Morphology | Oerskovia |
CELLULAR |
Staining | Gram-positive with part of the thallus becoming Gram-negative when grown anaerobically. |
Morphology | Extensively branching vegetative hyphae, about 0.5 um in diameter, growing on the surface of and penetrating into agar media, breaking up into rod-shaped, motile, flagellate elements. Growth appears coryneform to bacteroid in smears. Rods monotrichous when small and peritrichous when long No aerial mycelium formed |
