catarrhalis can be carried asymptomatically (known as carriage), but can also causes otitis media in children and lower respiratory tract infections in adults with chronic obstructive pulmonary disease (Verduin et al., 2002).

One of these virulence factors is the ability of M. catarrhalis to resist the action of complement (9, 12, 17, 20, 24-26). Recently, we showed that complement resistance is an important virulence factor of Moraxella (Branhamella) catarrhalis.

1990-05-14 · The lipopolysaccharide and outer membrane proteins of B. catarrhalis have been characterized and found to be relatively non-varying among different strains. Circumstantial evidence exists in support of the hypothesis that the B. catarrhalis beta-lactamase is a virulence determinant.

Moraxella Catarrhalis is very common in infants and young children, mostly causing otitis media (ear infections). Over 15 to 20% of all cases of otitis media are caused by Moraxella. It is also found in around 2 to 4 million people that suffer from chronic obstructive pulmonary disease. Lipooligosaccharide (LOS), a major outer membrane component of Moraxella catarrhalis , is a possible virulence factor in the pathogenesis of human infections caused by the organism. However, information about the roles of the oligosaccharide chain from LOS in bacterial infection remains limited.

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.

Box 85,500, NL‐3508 GA Utrecht, The Netherlands One of the most important factors is upper respiratory tract viral infection. During infection, pathogens migrate into the middle ear along the eustachian tube and cause inflammation, leading to congestion of the eustachian tube, which in turn causes a negative pressure in the middle ear.

The genus Moraxella is a member of the family Moraxellaceae.Moraxella catarrhalis and Branhamella catarrhalis are homotypic synonyms and it has been suggested that the genus should be divided into two subgenera, Moraxella and Branhamella.The moraxellae are short, plump, Gram-negative rods (1.0–1.5 × 1.5–2.5 µm) that characteristically occur in pairs (particularly those 2009-09-01 Recently, we showed that complement resistance is an important virulence factor of Moraxella (Branhamella) catarrhalis.
