Thus, the reaction should be watched to observe a positive catalase reaction. Catalase A total of 176 strains identified as Branhamella catarrhalis were isolated from various clinical specimens, mainly sputum (71), pharynx (49), eye (24), nose (11), ear (6) and tracheal aspirate (7). B. catarrhalis appeared as Gram-negative cocci in white colonies which were oxidase- and catalase-positive and which did not produce acidification Branhamella catarrhalis has a pinkish-brown pigmentation on Chocolate Agar. Colonies at 48 hours are approximately 2-2.5mm in diameter, hemispherical, becoming larger and flat or convex with prolonged incubation. The colonies have a "hockey puck" consistency and may be moved intact over the surface of the medium using an inoculating loop. Moraxella catarrhalis, formerly known as Branhamella catarrhalis, is a Gram-negative, aerobic, nonmotile, nonspore-forming, oxidase-positive, and catalase-positive diplococcus. In tests of 728 cultures, including 460 N. gonorrhoeae, 4 Neisseria lactamica, 257 Neisseria meningitidis, and 7 Branhamella catarrhalis, both Superoxol (30% H2O2; J. T. Baker Chemical Co., Phillipsburg, N.J.) and amylase inhibition tests were 100% sensitive (positive) for 20-h cultures of N. gonorrhoeae.

DNASE TEST"1 Butyrate disk test is a rapid identification test for the detection of Moraxella catarrhalis on the basis of their ability to utilize bromochloro-indolyl butyrate or 4-methylumbelliferyl butyrate. Moraxella (Branhamella) catarrhalis is now recognized as a major pathogen that causes otitis media, sinusitis, conjunctivitis, bronchitis, and pneumonia. 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..

It has been reported that some strains of N. gonorrhoeae may produce a false negative result with Gonochek -II when isolated on certain selective media, such as Improved Thayer-Martin. If the Presently, Branhamella catarrhalis has been delegated to the genus Moraxella and has been renamed Moraxella catarrhalis. M. catarrhalis on gram stain is a gram-negative diplococcus with a tendency to resist decolorizing (83). The size of the organism varies; it is often larger than the meningococcus or gonococcus.

However, false-positive reactions mayoccurwith mixedcultures. Moraxella(Branhamella)catarrhalis is nowrecognizedas amajorpathogenthatcausesotitis media,sinusitis, conjunc-tivitis, bronchitis, and Se hela listan på antimicrobe.org The prevalence of M. catarrhalis colonization depends on age. 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.
