BACKGROUND The use of vancomycin has continued to expand because of the increasing number of patients infected or colonized with methicillin-resistant Staphylococcus aureus, causing an increase in the prevalence of vancomycin-resistant Enterococcus (VRE). METHODS Review of the pertinent English language literature. RESULTS Vancomycin-resistant Enterococcus spp. are being identified more oft...

The presence of Enterococcus-associated vancomycin resistance genes vanA, vanB, vanD, vanE, and vanG in rectal swabs was investigated in two hospitals using PCR. All vanA genes detected were associated with vancomycin-resistant enterococci (VRE), whereas VRE-associated vanB genes were detected in only one hospital (4.7%). However, in both hospitals, high prevalences of vanB (6.2 and 2.3%), vanD...

Vancomycin-resistant enterococci (VRE) were detected in two faecal samples (1.3%) of song thrush in Portugal. vanA isolates showed high level vancomycin/teicoplanin resistance, as well as resistance to ciprofloxacin, quinupristin-dalfopristin and cloranfenicol. Thrush can be a reservoir of VRE and transmit these resistant bacteria to other animals including humans.

The incidence of nosocomial infections caused by vancomycin-resistant enterococci has risen substantially during the past 15 years. We report the use of linezolid for the successful treatment of hip prosthesis infection associated with osteomyelitis due to vancomycin-resistant Enterococcus faecium.

To determine patterns of antimicrobial susceptibility among enterococci and to assess molecular characteristics of vancomycin-resistant enterococci, 157 clinical blood isolates of enterococci from 10 hospitals in Cincinnati, Ohio, were prospectively collected during a 6-month period from February to July 1995. The isolates included 108 (69%) E. faecalis isolates, 46 (29%) E. faecium isolates, a...

Vancomycin resistant enterococci are increasingly being isolated from inpatients. This report describes the colonial variation present in most isolates of vancomycin resistant Enterococcus faecium obtained at this hospital. Colonial variants within the same culture were indistinguishable by antimicrobial susceptibility, biochemical reactions, and ribotyping. Failure to appreciate this colonial ...

To understand quinupristin-dalfopristin resistance among clinical isolates of gram-positive bacteria in Taiwan, where this agent is not yet available for clinical use, we evaluated 1,287 nonduplicate isolates recovered from January 1996 to December 1999 for in vitro susceptibility to quinupristin-dalfopristin and other newer antimicrobial agents. All methicillin-susceptible Staphylococcus aureu...
