Heteroresistance to teicoplanin in Enterococcus faecium harboring the vanA gene.
Hospital-acquired infections caused by vancomycin-resistant enterococci (VRE) are increasing. The resistance of VRE to multiple antibiotics makes them clinically challenging. There are at least six phenotypes of VRE, including VanA, VanB, VanC, VanD, VanE, and VanG (2, 8). These phenotypes correspond with the genotypes vanA, vanB, vanC, vanD, vanE, and vanG. VanA and VanB phenotypes are common ...
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 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...
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 کاملHeat tolerance of vancomycin resistant Enterococcus faecium.
The heat tolerance of 27 Enterococcus faecium isolates in water was studied. Stationary phase cultures including vancomycin resistant and sensitive clinical and food isolates were exposed to heat at 60 degrees, 65 degrees, 71 degrees, and 80 degrees C for one, three, 10, and 30 minutes and the log10 reductions in bacterial counts were determined. Exposure at 71 degrees and 80 degrees C resulted...
