This was confirmed by the report of 50-71% identity at the amino acid level between OMP B1 and six TbpB proteins (Luke et al., 1999).

Complement resistance in B. catarrhalis is associated with illness and may hence be considered a virulence factor. Purpose of review: Moraxella catarrhalis is an emerging human-specific pathogen responsible for upper and lower respiratory tract infections. Understanding the events in the complex pathogenesis and underlying mechanisms during M. catarrhalis infection is a key to the development of novel therapeutics and vaccines. Genomic and Metabolic Studies 1687 Virulence Factors 1690 Immune Response and Vaccine Development 1693 Conclusion 1693 References 1693 In the late 1960s, reports of the isolation of N. catarrhalis as a pathogen re- emerged (Coffey et al., 1967; Feign et al., 1969) and these continued to increase during the 1970s.

Branhamella catarrhalis virulence factors

The complement system is an important innate defence mechanism, and the ability to resist complement-mediated killing is considered a key virulence trait of the respiratory tract pathogen M. catarrhalis.

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. complement resistance.

Nosocomial infections by this organism are also evident (Wright et al., 1990). 1.4 Virulence factors As Moraxella (Branhamella) catarrhalis becomes more widely accepted as a pathogen, it is important to begin to identify potential virulence factors of Since M. catarrhalis has been considered a harmless commensal bacterium for a long time, there is relatively little cognition about pathogenicity characteristics and its virulence factors. Generally, the pathogenicity of this bacterium, like other microorganisms, depends on the ability to escape from the host defense mechanisms and binding to cellular and mucus layer, as well ( 4 ).
