Nosocomial spread of Enterococcus faecium resistant to vancomycin and linezolid in a tertiary care medical center

J Clin Microbiol. 2006 Sep;44(9):3368-70. doi: 10.1128/JCM.00850-06.

Abstract

In May 2004 our institution encountered its first clinical isolate of linezolid-resistant, vancomycin-resistant Enterococcus faecium (LRVRE). Between October 2004 and July 2005, 40 patients from whom LRVRE organisms were recovered in clinical specimens were characterized. Epidemiologic investigation and pulsed-field gel electrophoresis patterns indicated a clonal outbreak related to nosocomial spread.
