Actinomycosis, caused by Actinomyces israelii, less frequent by Actinomyces odontolyticus. (Schaalia odontolytica)
Taxonomy
Family: Actinomycetaceae,
Natural habitats
As with all other actinomycotic diseases, A. odontolyticus (Schaalia odontolytica) is an endogenous infection arising from the mucous membranes
Clinical significance
Clinical disease in patients with A. odontolyticus (Schaalia odontolytica) closely resembles disease caused by A. israelii and other actinomyces species.
Infections by A. odontolyticus (Schaalia odontolytica) primarily involve the cervicofacial regions, the chest, abdomen, and pelvis with rare involvement of the central nervous system, bones, and joints

Gram-positive rods,
diphtheroid and may be arranged in palisades or
thin filamental and pleomorphic, which are 0.4–1.0 μm wide.
The filaments may be up to 50 μm in length with true branching.
Facultative anaerobic
On blood agar, colonies are small, irregular, whitish and smooth to slightly granular and show a dark red pigment when mature (2–14 days).
This pigmentation is most obvious when the cultures are left standing in air at room temperature after primary anaerobic isolation.
