clinical tests to detect it.
Scientists have not determined whether bacteria were extracted from cattle to humans now, or otherwise, but in any case, claimed that the consumption of cow's milk does not pose any risk of contagion, since the process of pasteurization eliminates completely Staphylococcus aureus.
It is estimated that one third of people have in your body are resistant to antibiotics, especially in skin and nasal passages, although the medical complications associated with MRSA usually occurs in patients undergoing any hospitality operation.
In patients with a weakened immune system, these bacteria can cause anything from skin problems to blood infections.
The Staphylococcus aureus are largely responsible for hospital infections, and cause medical problems to 2% of patients admitted to a clinic in the UK, according to data from the Wellcome Trust Sanger Institute, who participated in the genetic analysis of microorganisms.
In industrialized countries, the bacteria are increasing their resistance to antibiotics in recent years, and it is estimated that between 40% and 60% did not respond to treatment with common antibiotics
