Pasteurellaceae form a family of the Proteobacteria and are the only member of the order Pasteurellales . They are gram-negative , rod-shaped or cocci-shaped bacteria, which differ from the Enterobacteriaceae in the presence of oxidase and from most similar bacteria in the absence of flagella . Some species are pleomorphic and change their cell shape over time, in older cultures the formation of filaments (cell threads) can often be observed. In this family there are some species pathogenic to humans, such as B. Haemophilus influenzae .
ecology
The different species are usually obligate commensals ("peaceful roommates") or parasites of mammals and birds. They mostly colonize mucous membranes in the digestive tract, in the respiratory organs or in the genital tract.
There are aerobic , microaerobic and facultative anaerobic species. The facultative species can live with complete oxygen exclusion, the microaerobes show the best growth rates with low oxygen levels in the environment. They eat chemoorganotrophically , under anaerobic conditions the metabolic pathway is fermentation , otherwise breathing takes place.
