Moraxella (Branhamella) catarrhalis. Moraxella catarrhalis (MC) is the third ranking commensal inhabitant of the upper respiratory tract (Chung et al., 1994) capable of inducing otitis media, sinusitis, conjunctivitis, and bronchitis in pediatric populations (Bakaletz et al., 1995; Luke et al., 2007).

About 1 to 5% of healthy adults have upper respiratory tract colonization. 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.

An isolate was almost certainly not a gonococcus if it gave a negative superoxol test result, as all but one of 596 available gonococci gave positive test results.

The Gen-Probe Accuprobe test targets rRNA after lysis of bacteria; the rRNA is detected using a single-strand chemiluminescent DNA probe. The hybrids are then detected in a luminometer.
