Characterization of vancomycin resistance in Enterococcus faecium and Enterococcus faecalis.
Vancomycin resistance in Enterococcus faecium 180, a clinical isolate from England, was studied. Resistance to vancomycin was transferable by conjugation to other enterococci. Expression of resistance was inducible and coincided with the appearance of a new membrane protein.
متن کاملVanD-type vancomycin-resistant Enterococcus faecium and Enterococcus faecalis.
Enterococcus faecium clinical isolates A902 and BM4538, which were resistant to relatively high levels of vancomycin (128 and 64 microg/ml, respectively) and to low levels of teicoplanin (4 microg/ml), and Enterococcus faecalis clinical isolates BM4539 and BM4540, which were resistant to moderate levels of vancomycin (16 microg/ml) and susceptible to teicoplanin (0.25 microg/ml), were studied. ...
متن کاملMechanism of resistance to vancomycin in Enterococcus faecium D366 and Enterococcus faecalis A256.
The role of the glycopeptide-inducible proteins of Enterococcus faecium D366 (39.5 kilodaltons) and Enterococcus faecalis A256 (39 kilodaltons) in the mechanism of resistance to vancomycin and teicoplanin was examined. Crude cell walls from noninduced cells or from induced cells treated with sodium dodecyl sulfate to remove the inducible proteins were shown to bind vancomycin, in contrast to ce...

متن کاملPresence of virulence factors in Enterococcus faecalis and Enterococcus faecium susceptible and resistant to vancomycin
Despite the increasing importance of Enterococcus as opportunistic pathogens, their virulence factors are still poorly understood. This study determines the frequency of virulence factors in clinical and commensal Enterococcus isolates from inpatients in Porto Alegre, Brazil. Fifty Enterococcus isolates were analysed and the presence of the gelE, asa1 and esp genes was determined. Gelatinase ac...
