UNLABELLED Nosocomial outbreaks of vancomycin-resistant Enterococcus faecium (VREfm) are thought to occur by transmission of VREfm between patients, predicting that infection control interventions will limit cross-transmission. Despite implementation of such strategies, the incidence of VREfm infections continues to rise. We aimed to use genomics to better understand the epidemiology of E. faec...

A multiplex PCR assay was developed for detection of the six types of glycopeptide resistance characterized in enterococci and for identification of Enterococcus faecium, Enterococcus faecalis, Staphylococcus aureus, and Staphylococcus epidermidis at the species level. Primers targeting the genes vanA, vanB, vanC, vanD, vanE, vanG, and ddl of E. faecium and E. faecalis and nuc of S. aureus and ...

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...
