Veillonellaceae

Veil·lo·nel·la·ce·ae

(vā'yō-nĕ-lā'sē-ē), A family of nonmotile, nonsporeforming, anaerobic bacteria (order Eubacteriales) containing gram-negative (with a tendency to resist decolorization) cocci that vary in diameter from small (0.3-0.5 mcm) to large (2.5 mcm). Characteristically, they occur in pairs; single cells, masses, or chains may also occur, but the chains may show gaps illustrating the basic diplococcal arrangement. These organisms are chemoorganotrophic; they may or may not ferment carbohydrates; they are parasites of homothermic animals such as humans, ruminants, rodents, and pigs, and are primarily found in the alimentary tract. The type genus is Veillonella.
