A New Superbug?
Scientists have discovered a new, highly-transmissible gene that could, quite easily in fact, open a frightening new front in the ongoing global war against superbugs.
The antibiotic-resistant gene, NDM-1, was first identified in 2008 a Swedish patient that had received hospital care in New Delhi. NDM-1 produces an enzyme that allows bacteria to destroy most antibiotics. It exists on plasmids, which are pieces of genetic material that are easily shared between bacteria including E coli and other species that can cause pneumonia, urinary tract infections, and blood stream infections.
NDM-1 probably evolved in parts of India where poor sanitation and overutilization of antibiotics provide a perfect environment for the creation of antibiotic-resistant bacteria.
The gene has been identified in three U.S. patients. All had received medical treatment in India, and all recovered from their infections. It has been found sporadically in Britain, Australia and nearly a dozen other countries as well. Most affected patients were “medical tourists” — that is, people seeking less expensive medical care in India.
“We need to be vigilant about this,” said Arjun Srinivasan, an epidemiologist at the CDC told the Washington Post. “This should not be a call to panic, but it should be a call to action. There are effective strategies we can take that will prevent the spread of these organisms.” Read more »
