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 dental abscesses, where obligate anaerobes predominate.

Prevotella intermedia is thought to be more prevalent in patients with noma.

Prevotella intermedia use steroid hormones as growth factors, so their numbers are higher in pregnant women.{{citation needed|date=May 2015}} It has also been isolated from women with bacterial vaginosis.{{cite journal | vauthors = Africa CW, Nel J, Stemmet M | title = Anaerobes and bacterial vaginosis in pregnancy: virulence factors contributing to vaginal colonisation | journal = International Journal of Environmental Research and Public Health | volume = 11 | issue = 7 | pages = 6979–7000 | date = July 2014 | pmid = 25014248 | pmc = 4113856 | doi = 10.3390/ijerph110706979 | doi-access = free }}
