SUMMARY Moraxella catarrhalis (formerly known as Branhamella catarrhalis) has emerged as a significant bacterial pathogen of humans over the past two decades. During this period, microbiological and molecular diagnostic techniques have been developed and improved for M. catarrhalis, allowing the adequate determination and taxonomic positioning of this pathogen.

Old synonyms: Mikrokkokus catarrhalis (sic) Frosch and Kolle in Flügge 1896, Neisseria catarrhalis (Frosch and Kolle 1896) Holland 1920. 2015-02-08 As far as Branhamella catarrhalis is concerned, identification by standard biochemical methods is time consuming while use of the rapid tests can be inaccurate. Also noticed by Knapp (mentioned above), the species that are the most difficult to distinguish from N. gonorrhoeae by biochemical characteristics are N. cinerea, B. catarrhalis and K. denitrificans. Micrococcus catarrhalis, Neisseria catarrhalis and later Branhamella catarrhalis was first isolated in 1896 and was thought to be a harmless Biochemical tests were carried out for identification of Morzr.rplla curur.r-llalis. Catalase and oxidase activity was determined following The Moraxella genus currently contains at least 14 different species, including M. catarrhalis, M. bovis, M. lacunata, M. osloensis, M. nonliquefaciens, M. atlantae, M. lincolnii, M. ovis, M. caviae, M. canis, M. equi, M. cuniculi, M. caprae and M. boevreii, which colonize both humans and animals.The genus is under constant revision, with recent taxonomic restructuring placing the bacterial ventional biochemical tests or novel chromogenic sub-strates.
