New!!: Moraxella catarrhalis and Virulence factor · See more » Virulence-related outer membrane protein family Introduction. Moraxella catarrhalis is a Gram-negative, human-restricted opportunistic bacterial pathogen that colonizes the upper and lower respiratory tracts.M. 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). Virulence Factors: physiology, Respiratory Tract Infections: microbiology, Moraxellaceae Infections: microbiology, Moraxella (Branhamella) catarrhalis: pathogenicity, Moraxella (Branhamella) catarrhalis: immunology, Bacterial Proteins: physiology, Biomedical Research: trends in Current Opinion in Infectious Diseases volume 22 issue 3 pages 279 This, together with the discovery of M. catarrhalis as a pathogen in its own right, has aroused scientific interest in other possible virulence factors.

Originally described in Germanas Mikrokokkus catarrha-lis byR. Pfeiffer (cited by Frosch and Kolle [125]) and then in English as Micrococcus catarrhalis (e.g., see reference 108), the species was subsequently classified in the genus Se hela listan på microbewiki.kenyon.edu K T Nguyen, E J Hansen, M A Farinha, Construction of a genomic map of Moraxella (Branhamella) catarrhalis ATCC 25238 and physical mapping of virulence-associated genes , Canadian Journal of Microbiology, 10.1139/w99-005, 45, 4, (299-303), (1999). Complement resistance is a virulence factor of Branhamella (Moraxella) catarrhalis Cees Hol Eijkman‐Winkler Institute for Medical and Clinical Microbiology, University Hospital, Room G04.614, P.O. 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. Publisher Summary For a long time, Moraxella catarrhalis (M. catarrhalis) has been considered a harmless commensal of the upper respiratory tract.

For reference, the major virulence factors currently known to be associated with M. catarrhalis pathogenesis are summarized in Table 1. M. catarrhalis can be treated with antibiotics, but it is commonly resistant to penicillin, ampicillin, and amoxicillin.

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. Virulence factor. Virulence factors are molecules produced by bacteria, viruses, fungi, and protozoa that add to their effectiveness and enable them to achieve the following.

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 Introduction.
