Includes strains from Rothia dentocariosa genomovar II.
Gram-positive, coccoid, cocco-bacillary or filamentous cells. Non-spore-forming.
Non-motile. Non-acid-fast.
Young colonies are creamy white and smooth. Mature colonies are rough, dry, folded
and convex and adhere to the agar. Growth occurs on BHIA at 30 ºC. Aerobic.
Initially isolated from Russian space laboratory, Mir air sample.
Can colonize human oral cavity, but has also been identified in duodenal biopsy as a colonizer of the upper gastrointestinal tract.
Has been involved in endocarditis, abscesses, lung infection or neonatal sepsis.
