Parvimonas micraRANK: SpeciesTAXONOMY: Terrabacteria group -> Firmicutes -> Tissierellia -> Tissierellales -> Peptoniphilaceae -> Parvimonas -> Parvimonas micra OVERVIEW: This species is known to be heterogeneous with micro-variation among 16S rRNA sequences, including between operons within strains and phenotypic variation including colonial appearance [1].Colonies on horse blood agar are around 1 mm in diameter, circular, entire, opaque white or translucent gray and may be smooth or rough after 4 days anaerobic incubation.Parvimonas micra is a commonly found oral species and is isolated from dental plaque and the tongue in health and a variety of oral disease associated microbiota including periodontitis, endodontic and dentoalveolar infections, pericoronitis and advanced dental caries.Has been isolated from most types of oral infection. Is a particularly frequent isolate from acute dentoalveolar infections where it is often a member of the 15-20 species consortium associated with the condition. Has also been isolated from clinical specimens obtained from infections at other body sites, primarily soft-tissue abscesses and bite wounds. These are primarily at sites above the diaphragm suggesting that the mouth is the primary habitat.Identified as a constituent of the oral microbiome by Human Oral Microbiome Database. Identified as constituent of vaginal microbiome. [PMID:23282177] This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072] |
