Morphology | Dermatophilus congolensis |
CELLULAR |
Staining | Gram-positive Not acid fast |
Morphology | Aerial mycelium develops in atmospheres containing added CO2. Substrate mycelium consists of long tapering filaments, branching laterally at right angles; septa formed in transverse and in horizontal and vertical longitudinal planes, giving rise to up to eight parallel rows of coccoid cells (spores), |
Motility | spores are motile by a tuft of flagella.. |
