Gram-negative rods (0.9-1.6–1.5 x 1.5–2.5 μm), becoming spherical in the stationary phase of growth. Grouped in pairs or chains. Aerobic. Nonmotile but may display “twitching motility”. Optimum growth temperature 33-35 ºC; some can't grow at 37 ºC. Catalase positive. Oxidase negative. Nitrates are not reduced. Found mostly in water & soil |

|
Genus Moraxella (Branhamella) Lwoff 1939 (Catlin 1970) |
Gram-negative rods or cocci. The rods are often very short and plump, close to a coccus shape (1.0–1.5 x 1.5–2.5 μm). The cocci are usually smaller (0.6–1.0 μm. Aerobic, but some strains may grow weakly under anaerobic conditions. May be encapsulated. Nonmotile but surface-bound “twitching motility” has been observed. No pigment production. Oxidase and catalase are positive. Some species are human or animal pathogens. |
