catarrhalis) in the family Moraxellaceae, or to its own genus, Branhamella, in the family Branhamaceae. Currently known virulence factors include OMPs, LOS, and metabolic pathways, which are involved in adhesion, invasion, biofilm formation, modulation of the host immune system, and acquisition of nutrients. For reference, the major virulence factors currently known to be associated with M. catarrhalis pathogenesis are summarized in Table 1.

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.

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 Introduction. Moraxella catarrhalis is classified with the genera Neisseria, Moraxella, Kingella, and Acinetobacter in the family Neisseriaceae.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. Currently known virulence factors include OMPs, LOS, and metabolic pathways, which are involved in adhesion, invasion, biofilm formation, modulation of the host immune system, and acquisition of nutrients. For reference, the major virulence factors currently known to be associated with M. catarrhalis pathogenesis are summarized in Table 1.
