MRSA Notes

Scary stuff here, again reported at the IDSA annual meeting:

“SAN FRANCISCO, Oct. 10 - In the first reported hospital outbreak of Zyvox (linezolid)-resistant enterococcus, only half the infected patients had a history of Zyvox exposure, suggesting that some cases were nosocomial infections, researchers reported.

Clinicians have seen Zyvox- and vancomycin-resistant enterococcus sporadically since the new antibiotic was developed. "Most of the cases of linezolid-resistant enterococcus described in the literature involve patients who had prior exposure to linezolid [Zyvox]," said Rose Devasia, M.D., an infectious disease fellow at Vanderbilt University.

However, in the current study, only eight of 15 patients had previous exposure to Zyvox, Dr. Devasia reported at a meeting of the Infectious Disease Society of America here.”
