High Prevalence of vanM in Vancomycin-Resistant Enterococcus faecium Isolates from Shanghai, China
The vanM gene was first found in a vancomycin-resistant Enterococcus faecium (VREm) isolate in Shanghai in 2006. In this study, we found that, in 70 VREm strains isolated in nine Shanghai hospitals from 2006 to 2014, vanM was more prevalent than the vanA gene (64.3% [45/70] versus 35.7% [25/70]). The vanM-type isolates showed similar antimicrobial susceptibility patterns with the vanA types. Th...
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 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 کاملVanD-type vancomycin-resistant Enterococcus faecium 10/96A.
VanD type Enterococcus faecium 10/96A is constitutively resistant to vancomycin and to low levels of teicoplanin by nearly exclusive synthesis of peptidoglycan precursors terminating in D-alanyl-D-lactate (L. M. Dalla Costa, P. E. Reynolds, H. A. Souza, D. C. Souza, M. F. Palepou, and N. Woodford, Antimicrob. Agents Chemother. 44:3444-3446, 2000). A G(184)S mutation adjacent to the serine invol...
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...
