The incidence of the disease is highest in the summer months. The ability of M. catarrhalis to resist complement-mediated lysis is considered to be an important virulence factor of this organism [ 17, 18 ]. Similar to the case in Neisseria species, complement resistance of M. catarrhalis is likely to be multifactorial, but the molecular basis is only partially understood. Recently, we showed that complement resistance is an important virulence factor of Moraxella (Branhamella) catarrhalis. Our study used a serum bactericidal assay to determine complement resistance Complement resistance is a virulence factor of Branhamella (Moraxella) catarrhalis.
