Antibiotic-Resistant Bacteria Spreading

From Future Pundit:

erome Groopman has a good article in The New Yorker surveying the growing threat of antibiotic-resistant bacteria.

Of the so-called superbugs—those bacteria that have developed immunity to a wide number of antibiotics—the methicillin-resistant Staphylococcus aureus, or MRSA, is the most well known. Dr. Robert Moellering, a professor at Harvard Medical School, a past president of the Infectious Diseases Society of America, and a leading expert on antibiotic resistance, pointed out that MRSA, like Klebsiella, originally occurred in I.C.U.s, especially among patients who had undergone major surgery. “Until about ten years ago,” Moellering told me, “virtually all cases of MRSA were either in hospitals or nursing homes. In the hospital setting, they cause wound infections after surgery, pneumonias, and bloodstream infections from indwelling catheters. But they can cause a variety of other infections, all the way to bacterial meningitis.” The first deaths from MRSA in community settings, reported at the end of the nineteen-nineties, were among children in North Dakota and Minnesota. “And then it started showing up in men who have sex with men,” Moellering said. “Soon, it began to be spread in prisons among the prisoners. Now we see it in a whole bunch of other populations.” An outbreak among the St. Louis Rams football team, passed on through shared equipment, particularly affected the team’s linemen; artificial turf, which causes skin abrasions that are prone to infection, exacerbated the problem. Other outbreaks were reported among insular religious groups in rural New York; Hurricane Katrina evacuees; and illegal tattoo recipients. “And now it’s basically everybody,” Moellering said. The deadly toxin produced by the strain of MRSA found in U.S. communities, Panton-Valentine leukocidin, is thought to destroy the membranes of white blood cells, damaging the body’s primary defense against the microbe. In 2006, the Centers for Disease Control and Prevention recorded some nineteen thousand deaths and a hundred and five thousand infections from MRSA.
