anA glycopeptide resistance is characterized by acquired nducible resistance to both vancomycin and teicoplanin, hereas the VanB phenotype is characterized by variable evels of resistance to vancomycin but susceptibility to eicoplanin.1 Here we report a vancomycin-resistant Enterooccus faecium (VREFm) strain with VanB phenotype-vanA enotype incongruence. In the course of antimicrobial susceptib...

Enterococci are part of the normal intestinal flora of humans and animals but have also emerged as important pathogens responsible for serious infections in hospital and community acquired infections. The aim of this study was to investigate the prevalence of Enterococcus with their antimicrobial susceptibility pattern from patients of Mymensingh Medical College Hospital, Bangladesh during the ...

Enterococci are a major cause of health care-associated infections and account for approximately 10% of all bacteremias globally. The aim of this study was to determine the proportion of enterococcal bacteremia isolates in Australia that are antimicrobial resistant, with particular emphasis on susceptibility to ampicillin and the glycopeptides, and to characterize the molecular epidemiology of ...

OBJECTIVE To demonstrate that nosocomial transmission of vancomycin-resistant enterococci (VRE) can be terminated and endemicity prevented despite widespread dissemination of an epidemic strain in a large tertiary-care referral hospital. INTERVENTIONS Two months after the index case was detected in the intensive care unit, 68 patients became either infected or colonized with an epidemic strai...

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...

VanD-type resistance to glycopeptides in Enterococcus faecium BM4339 is due to constitutive synthesis of D-alanyl-D-lactate-terminating peptidoglycan precursors (B. Périchon, P. Reynolds, and P. Courvalin, Antimicrob. Agents Chemother. 41:2016-2018, 1997). The sequence of a 5,780-bp fragment was determined and revealed six open reading frames. The 3' distal part encoded the VanHD dehydrogenase,...

Enterococcus faecium, E. durans and faecalis species were isolated identified from traditional Urfa cheese samples which produced unpasteurized raw milk. The enterococcal load of the was between 4.4-5.6 log cfu g−1. High-level tetracycline, streptomycin, erythromycin, gentamycin, penicillin resistance determined in isolates. Multiple antibiotic also (20.4%) faecium (16.3%) strains. 36.7% isolat...
