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

In addition, this organism causes a Introduction. Moraxella catarrhalis is classified with the genera Neisseria, Moraxella, Kingella, and Acinetobacter in the family Neisseriaceae.The taxonomic position of M. catarrhalis is currently being debated; it has been proposed that M. catarrhalis be assigned to the genus Moraxella (M. catarrhalis) in the family Moraxellaceae, or to its own genus, Branhamella, in the family Branhamaceae. Table 1 provides a list of traditional tests used to identify strains of N. gonorrhoeae. Detailed information on biochemical tests is in the menu at left and in Table 1. Table 1.

Thesuperoxol test is a simple and economical test which can be performed on colonies from primary culture plates. It can differentiate Bcatarrhalis from Nperflava, Npharyngis and several other non-pathogenic Neisseria spp (table).

Because this organism can be found at the same sites as pathogenic Neisseria spp. and shares some physiological and biochemical characteristics, it is important to have a Branhamella catarrhalis as a possible skin pathogen Branhamella catarrhalis as a possible skin pathogen ADRIAANS, B.; NOBLE, W. 1987-09-01 00:00:00 Summary Branhamella catarrhalis is usually regarded as a nonpathogenic commensal of the upper respiratory tract. However, in the last few years, several reports have appeared describing the organism as a potential pathogen.'"-^ We describe a There is provided by the present invention, a method for detecting the presence of Branhamella catarrhalis, said method comprising, depositing and fixing on an inert support a sample containing DNA fragments in substantially single stranded form, contacting said fixed single stranded genetic material with a labelled probe consisting of a fragment of B. catarrhalis chromosomal DNA, identified 2020-06-06 Abstract. During the past decade, the taxonomy of Branhamella and Neisseria species has been extensively revised and expanded. Inturn, this has led to the renaming of certain species, as well as the addition of new ones. As the tools for defining bacterial genus and species relatedness become more refined, bacterial nomenclature necessarily becomes more complex.
