Moraxella catarrhalis is classified with the genera Neisseria, Moraxella, Kingella, and Acinetobacter in the family Neisseriaceae. The taxonomic position of M. catarrhalis is currently being debated; it has been proposed that M. catarrhalis be assigned to the genus Moraxella (M. catarrhalis) in the family Moraxellaceae, or to its own genus, Branhamella, in the family Branhamaceae. In the early 1900s, descriptions of “N. cat…

Catalase and oxidase tests were positive, while beta-lactamase activity was negative. The isolate was identified as M. catarrhalis by using API NH (bioMérieux, France) identification strips. M. catarrhalis was isolated from five different blood culture specimens of the patient. The focus for bacteremia could not be …

Strains of N. gonorrhoeae that are negative for prolylaminopeptidase have been reported. Gram-negative, oxidase-positive diplococci isolated on selective media that are negative Another genus with which they can be confused, especially the species M. catarrhalis, it's with Neisseria, both for its morphology and for the oxidase test.. In this case they are differentiated by the incapacity of the gender Moraxella to form acid from carbohydrates, while most of the Neisseria if they are able to ferment some carbohydrates. Only oxidase-POSITIVE, catalase-POSITIVE, and gram-NEGATIVE diplococci should be tested with Gonochek -II. (See NOTE below.) Note: Kingella species may grow on Modified Thayer-Martin and other selective media.

Catalase enzyme is a common enzyme that is found in all living beings that survive in oxygen and catalyzes the decomposition of hydrogen peroxide, releasing water and oxygen. Catalase is an essential enzyme in pathogenic organisms … M. catarrhalis produces oxidase, catalase, and DNAse, which are used for speciation. Diagnosis An etiologic diagnosis of the most common clinical manifestations of M. catarrhalis (otitis media in children and exacerbations of COPD in adults) is not made routinely in clinical practice. Moraxella Catarrhalis Biochemical tests Catalase POS, Oxidase Pos, Carbohydrate Utilization, Asaccharolytic (NEG for glucose, Maltose, Lactose, Sucrose) Moraxella Catarrhalis Biochemical POS reactions Superoxol Test (30% hydrogen Similar to the catalase test but instead of a 3% hydrogen peroxide solution a 30% is used.

Then suspected Moraxella catarrhalis colonies were biochemically tested.

Finally, antibiotic sensitivity tests were carried out and beta-lactmase production was inspected for each isolate using nitrocefin disks. After tests, 19 (4.7%) from the collected samples were positive for Moraxella catarrhalis. Of these, 15 (78.9%) isolates showed typical bands of M. catarrhalis while 4 (21.0%) isolates were negative.
