Gram-positive long rods, 0.8-1.2 x 2.1-8.6 µm, occurring singly or in pairs.
Colonies are cream, 0.46-0.68 mm in diameter after 3 days of anaerobic incubation
on MRS agar. Can grow at 15-46 ºC. Grows at pH 5.0-9.5. Facultative anaerobic.
Isolated from the intestine of wild mice (Mus musculus), Bohemia.
Susceptible to cephalosporines, macrolides, penicillin-derived antibiotics, and mupirocine. Resistant to aminoglycosides,
fluoroquinolones, sulfonamides, and metronidazole.
Undetermined.
