VanD and vanG-like gene clusters in a Ruminococcus species isolated from human bowel flora.

ABSTRACT: A vancomycin-resistant, anaerobic, gram-positive coccus containing the vanD and vanG-like genes (strain CCRI-16110) was isolated from a human fecal specimen during a hospital surveillance program to detect carriers of vancomycin-resistant enterococci. Comparison of the 16S rRNA gene sequence of strain CCRI-16110 with databases revealed a potentially novel Ruminococcus species that was most similar (<94% identity) to Clostridium and Ruminococcus species. Strain CCRI-16110 was highly resistant to vancomycin and teicoplanin (MICs of >256 microg/ml). The complete DNA sequence of the vanD cluster was most similar (98.2% identity) to that of Enterococcus faecium BM4339, containing the vanD1 allele. An intD gene with 99% identity with that of this E. faecium strain was found to be associated with
