Species: P. intermedia

Prevotella intermedia (formerly Bacteroides intermedius) is a Gram-negative, obligate anaerobic pathogenic bacterium involved in periodontal infections, including gingivitis and periodontitis, and often found in acute necrotizing ulcerative gingivitis . It is commonly isolated from dentoalveolar abscesses, where obligate anaerobes predominate. P. intermedia is thought to be more prevalent in patients with noma known also as cancrum oris. [1]

P. intermedia use steroids as growth factors, so their numbers are higher in pregnant women.[citation needed] It has also been isolated from women with bacterial vaginosis.[2]
