B. catarrhalis appeared as Gram-negative cocci in white colonies which were oxidase- and catalase-positive and which did not produce acidification oxidase, and catalase tests to tributyrin hydrolysis provides a means of positive same day identification ofBcatarrhalis. Branhamella catarrhalis has long been regarded as a animal species Branhamella caviae, Branhamella ovis, and Branhamella cuniculi from the Neisseria spp. (12). The hydrolysis of tributyrin has not been extensively exploited for identification ofB. catarrhalis in the clinical laboratory.

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.
