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.

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.

catarrhalis produces and secretes beta-lactamase containing outer-membrane vesicles that can function as an extracellular delivery system of beta-lactam resistance that promotes the survival of otherwise beta-lactam sensitive bacteria in the vicinity of M. catarrhalis.

The size of the organism varies; it is often larger than the meningococcus or gonococcus. The flat sides of the organism abut against each other. M. catarrhalis can be treated with antibiotics, but it is commonly resistant to penicillin, ampicillin, and amoxicillin.. Current research priorities involve trying to find a suitable vaccine for this genotypically diverse organism, as well as determining factors involved with virulence, e.g.
