MORAXELLA CATARRHALIS OUTER MEMBRANE

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. M. catarrhalis is a human pathogen with an affinity for the human upper respiratory tract. Other primates, such as macaques, might become infected by this bacterium.

It is also known as Branhamella catarrhalis, It is considered to be a subgenus Branhamella of the genus Moraxella . Moraxella catarrhalis is an exclusively human commensal and mucosal pathogen. For most of the past century, Moraxella catarrhalis was regarded as an upper respiratory tract commensal organism. However, since the late 1970s it has been clear that M. catarrhalis is an important and common human respiratory tract pathogen.

Övriga Moraxella-arter Moraxella catarrhalis (M. catarrhalis) is a type of bacteria that’s also known as Neisseria catarrhalis and Branhamella catarrhalis.

The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of … 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. complement resistance. Lipooligosaccharide is considered one possible virulence factor.

Superinfection with mycobacterial organisms such as M. avium complex almost always requires multiple drug regimens that include clarithromycin or azithromycin ; rifampin or rifabutin ; and ethambutol . M. catarrhalis was recovered significantly more often from sputum samples of good quality (5%) than from poor quality samples (0.5%), and when present, it was found mostly in the presence of high Of these species the most clinically important are Moraxella catarrhalis, M. lacunata, M. nonliquefaciens, M. osloensis, M. atlantae, and M. phenylpyruvica.. Some strains are unique to animals such asM. bovis, M. canis, M. caprae.In the past these strains were very susceptible to penicillin, however currently there have been cases of Moraxella species producing beta-lactamases. M. catarrhalis has been shown to synthesize at least three proteins (i.e., UspA1, UspA2, and Hag) that have been classified as trimeric autotransporters and one additional protein that is considered a conventional autotransporter (i.e., McaP) (for reviews, see references 11, 19, and 35).
