Gene found that could make common bacteria resistant to antibiotics
Scientists think the bacteria developed resistance in pigs treated with the antibiotic colistin and it was passed to humans who ate the animals.
Pigs, like other animals raised for food, are often given antibiotics to promote growth and prevent the spread of disease among livestock. Scientists in China found a gene that makes the common bacteria Enterobacteriaceae resistant to “last-resort” antibiotics, which could pose a serious health risk if passed to other, more dangerous types of bacteria.Antibiotic resistant germs cause more than 2 million illnesses and 23,000 deaths per year, fueling searches for ways to use fewer antibiotics.
Although researchers may have found a combination of drugs could kill MRSA, researchers at South China Agricultural University said their finding points to a gene passed between more common bacteria such as E. coli, potentially a much larger problem…
