Moraxella Ovis
''Moraxella'' is a genus of gram-negative bacteria in the family Moraxellaceae. It is named after the Swiss ophthalmology, ophthalmologist Victor Morax. The organisms are short Rod-shaped bacteria, rods, coccobacilli, or as in the case of ''Moraxella catarrhalis'', diplococci in morphology, with asaccharolytic, oxidase-positive, and catalase-positive properties.Ala'Aldeen, D. A. A. (2007). "Neisseria and moraxella". In Greenwood, David; Slack, Richard; Peitherer, John; & Barer, Mike (Eds.), ''Medical Microbiology'' (17th ed.), p. 258. Elsevier. . ''M. catarrhalis'' is the clinically most important species under this genus. Roles in disease The organisms are commensals of mucosal surfaces and sometimes give rise to opportunistic infection. * ''Moraxella catarrhalis, M. catarrhalis'' usually resides in respiratory tract, but can gain access to the lower respiratory tract in patients with chronic chest disease or compromised host defenses, thus causing tracheobronchitis and pneumoni ...

Moraxella Atlantae
''Moraxella atlantae'' is a Gram-negative, oxidase-positive and catalase-positive, rod-shaped, nonmotile bacterium in the genus ''Moraxella''. First described in 1976 it was recognized as a rare opportunistic pathogen in humans starting in 1991. Taxonomy and microbiological characteristics ''Moraxella atlantae'' was first described as a new species in 1976 based on biochemical and microbiological culture , microbiological growth characteristics:Bøvre, K., et al. "Moraxella atlantae sp. nov. and its distinction from Moraxella phenylpyrouvica." International Journal of Systematic and Evolutionary Microbiology 26.4 (1976): 511-521. It resembled ''Moraxella phenylpyruvica'', but differed in "simultaneous lack of urease and phenylalanine and tryptophan deaminase activities, inability to grow on solid medium at 4 to 10°C, relative salt sensitivity, and different behaviour on bile-containing media." In difference it also contains n-octadecanol and mannose. It is a non-fermenter and ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
