Transferable, plasmid-mediated vanB-type glycopeptide resistance in Enterococcus faecium.
An approximately 60-kb transferable, vanB-carrying plasmid has been identified in a clinical Enterococcus faecium strain. A similar plasmid has been observed in an unrelated E. faecium strain, suggesting that plasmid transfer of vanB operons occurs in nature and plays a role in the dissemination of VanB-type resistance among strains of E. faecium.
متن کاملPeptidoglycan structure of Enterococcus faecium expressing vancomycin resistance of the VanB type.
Resistance to glycopeptide antibiotics in enterococci is due to the synthesis of UDP-MurNAc-tetrapeptide-D-lactate (where Mur is muramic acid) replacing the normal UDP-MurNAc-pentapeptide precursor. The peptidoglycan structures of an inducible VanB-type glycopeptide-resistant Enterococcus faecium, D366, and its constitutively resistant derivative, MT9, were determined. Using HPLC, 17 muropeptid...
متن کاملCharacterization 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 کاملCooperating Commensals Restore Colonization Resistance to Vancomycin-Resistant Enterococcus faecium.
Antibiotic-mediated microbiota destruction and the consequent loss of colonization resistance can result in intestinal domination with vancomycin-resistant Enterococcus (VRE), leading to bloodstream infection in hospitalized patients. Clearance of VRE remains a challenging goal that, if achieved, would reduce systemic VRE infections and patient-to-patient transmission. Although obligate anaerob...
متن کاملA sustained hospital outbreak of vancomycin-resistant Enterococcus faecium bacteremia due to emergence of vanB E. faecium sequence type 203.
BACKGROUND A significant increase in the rate of vancomycin-resistant Enterococcus faecium (VREfm) bacteremia at our health service, despite improved infection control, prompted us to investigate the cause. METHODS E. faecium bacteremia (including VREfm) over a 12-year period (1998-2009) was investigated using multilocus sequence typing, antibiotic and antiseptic susceptibility profiles, opti...
