Surveillance of Vancomycin-resistant Enterococci colonization with GeneXpert vanA/vanB test and culture method
Objectives: Early detection of vancomycin resistant enterococci (VRE) colonization in hospitalized patients plays an important role in controlling enterococcal infections. For this purpose, the detection of VRE from rectal swab specimens can be performed with various methods. Methods: In this study, VRE colonization in the rectal swab samples of patients from intensive care units, burn unit, an...
متن کاملEvaluation of the EVIGENE VRE detection kit for detection of vanA and vanB genes in vancomycin-resistant enterococci.
The aim of this study was to evaluate the performance of the EVIGENE VRE Detection kit and compare it with PCR, considered the gold standard for detection of vancomycin-resistant enterococci (VRE). The correlation between the MIC values of vancomycin and teicoplanin using the epsilon test was also determined. In the EVIGENE VRE Detection kit, DNA probes specific for bacterial target DNA sequenc...
متن کاملFrequency of VanA, VanB and VanH variants amongst vancomycin-resistant enterococci isolated from patients in central region of Iran
AIM The aim of this study was to investigate the VRE frequency and the rate of each gene in isolated enterococci from patients with intestinal infection in the central region of Iran. BACKGROUND Enterococci infections are a public health growing concern due to the glycopeptide antibiotics resistance especially vancomycin. Genes, vanA, B, and H contribute to the influence of vancomycin-resista...
متن کاملComparison of PCR and culture for screening of vancomycin-resistant Enterococci: highly disparate results for vanA and vanB.
We compared PCR to conventional culture for the detection of vancomycin-resistant enterococci (VRE) in 30,835 rectal samples over a 3-year period. The positive and negative predictive values of vanB PCR were 1.42% and 99.9%, respectively. A positive vanB result by PCR is poorly predictive and necessitates culture for differentiation of VRE-positive and -negative individuals.
متن کاملEvaluation of the iNtRON VRE vanA/vanB Real-Time PCR Assay for Detection of Vancomycin-Resistant Enterococci
BACKGROUND Recently, the iNtRON VRE vanA/vanB real-time PCR (iNtRON; iNtRON Biotechnology, Korea) assay, a multiplex real-time PCR method, was introduced. In this prospective study, we compared the iNtRON assay with the Seeplex VRE ACE detection kit (Seeplex; Seegene, Korea), a conventional multiplex PCR assay. METHODS A chromogenic agar-based culture, in which pre-selected vancomycin-resista...
