Isolation of glycopeptide resistant Streptococcus gallolyticus strains with vanA, vanB, and both vanA and vanB genotypes from faecal samples of veal calves in The Netherlands

Detection 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.

VanB phenotype-vanA genotype Enterococcus faecium with heterogeneous expression

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...

VanA and VanB Positive Vancomycin-resistant Staphylococcus aureus Among Clinical Isolates in Shiraz, South of Iran.

OBJECTIVE The purpose of this study was to determine the prevalence of vancomycin-resistant Staphylococcus aureus isolated from clinical samples in Shiraz hospitals. METHODS From March to December 2012, 100 S. aureus isolates (mainly from wound and blood) were collected from three hospitals in Shiraz, south of Iran. After identification of Staphylococcus aureus by biochemical, microbiological...

Moderate-level resistance to glycopeptide LY333328 mediated by genes of the vanA and vanB clusters in enterococci.

Three of five natural plasmids carrying a wild-type vanA gene cluster did not confer LY333328 glycopeptide resistance on Enterococcus faecalis JH2-2 (MIC = 2 microg/ml). The two remaining plasmids conferred resistance to the drug (MIC, 8 microg/ml). The vanB gene cluster did not confer resistance to LY333328, since this antibiotic was not an inducer. Mutations in the vanS(B) sensor gene that al...
