''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. 〔http://www.oralgen.lanl.gov/oralgen/bacteria/pintnew/〕 ''P. intermedia'' use steroids as growth factors, so their numbers are higher in pregnant women. It has also been isolated from women with bacterial vaginosis. ==See also== * Oral microbiology * Periodontitis * List of bacterial vaginosis microbiota 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Prevotella intermedia」の詳細全文を読む スポンサード リンク
