Branhamella (Neisseria) catarrhalis: criteria for laboratory identification.
Eleven clinically significant isolates of Branhamella catarrhalis grew well on modified Thayer-Martin medium and produced beta-lactamase, but did not grow on nutrient agar at 22 degrees C. Minimum inhibitory concentrations of vancomycin, colistin, and trimethoprim were found to be higher than the concentrations of these antibiotics in modified Thayer-Martin medium. The criteria necessary for la...
متن کاملEvaluation of the RIM-N, Gonochek II, and Phadebact systems for the identification of pathogenic Neisseria spp. and Branhamella catarrhalis.
Methods for identifying Neisseria spp. include conventional and modified carbohydrate degradation procedures, chromogenic enzyme substrate tests, and immunologic coagglutination tests for Neisseria gonorrhoeae. In this study, we evaluated the abilities of the RIM-N carbohydrate degradation system (American MicroScan, Campbell, Calif.), the Gonochek II enzymatic identification system (Du Pont Co...
متن کاملOtitis media caused by beta-lactamase-producing Branhamella (Neisseria) catarrhalis.
A beta-lactamase-producing Branhamella catarrhalis was isolated in pure culture from the right middle ear aspiration of an otitis media in a 3-month-old girl. The patient responded well to cefamandole treatment.
متن کاملCharacterisation of Branhamella catarrhalis and differentiation from Neisseria species in a diagnostic laboratory.
To distinguish Branhamella catarrhalis from Neisseria species a study of 140 strains was made on simple laboratory media, with particular reference to deoxyribonuclease (DNase) production, superoxol reaction, and growth characteristics. All 97 clinical isolates of B catarrhalis (58 of which were beta-lactamase positive) and eight strains of B catarrhalis from the National Collection of Type Cul...
متن کاملBranhamella catarrhalis
A modified oxidation-fermentation medium was developed as a practical medium for highly sensitive and specific detection of acid production from carbohydrates by Neisseria spp. and Branhamella catarrhalis. A total of 756 strains representing 17 Neisseria spp. and Branhamella catarrhalis were tested in this medium, in which the protein concentration was reduced relative to the carbohydrate conce...
