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. Over the same period, studies Branhamella catarrhalis causes infections ranging from acute, localized infections such as otitis media, sinusitis, and bronchopneumonia to life threatening, systemic diseases including endocarditis and meningitis.

Branhamella catarrhalis biochemical tests

Because this organism can be found at the same sites as pathogenicNeisseria spp. and shares some physiological and biochemical characteristics, it is important to have a screening test for differentiation of Studies have shown that M catarrhalis colonizes the upper respiratory tract in 28-100% of humans in the first year of life. In adults, the colonization rate is 1-10.4%. Colonization appears to be MEDIUM FOR MORAXELLA (BRANHAMELLA) CATARRHALIS 547 TABLE 1.

The organisms can be presumptively identified as Moraxella (Branhamella) catarrhalis. Jul 1, 2009 Branhamella catarrhalis was subsequently placed in the genus A variety of biochemical tests can distinguish M. catarrhalis from Neisseria. The emergence of the first antibiotic-resistant strain of M. catarrhalis was noted in The colonies were confirmed using Gram staining and biochemical tests for beta-lactamase of Moraxella (Branhamella) catarrhalis,” Antimicrobial Evaluation of a rapidmethod for- identifying Branhamella catarrhalis.

Inturn, this has led to the renaming of certain species, as well as the addition of new ones. As the tools for defining bacterial genus and species relatedness become more refined, bacterial nomenclature necessarily becomes more complex. There is provided by the present invention, a method for detecting the presence of Branhamella catarrhalis, said method comprising; depositing and fixing on an inert support a sample containing DNA fragments in substantially single stranded form, contacting said fixed single stranded genetic material with a labelled probe consisting of a fragment of B. catarrhalis chromosomal DNA, identified TABLE 1.

Antibiotic susceptibility test was done by Kirby Bauer disk May 25, 2015 Acharya Tankeshwar Biochemical tests in Microbiology, Laboratory Diagnosis of Bacterial Disease 0 Principle: The butyrate disk is a rapid test for the detection of the enzyme butyrate esterase in identifying Moraxella (Branhamella ) catarrhalis. Tanaka, H., K. Oishi, F. Sonoda, A. Iwagaki, T. Nagatake, and R. Matsumoto. 1992 Biochemical analysis of lipopolysaccharides from respiratory pathogenic Branhamella catarrhalis strains and the role of anti-LPS antibodies in Branhamella respiratory infections [in Japanese] Kansenshogaku Zasshi 66 709–715 PubMed Google Scholar Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. 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. In contrast, true cocci, such as most Neisseria spp.
