Moraxella

 [mo″-rak-sel´ah]
a genus of gram-negative, aerobic bacteria found as parasites on the mucous membranes of mammals. There are two subgenera: M. (Moraxella), occurring as rods, and M. (Branhamella), occurring as cocci. M. (Branhamella) catarrha´lis occasionally causes respiratory disease; M. (Moraxella) lacuna´ta causes conjunctivitis and corneal infections.

Moraxella

(mōr'ak-sel'ă),
A genus of obligately aerobic nonmotile bacteria (family Neisseriaceae) containing gram-negative coccoids or short rods that usually occur in pairs. They do not produce acid from carbohydrates, are oxidase positive, penicillin susceptible, and infect the mucous membranes of humans and other mammals. The type species is Moraxella lacunata.

Moraxella

/Mo·rax·el·la/ (mo-rak-sel´ah) a genus of bacteria (family Neisseriaceae), made up of gram-negative, short, aerobic, nonpigmented organisms found as parasites and pathogens on the mucous membranes of mammals; it includes two subgenera: M. (Moraxella) and M. (Branhamella). M. (Branhamel´la) catarrha´lis is a normal inhabitant of the human nasal cavity and nasopharynx, occasionally causing otitis media or respiratory disease. M. (Moraxel´la) lacuna´ta causes conjunctivitis and corneal infections.

Moraxella

a genus of the Neisseriaceae family of gram-negative nonmotile cocci. They are found as pathogens and parasites on the mucous membranes of warm-blooded animals.
