Actinomycetaceae, Genus Actinomyces, Actinomyces oricola Hall, Collins, Hutson, Inganas, Falsen and Duerden, 2003.
Species description is based on a single isolate.
Gram-positive rods; branching and filaments forms may occur. Non-motile.
Colonies are pinpoint, white, breadcrumb-like, non-haemolytic on Fastidious
Anaerobe Agar with 5% horse blood after 2 days of anaerobic incubation. Facultative
anaerobic but grows best under anaerobic conditions. Grows at 37 ºC.
Isolated from a human dental abscess; habitat is unknown.
Isolated from human dental abscess.
