High frequency distribution of heterogeneous vancomycin resistant Enterococcous faecium (VREfm) in Iranian hospitals
BACKGROUND Enterococcus faecium is a multi-resistant nosocomial pathogen causing infection in debilitated patients. Vancomycin-resistant enterococcus faecium (VREfm) are a major concern and increased dramatically worldwide especially in hospitals environment. The current study focused on determining the high prevalence and distribution patterns of antibiotic resistance and also its genetic link...
متن کاملincrease in prevalence of vancomycin resistant isolates of enterococcous faecium at labbafinejad hospital
background vancomycin resistant isolates of enterococcous faecium (vre) have previously been reported from tehran hospitals. however, little data were available on the genetic heterogeneity of vre isolates among the iranian population. therefore the emergence of infections with the new clones of vre needs to be investigated. the drug resistance surveillance program at labbafinejad hospital has ...
متن کاملHigh-Level Fosfomycin Resistance in Vancomycin-Resistant Enterococcus faecium
Of 890 vancomycin-resistant Enterococcus faecium isolates obtained by rectal screening from patients in Pittsburgh, Pennsylvania, USA, 4 had MICs >1,024 μg/mL for fosfomycin. These isolates had a Cys119Asp substitution in the active site of UDP-N-acetylglucosamine enolpyruvyl transferase. This substitution increased the fosfomycin MIC >4-fold and rendered this drug inactive in biochemical assays.
متن کاملVancomycin-resistant Enterococcus faecium colonization in children.
Nosocomial vancomycin-resistant Enterococcus (VRE) infections have been described in only small numbers of pediatric patients. In none of these studies were multivariate analyses performed to assess which factors were independent risk factors in these patients. In the present cohort study of patients admitted to our hematology/oncology unit, surveillance cultures revealed a colonization rate of...
متن کاملColonial variation in vancomycin resistant Enterococcus faecium.
Vancomycin resistant enterococci are increasingly being isolated from inpatients. This report describes the colonial variation present in most isolates of vancomycin resistant Enterococcus faecium obtained at this hospital. Colonial variants within the same culture were indistinguishable by antimicrobial susceptibility, biochemical reactions, and ribotyping. Failure to appreciate this colonial ...
