Animal models of M. catarrhalis AOM and human studies have suggested a weaker local immune response and fewer structural changes compared with AOM caused by S. pneumoniae or H. influenzae [ 11-13 ]. The prevalence of M. catarrhalis colonization depends on age. 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. M. catarrhalis is a human pathogen with an affinity for the human upper respiratory tract.

However, since the late 1970s it has been clear that M. catarrhalis is an important and common human respiratory tract pathogen. M. catarrhalis has an interesting and checkered taxonomic history. M. catarrhalis AOM is usually considered a relatively less virulent pathogen [10], but the clinical features of AOM caused by M. catarrhalis have not been described in detail.

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. Moraxella catarrhalis is a type of bacteria common in young children. It can often be harmless. Those at risk of infection complications are people with underlying health conditions or a weakened M. catarrhalis is a recognized pathogen in pediatric upper respiratory infections such as otitis media, sinusitis, and pharyngitis.

The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella. Moraxella catarrhalis is a gram-negative, aerobic, oxidase-positive diplococcus that was first described in 1896. The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella. Usually, when adults with COPD contract M catarrhalis infection, their organism is efficiently cleared from the respiratory tract after a relatively short period (mean time, 34 days). Patients then develop strain-specific protection against re exposure to the same bacterial strain. The majority of patients develope serum immunoglobulin M. catarrhalis and E. coli cells were used to prepare whole-cell lysates as de-scribed previously (37).

It is also the cause of upper respiratory tract infections, and sometimes pneumonia. Moraxella is common in the winter months and puts babies and children at increased risk for frequent ear infections. In the past, M. catarrhalis was considered a nonpathogenic member of the resident flora of the nasopharynx. It was one of the species belonging to the so-called nongonococcal, nonmeningococcal neisseriae, considered to be members of the normal flora. The name of the species has caused considerable confusion. M. catarrhalis AOM is usually considered a relatively less virulent pathogen [10], but the clinical features of AOM caused by M. catarrhalis have not been described in detail.
