Comparison of eight methods to detect vancomycin resistance in enterococci.
A collection of genetically unrelated vancomycin-resistant enterococci (VRE) including 50 vanA, 15 vanB, 50 vanC1, and 30 vanC2 VRE were used to evaluate the accuracy of eight currently available susceptibility test methods (agar dilution, disk diffusion, E-test, agar screen plate, Vitek GPS-TA and GPS-101, and MicroScan overnight and rapid panels). vanA VRE were detected by all methods. vanB V...
متن کاملImproving the assessment of vancomycin-resistant enterococci by routine screening.
BACKGROUND As infection with vancomycin-resistant enterococci (VRE) increases in hospitals, knowledge about VRE reservoirs and improved accuracy of epidemiologic measures are needed. Many assessments underestimate incidence by including prevalent carriers in at-risk populations. Routine surveillance cultures can substantially improve prevalence and incidence estimates, and assessing the range o...
متن کاملNovel screening agar for detection of vancomycin-nonsusceptible Staphylococcus aureus.
In January 2006, the Clinical and Laboratory Standards Institute (CLSI) updated breakpoints for vancomycin susceptibility testing for Staphylococcus aureus such that an MIC greater than 2 mg/liter was considered to represent nonsusceptibility to vancomycin. Previously, an MIC of 4 mg/liter had been considered to represent susceptibility. Additionally, in 2009, the CLSI altered the guidelines fo...
متن کاملEvaluation of PCR-based screening for vancomycin-resistant enterococci compared with a chromogenic agar-based culture method.
Rapid detection of vancomycin-resistant enterococci (VRE) infection is very important for control and prevention of nosocomial spread of these bacteria. A multiplex PCR method for rapid screening of VRE has recently been developed. We performed a prospective study of VRE screening tests to compare the performance of PCR to that of a chromogenic agar-based culture method. From January to Decembe...
متن کاملComparison of simple and rapid methods for identifying enterococci intrinsically resistant to vancomycin.
Three different methodologies, reduction of litmus milk (LM) and acidification of arabinose (ARA), acidification of methyl-alpha-D-glucopyranoside (MGP), and rapid motility (RM), for differentiating isolates of Enterococcus casseliflavus and Enterococcus gallinarum (intrinsically vancomycin-resistant enterococci [IVRE]) from Enterococcus faecalis and Enterococcus faecium were evaluated. All 33 ...
