Vancomycin resistance in gram-positive cocci.
The first vancomycin-resistant clinical isolates of Enterococcus species were reported in Europe in 1988. Similar strains were later detected in hospitals on the East Coast of the United States. Since then, vancomycin-resistant enterococci have spread with unexpected rapidity and are now encountered in hospitals in most countries. This article reviews the mode of action and the mechanism of bac...
متن کاملEnterococci and vancomycin resistance.
The frequency of infections with multiply antibiotic-resistant gram-positive bacteria is increasing, and in some cases these organisms remain susceptible only to the glycopeptides vancomycin and teicoplanin. The appearance of transferable high-level glycopeptide resistance in enterococci--producing some strains that are now resistant to all available antibiotics--is thus a cause for concern. Th...
متن کاملPerformance of the EUCAST disk diffusion method, the CLSI agar screen method, and the Vitek 2 automated antimicrobial susceptibility testing system for detection of clinical isolates of Enterococci with low- and medium-level VanB-type vancomycin resistance: a multicenter study.
Different antimicrobial susceptibility testing methods to detect low-level vancomycin resistance in enterococci were evaluated in a Scandinavian multicenter study (n=28). A phenotypically and genotypically well-characterized diverse collection of Enterococcus faecalis (n=12) and Enterococcus faecium (n=18) strains with and without nonsusceptibility to vancomycin was examined blindly in Danish (...
متن کاملSusceptibility testing and resistance phenotypes detection in bacterial pathogens using the VITEK 2 System.
A set of well characterized strains, collected in Polish hospitals, including Gram-negative (n = 93) and Gram-positive (n = 90) isolates was used in the study. The VITEK 2 AST-cards were used in the analysis according to the manufacturer's recommendations. Comparison of the susceptibility data obtained by the standard method and by VITEK 2 cards proved concordant in 99% of cases. Clinically imp...
متن کاملComparison of the Roche LightCycler vanA/vanB detection assay and culture for detection of vancomycin-resistant enterococci from perianal swabs.
We compared the performance characteristics of a real-time PCR method, the LightCycler vanA/vanB detection assay (Roche Diagnostics Corporation, Indianapolis, Ind.) to that of Enterococcosel agar (BBL, Sparks, Md.) for direct detection of vancomycin-resistant enterococci (VRE) from 894 perianal stool swabs. For 421 of 894 swabs, the result for LightCycler PCR was compared to an Enterococcosel p...
