The colonies were confirmed using Gram staining and biochemical tests for catalase, oxidase, DNAse, and butyrate esterase production (Remel™ catarrhalis test disc). This tributyrin spot test helped in differentiating M. catarrhalis from other nonpathogenic Neisseria species that are generally found in the respiratory tract.

An isolate was almost certainly not a gonococcus if it gave a negative superoxol test result, as all but one of 596 available gonococci gave positive test results. Branhamella catarrhalis, previously named Neisseria catarrhalis was known as a saprophytic inhabitant of the human respiratory tract. The importance as a facultative pathogen has increased during the last years. This study demonstrates the presence of B. catarrhalis in sputa and bronchial secretions … SUMMARY Moraxella catarrhalis (formerly known as Branhamella catarrhalis) has emerged as a significant bacterial pathogen of humans over the past two decades. 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. prising morphology, oxidase and catalase reactions, and rapid carbohydrate utilisation tests (RCUT).4 All the test strains and NCTCstrains were exam-inedfor DNaseandsuperoxolactivity. Agonococcus coagglutination test (Phadebact) was performed to determine possible cross reactivity with the gono-coccal antigen.

2021-03-22 · Moraxella catarrhalis is a gram-negative, aerobic, oxidase-positive diplococcus that was first described in 1896. The organism has also been known as Micrococcus catarrhalis, Neisseria catarrhalis, and Branhamella catarrhalis; currently, it is considered to belong to the subgenus Branhamella of the genus Moraxella.

M. catarrhalis was the commonest isolate and was considered to be a significant pathogen.

Typically positive results with Moraxella catarrhalis: The oxidase test; The catalase test; Tributyrin hydrolysis; Typically negative results with Moraxella catarrhalis

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.
