16S rRNA accession # | IMG Genome ID:: | [[]] |
Family | Family::Prevotellaceae | [[]] |
Genus | Genus::Prevotella | Phylogenetic analysis of the 16S rRNA gene sequence of strain T05-04T revealed this organism to belong to the genus Prevotella (Fig. 2) |
Species | Species::histicola | [[Prevotella histicola [his.ti9co.la. N.L. masc. n. histus (from Gr. histos) tissue; L. suffix -cola (from incola) inhabitant; N.L. fem./masc. n. histicola inhabitant of tissue].]] |
Strain | Strain::T05-04 | The type strain of Prevotella histicola is T05-04T (5DSM 19854T5CCUG 55407T). |
Genetic characteristics | ||
Genome size: | Genome size::0.7 X 0.8-3.0 um | Gram-negative bacilli that are 0.760.8–3.0 um in size. |
%G+C: | Percent size::43 mol% | The G+C content of the DNA of the type strain is 43 mol%. |

Pigments | Pigments::variably | [[The results of the phenotypic tests can be viewed in table format as supplementary data (Supplementary Table S1) in IJSEM Online. Strains T05-04T, N12-20 and N19-30 were obligately anaerobic, non-motile, variably pigmenting, Gram-negative bacilli that were 0.7 mm wide by 0.8– 3.0 mm long (and occasionally up to 5 mm long). After 3 days incubation on FAA plates, colonies were 1.5– 2.0 mm in diameter, circular, entire, convex, cream and opaque with a solid non-translucent internal appearance when viewed under a plate microscope (Fig. 1a). Upon further incubation, strain N19-30 developed a deep reddish-brown pigment in the centre of the colony, forming a bull’s-eye appearance (Fig. 1b). Strains T05- 04T and N12-20 remained unpigmented even after 2 weeks incubation on FAA with 5 % rabbit blood. However, in the presence of a metronidazole disc (5 mg; Oxoid), strains T05-04T and N12-20 formed some black-pigmented colonies around the edge of the zone of growth inhibition on FAA (Fig. 1c). When these pigmented colonies were subcultured they retained their black pigmentation even in the absence of metronidazole (Fig. 1d).]] |
