Epidemic and Nonepidemic Multidrug-Resistant Enterococcus faecium
The epidemiology of vancomycin-resistant Entero- coccus faecium (VREF) in Europe is characterized by a large community reservoir. In contrast, nosocomial outbreaks and infections (without a community reservoir) characterize VREF in the United States. Previous studies demonstrated host-specific genogroups and a distinct genetic lineage of VREF associated with hospital outbreaks, characterized by...
متن کاملLarge clonal outbreak of multidrug-resistant CC17 ST17 Enterococcus faecium containing Tn5382 in a Spanish hospital.
OBJECTIVES A large clonal outbreak of multidrug-resistant CC17 ST17 Enterococcus faecium containing Tn5382 in a hospital in the north of Spain is described. METHODS We characterized vancomycin-resistant E. faecium isolates from 10 infected and 40 colonized inpatients from a single hospital by PFGE, multiple-locus variable-number tandem-repeat analysis (MLVA) and multilocus sequence typing (ML...
متن کاملMolecular characterization of glycopeptide-resistant Enterococcus faecium isolates from Portuguese hospitals.
Fifty-one pulsed-field gel electrophoresis types and 17 Tn1546 variants were identified among 101 Enterococcus faecium isolates recovered in three distant Portuguese hospitals. Intra- and interhospital dissemination of specific strains and Tn1546 types was detected, which might largely contribute to the endemicity of vancomycin-resistant E. faecium in Portuguese hospitals, as happened previousl...
متن کاملCentromere anatomy in the multidrug-resistant pathogen Enterococcus faecium.
Multidrug-resistant variants of the opportunistic human pathogen Enterococcus have recently emerged as leading agents of nosocomial infection. The acquisition of plasmid-borne resistance genes is a driving force in antibiotic-resistance evolution in enterococci. The segregation locus of a high-level gentamicin-resistance plasmid, pGENT, in Enterococcus faecium was identified and dissected. This...
متن کاملMolecular characterization of vancomycin-resistant Enterococcus faecium isolates from Bermuda
Molecular characteristics of vancomycin resistant enterococci isolates from Bermuda Island is currently unknown. This study was conducted to investigate phenotypic and genotypic characteristics of VRE isolates from Bermuda Island using the chromogenic agar, E-tests, polymerase chain reaction (PCR), pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Eighteen E. faeciu...
