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. SUMMARY Weevaluated the superoxol (catalase) test as a means of differentiating gonococci Branhamella catarrhalis Throat 6 4 2 0 Total 387 354 32 1 results. Branhamella catarrhalis respiratory Infections oxidase-catalase reaction [13, 14].

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).

Typically positive results with Moraxella catarrhalis: The oxidase test; The catalase test; Tributyrin hydrolysis; Typically negative results with Moraxella catarrhalis: Acid from glucose; Acid from maltose; Acid from fructose; Acid from sucrose; γ (gamma)-glutamylaminopeptidase; Polysaccharide synthesis

B.CAT CONFIRM (Scott Laboratories, Inc., Fiskeville, R.I.), a rapid test for detection of tributyrin hydrolysis, wasevaluated for its ability to identify strains ofBranhamellacatarrhalis andto differentiate them fromNeisseria species andrelated species. Oninitial testing, B.CATCONFIRMwaspositive for 65 (96%)of 68B. catarrhalis strains within 30 minafter inoculation. A total of 74 clinical isolates of Branhamella catarrhalis were characterized with respect to their ampicillin, amoxicillin-clavulanate, cephalothin, cefaclor, erythromycin, tetracycline, chloramphenicol, and trimethoprim-sulfamethoxazole MICs and zones of inhibition.

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.

M. catarrhalis on gram stain is a gram-negative diplococcus with a tendency to resist decolorizing (83).
