Silencing of glycopeptide resistance in Enterococcus faecalis BM4405 by novobiocin.
Enterococcus faecalis BM4405-1, a susceptible derivative of the VanE-type vancomycin-resistant E. faecalis strain BM4405, was obtained after growth in the presence of novobiocin, an inhibitor of the GyrB subunit of DNA gyrase. In contrast to findings for BM4405, UDP-MurNAc-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala (pentapeptide[D-Ala]) was the only peptidoglycan precursor found in BM4405-1, and no Va...
متن کاملVanE, a new type of acquired glycopeptide resistance in Enterococcus faecalis BM4405.
Enterococcus faecalis BM4405 was resistant to low levels of vancomycin (MIC, 16 microg/ml) and was susceptible to teicoplanin (MIC, 0.5 microg/ml). No PCR product was obtained when the total DNA of this clinical isolate was used as a template with primers specific for glycopeptide resistance genes vanA, vanB, vanC, and vanD. However, a 604-bp PCR fragment was obtained when V1 and V2 degenerate ...
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 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 کاملAntibiogram analysis and tracking of the virulence-related genes in Enterococcus faecalis isolates
Background and Aim: Enterococcus species are opportunistic pathogens and their pathogenicity seems to be related to the presence of a number of pathogenicity genes. Since donkey’s milk is a new non-allergenic source of nutrition, this study was performed to assess the antibiogram and detection of pathogenicity genes in some Enterococcus faecalis isolates from donkey’s milk. Materials and Method...
