OBJECTIVE Determine the prevalence of Vancomycin-resistant enterococci (VRE) colonizing the intestinal tract of hospitalized patients and define risk factors. MATERIAL AND METHODS A point prevalence survey of VRE fecal carriage was carried out among patients who stayed at a 600-bed teaching hospital for at least two days. Resistance to vancomycin was detected by the E-test method. Epidemiolog...

Vancomycin-resistant enterococci (VRE) are common hospital pathogens that are resistant to most major classes of antibiotics. The incidence of VRE is increasing rapidly, to the point where over one-quarter of enterococcal infections in intensive care units are now resistant to vancomycin. The exact mechanism by which VRE maintains its plasmid-encoded resistance genes is ill-defined, and novel t...

UNLABELLED Sewage spills can release antibiotic-resistant bacteria into surface waters, contributing to environmental reservoirs and potentially impacting human health. Vancomycin-resistant enterococci (VRE) are nosocomial pathogens that have been detected in environmental habitats, including soil, water, and beach sands, as well as wildlife feces. However, VRE harboring vanA genes that confer ...

OBJECTIVE To document the risk of the development of vancomycin-resistant bacteria in a population of seriously burned patients during a 10-year period of common vancomycin hydrochloride use. DESIGN Retrospective study. SETTING The US Army Institute of Surgical Research, Burn Center, Fort Sam Houston, Tex. POPULATION AND METHODS Microbiology, infection, and antibiotic use records collecte...

After they were first identified in the mid-1980s, vancomycin-resistant enterococci (VRE) spread rapidly and became a major problem in many institutions both in Europe and the United States. Since VRE have intrinsic resistance to most of the commonly used antibiotics and the ability to acquire resistance to most of the current available antibiotics, either by mutation or by receipt of foreign g...

Vancomycin and ampicillin resistance in clinical Enterococcus faecium strains has developed in the past decade. Failure to adhere to strict infection control to prevent the spread of these pathogens has been well established. New data implicate the use of specific classes of antimicrobial agents in the spread of vancomycin-resistant enterococci (VRE). Extended-spectrum cephalosporins and drugs ...

Acquired vancomycin resistance in Gram-positive anaerobes has been reported only in Australia and Canada from rare vanB-positive stool samples in the absence of vancomycin-resistant enterococci (VRE). We report the emergence of VanB-type resistance in Clostridium clostridioforme and Atopobium minutum involved in human infections in France.

background: to determine the species distribution, updated drug susceptibility patterns and genes conferring resistance in clini­cal vancomycin resistant enterococcal (vre) isolates. methods: clinical enterococcal isolates collected during 7 months, from september 2005 to april 2006 from hos­pitalized pa­tients and outpatients were studied. twenty five vre were isolated from 450 enterococci sam...

BACKGROUND Antimicrobial resistance is a serious threat in veterinary medicine and human healthcare. Resistance genes can spread from animals, through the food-chain, and back to humans. Sewage sludge may act as the link back from humans to animals. The main aims of this study were to investigate the occurrence of vancomycin resistant enterococci (VRE) in treated sewage sludge, in a Swedish was...

In a recently published article, Peltroche-Llacsahuanga and colleagues (2) compared the performance of two chromogenic media, i.e., chromID VRE (bioMérieux, Marcy l’Etoile, France) and CHROMagar VRE (Chromagar, Paris, France). Screening 259 stool samples for vancomycin-resistant enterococci (VRE), they detected a total of 55 vancomycinresistant Enterococcus faecium isolates, 54 of them harborin...
