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).]]

The oral mucosa is heavily colonized with bacteria, and bacteria are known to invade the epithelial cells lining the cheeks (Rudney et al., 2005).]]
