Morphology Eikenella corrodens
CELLULAR  
Staining Gram-negative
Morphology Straight rods, 0.3-0.4 x 1.5-4.0 um, unbranched, with rounded ends and a regular morphology. Short filaments are occasionally formed.
Motility Non-motile, possessing no flagella; however a "twitching motility" may occur on agar surfaces
Specialized structures Nonsporeforming.
Division  
COLONIAL  
Solid surface Colonies may appear to corrode the surface of the agar; noncorroding strains may also occur. Nonhemolytic; a slight greening of blood media around colonies may occur
