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 کاملVanG-type vancomycin-resistant Enterococcus faecalis strains isolated in Canada.
Enterococcus faecalis G1-0247 (vancomycin MIC, 16 microg/ml) was found to harbor a vanG operon 99% identical to the vanG operon in E. faecalis BM4518. E. faecalis N03-0233 (vancomycin MIC, 16 microg/ml) was found to harbor a novel vanG operon, vanG2, on an element in a different chromosomal location than the vanG-harboring elements in G1-0247 and BM4518.
متن کاملCharacterization of monolaurin resistance in Enterococcus faecalis.
There is increasing concern regarding the presence of vancomycin-resistant enterococci in domestically farmed animals, which may act as reservoirs and vehicles of transmission for drug-resistant enterococci to humans, resulting in serious infections. In order to assess the potential for the use of monolaurin as a food preservative, it is important to understand both its target and potential mec...

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...
