Rossau et al. 1987. Included in CDC group IVe.
Gram-negative small rods, mostly not exceeding 1 μm and often occurring in pairs;
they lack the typical plumpness of moraxellae. Nonspore-forming. Noncapsulated.
Some strains are motile by means of long peritrichous flagella.
Colonies on blood agar develop slowly and are more overtly white than those of all
recognized species of Moraxella. No pigments and no odor are produced.
Nonhemolytic.
Aerobe. Grows at 30-37 ºC, but not at 42 ºC. Grows on p-hydroxybenzoate as a carbon
source. Grows in the presence of up to 3% NaCl, and on Drigalski agar.
Isolated from human urine. Usually resistant to penicillin.
Undetermined.
