Multiplex PCR detection of vanA, vanB, vanC-1, and vanC-2/3 genes in enterococci.
Vancomycin-resistant enterococci (VRE) are increasingly isolated from clinical specimens. One hundred clinical isolates of enterococci (E. casseliflavus/E. flavescens [n = 10], E. faecalis [n = 34], E. faecium [n = 43], E. avium [n = 1], E. gallinarum [n = 11], and E. raffinosus [n = 1]) were examined for the presence of vanA, vanB, vanC-1, and vanC-2/3 genes by a single multiplex PCR performed...
متن کاملDetection and differentiation of vanC-1, vanC-2, and vanC-3 glycopeptide resistance genes in enterococci.
The VanC phenotype, as found in Enterococcus gallinarum, E. casseliflavus, and E. flavescens, is characterized by intrinsic low-level resistance to vancomycin. The nucleotide sequences of the vanC-1 gene in E. gallinarum, the vanC-2 gene in E. casseliflavus, and the vanC-3 gene in E. flavescens have been reported, although there is some disagreement as to whether E. flavescens is a legitimate e...
متن کاملDetection of both vanA & vanB genes in vanA phenotypes of Enterococci by Taq Man RT-PCR
Twenty seven isolates of vancomycin resistant Enterococci based on the disk diffusion and E- test have been screened; being found eight (0.3%) clinical isolates of vanA & vanB through Taq Man Real Time PCR assay. This study shows the presence of both vanA & vanB genotypes in vanA phenotypes clinical isolates in the three hospitals in Iran.
متن کاملتشخیص ژن‌های vanA, vanB, vanC با روش Multiplex-PCR در ایزوله‌های انتروکوکوس فکالیس و انتروکوکوس فسیوم در بیماران بستری
Background & Aims : After Vancomycin resistant Enterococci (VRE) was first detected in the mid 1980s, VRE spread rapidly worldwide and became one of the most serious problems in many hospitals specially in hospitalized patients. Among different enterococcal species Enterococcus feacalis and Enterococus faecium are the leading causes of life threatening infections. VanA/B/C genes are respons...
متن کاملMultiplex PCR for simultaneous detection of enterococcal genes vanA and vanB and staphylococcal genes mecA, ileS-2 and femB.
The experimental transfer of the vanA gene cluster from Enterococcus faecalis to Staphylococcus aureus has raised fears about the occurrence of such genetic transfer in clinical isolates of methicillin-resistant staphylococci. Recently, infections by a S. aureus strain carrying the enterococcal vancomycin resistance vanA gene cluster were reported. The possible emergence and dissemination of th...
