A total of 25 isolates of vanB-containing Enterococcus faecium were recovered from patients in a single Korean hospital over a 20-month period. There were two distinct vanB2 patterns among the 11 pulsed-field gel electrophoresis types; 17 contained the prototype vanB2 and 8 contained a novel vanB2 with a 177-bp deletion in vanY(B). Both vanB2 genes were transmissible in vitro at a mean frequenc...

aim & background : enterococci infections are public health growing concern due to the glycopeptide antibiotics resistance especially vancomycin. genes, vana, b, and h, are contributed to the influence of vancomycin-resistant enterococci (vre). this investigation aims at exploring the vre frequency and the rate of each genes in isolated enterococci from gastroenteritis patients in central regio...

Enterococci are part of the normal human flora. Enterococcus faecalis und Enterococcus faecium are the most common species isolated from human infections. Vancomycinresistant enterococci (VRE) have emerged as a major cause of nosocomial infection as early as 1986 [1]. 10 years later, >15% of nosocomial enterococcal infections in United States hospitals were due to VRE, and even higher in intens...

We examined 105 clinical isolates of glycopeptide-resistant enterococci collected from 31 U.S. hospitals in 14 states during May 1988 to July 1992. The isolates included 82 Enterococcus faecium, 8 E. faecalis, 6 Enterococcus spp., 5 E. gallinarum, 3 E. casseliflavus, and 1 E. raffinosus. The isolates were categorized into the following four phenotypes of glycopeptide resistance on the basis of ...

We evaluated the ability of the new VITEK 2 version 4.01 software to identify and detect glycopeptide-resistant enterococci compared to that of the reference broth microdilution method and to classify them into the vanA, vanB, vanC1, and vanC2 genotypes. Moreover, the accuracy of antimicrobial susceptibility testing with agents with improved potencies against glycopeptide-resistant enterococci ...
