Prevotella spp. are obligate anaerobic, Gram-negative rod-shaped bacteria belonging to the Prevotellaceae family. The genus comprises approximately 30 species. Prevotella spp. often colonise the human oral, intestinal and urogenital floras. When the mucous membrane is stressed or injured, the facultative pathogens can enter the body and thus trigger infections.
Prevotella spp. may cause lung, abdomen or brain abscesses. Furthermore, the bacteria can elicit dental, lower abdomen and wound infections.
Transmission occurs via direct or indirect contact with infected persons.
