However, no vaccine candidates for M. catarrhalis have progressed to clinical trials, and information regarding the distribution of M. catarrhalis virulence factors

Virulence factors are molecules produced by bacteria, viruses, fungi, and protozoa that add to their effectiveness and enable them to achieve the following. 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. One of these virulence factors is the ability of M. catarrhalis to resist the action of complement (9, 12, 17, 20, 24-26).

Branhamella catarrhalis virulence factors

During this period, microbiological and molecular diagnostic techniques have been developed and improved for M. catarrhalis, allowing the adequate determination and taxonomic positioning of this pathogen. Zusammenfassung. Moraxella catarrhalis wurde vor über 100 Jahren erstmals beschrieben. Erst im letzten Jahrzehnt wurde die Relevanz von M. catarrhalis als Erreger bei Otitis media (vorwiegend bei Kindern), bei Sinusitiden sowie der nosokomialen Pneumonie bei abwehrgeschwächten Patienten erkannt. die wesentlichen Pathogenitätsfaktoren stellen dabei Endotoxin, Histamin sowie chemotaktische 2019-01-29 · Moraxella catarrhalis is a type of bacteria that can cause infections in children as well as adults who have weakened immune systems.

catarrhalis is armed with numerous virulence factors to allow its invasion and colonization of human respiratory tract. Several of these factors have been identified and characterized in the last decade including Se hela listan på antimicrobe.org explained by the high carriage rates of Moraxella (Branhamella) catarrhalis in this age group. Nosocomial infections by this organism are also evident (Wright et al., 1990).

Generally, the pathogenicity of this bacterium, like other microorganisms, depends on the ability to escape from the host defense mechanisms and binding to cellular and mucus layer, as well ( 4 ). One of the most important factors is upper respiratory tract viral infection.

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.
