Phylum Actinobacteria, Class Actinobacteria, Subclass Actibacteridae, Order Actynomycetales, Suborder Actinomycinae, Family
Actinomycetaceae, Genus Actinomyces, Actinomyces nasicola Hall, Collins, Lawson, Falsen and Duerden, 2003.
Species description is based on a single isolate.
Gram-positive, diphtheroid rods; branching and coccoid forms occur. Non-acid-fast.
Colonies are pinpoint, convex, white or gray, opaque, shiny, on fastidious anaerobe
agar after 2 days. Facultative anaerobic but grew better under anaerobic conditions.
Isolated from a human antrum aspirate; habitat is unknown.
