Nasopharyngeal colonization with M. catarrhalis is common throughout infancy, may be increased during winter months, and is a risk factor for acute otitis media; early colonization is a risk factor for recurrent otitis media. Moraxella catarrhalis formerly known as Micrococcus catarrhalis, Neisseria catarrhalis and later Branhamella catarrhalis was first isolated in 1896 and was thought to be a harmless normal flora of human upper respiratory tract for the subsequent 50 years. However only in the past decade or so its role as a disease causing Moraxella catarrhalis (antes conocida como Branhamella catarrhalis) es una bacteria gram negativa, aeróbica, oxidasa positiva con forma de diplococos que Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase- positive Nevertheless, some in the medical field continue to call these bacteria Branhamella catarrhalis.

m.catarrhalis identification, tests for the identification of Moraxella catarrhalis

Branhamella catarrhalis, previously named Neisseria catarrhalis was known as a saprophytic inhabitant of the human respiratory tract. The importance as a facultative pathogen has increased during the last years.

The size of the organism varies; it is often larger than the meningococcus or gonococcus. The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc). This tributyrin spot test helped in differentiating M. catarrhalis from other nonpathogenic Neisseria species that are generally found in the respiratory tract.
