'Pig MRSA' came from humans, evolved via farm drugs

Geplaatste afbeelding

In the summer of 2004, a 6-month-old girl who lived in the southeastern part of the Netherlands—prime, intensive hog-farming country—went in for surgery for a birth defect of her heart. As is routine in the Netherlands, which has excellent hospital infection control, she was checked before surgery for MRSA, the drug-resistant bacterium that can live on the skin without causing infections and can be unwittingly transmitted from one patient to another. The girl was carrying MRSA, which was a surprise—but the bigger surprise was that her MRSA strain did not render any results on the standard identification test, PFGE.

Looking for a source for the mysterious strain, the hospital epidemiologists where the girl was being treated asked to check her family: father, mother, and school-age sibling. They were carrying it. They asked to check the family's social circle; some of them were carrying it too. Then, flailing about for an answer—the Netherlands has such low rates of MRSA that these persistent findings were really rather odd—the epidemiologists asked what the family and their friends all did for a living, and received the answer that they were all pig farmers. So they checked the pigs, and the pigs were carrying the MRSA strain as well. And if a new MRSA strain in humans was odd, then a MRSA strain in pigs was very odd—because swine have their own varieties of staph, and are not supposed to get S. aureus, the usually human strain that accounts for the "SA" in MRSA.
