Veillonella parvulaRANK: Species
TAXONOMY: Terrabacteria group -> Firmicutes -> Negativicutes -> Selenomonadales -> Veillonellaceae -> Veillonella -> Veillonella parvula
Type species of the genus. Phylogentically indistinguishable to V. dispar. Nonhemolytic on Blood agar. Distinctive colony (1-3 mm) morphology, e.g., lens-, diamond- or heart-shaped, when grown on lactate agar media. Smooth, entire and grayish white in appearance. Commonly detected in the human oral cavity and intestinal tract. Prevalent on all oral surfaces  and in supragingival and subgingival plaque [4,5,6]Veillonella parvula tend to be more prevalent in sites without disease, however it has been associated with discitis , tonsillitis, spinal osteomyelitis, sepsis, endodontic lesions , and coronary heart disease Identified as a constituent of the oral microbiome by Human Oral Microbiome Database.
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]
