Genetic characteristics of VanA-type vancomycin-resistant Enterococcus faecalis and Enterococcus faecium in Cuba
VanA-type vancomycin-resistant enterococci isolates from bloodstream infections in Cuba were genetically characterized. Enterococcus faecalis isolates were assigned to sequence type (ST) 28, closely related to Eastern Europe, while Enterococcus faecium belonged to ST262, ST656 and ST1349, and showed different genetic profiles.
متن کاملHighly conjugative pMG1-like plasmids carrying Tn1546-like transposons that encode vancomycin resistance in Enterococcus faecium.
A total of 12 VanA-type vancomycin-resistant enterococci, consisting of 10 Enterococcus faecium isolates and two Enterococcus avium isolates, were examined in detail. The vancomycin resistance conjugative plasmids pHTalpha (65.9 kbp), pHTbeta (63.7 kbp), and pHTgamma (66.5 kbp) were isolated from each of three different E. faecium strains. The plasmids transferred highly efficiently between ent...
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 ...
متن کاملEmergence of vanA vancomycin-resistant Enterococcus faecium in a hospital in Porto Alegre, South Brazil.
INTRODUCTION In Porto Alegre (South Brazil), since the first VRE isolation in 2000 until the middle of the last decade, the epidemiology of enterococcal infections presented the peculiarity that, as opposed to other regions of the country, almost all VRE were E. faecalis. The aim of this study was to investigate the microbiological and epidemiological characteristics of a VRE outbreak that occu...
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...
