A novel strictly anaerobic, vancomycin-resistant, Gram-positive coccus (strain CCRI-16110) was isolated from a human faecal specimen. This strain was characterized using morphological, biochemical and molecular taxonomic methods. The organism was unable to hydrolyse aesculin and failed to produce acid from cellobiose, -lactose and -raffinose. Acetic acid was the sole product of glucose fermentation by the organism. On the basis of 16S rRNA and gene sequence comparison, strain CCRI-16110 was most closely related to species of the genus and formed a hitherto unknown sublineage within the rRNA cluster of organisms (cluster XIVa). Based on phenotypic and phylogenetic evidence, a novel species, sp. nov., is proposed. The type strain is CCRI-16110 (=NML 060141 =CCUG 54292 =JCM 14987).
