how does moraxella differ from neisseria?

MoraxellaWill not utilize carbohydrates
Grow on BA
Colonies on the outer zone of
inhibition around penicillin
(elongated forms)

24

nonmotile
Free living in soil & water

Moraxella

25

Gram negative diplococci

Moraxella

26

Normal flora –
mucous membranes, skin, saliva
BA – small, pinpoint, nonpigmented colonies
Grows poorly or not all
on MAC

Moraxella

27

how does moraxella differ from acinetobacter?

moraxella is both catalase and oxidase positive
nonsaccharolytic

28
