The Moraxellaceae are a family of gamma protobacteria. Some species are pathogens in humans. Moraxella catarrhalis can cause bronchitis , sinus infections and otitis media. Acinetobacter baumannii can u. a. Cause wound infections and pneumonia. Moraxella bovis can cause the so-called pink eye , a horn and conjunctivitis, in cattle . Other species occur in the water or soil.
The family's eponymous genus ( type genus ) Moraxella is named after the Swiss doctor Victor Morax (1866–1935), who discovered Moraxella lacunata , a bacterium responsible for inflammation of the conjunctiva.
features
The species of the Moraxellaceae are rod-shaped or cocci-shaped. Like all proteobacteria, they are gram negative . You are catalase positive. Within the family there are also cold-loving ( psychrophilic ) species (genus Psychrobacter ). Some species can form capsules. They are aerobic , that is, they rely on oxygen, and are chemoheterotrophic . Flagella are usually not present, but some species can move by leaps and bounds by a "spring mechanism ", the so-called twitching motility . This is created by special pili . Examples are Moraxella bovis , Moraxella nonliquefaciens, and various types of Acinetobacter .
