چکیده
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.

Moraxella catarrhalis, a human respiratory tract pathogen.
Moraxella catarrhalis is an exclusively human pathogen and is a common cause of otitis media in infants and children, causing 15%-20% of acute otitis media episodes. M. catarrhalis causes an estimated 2-4 million exacerbations of chronic obstructive pulmonary disease in adults annually in the United States. M. catarrhalis resembles commensal Neisseria species in culture and, thus, may be overlo...
متن کاملBranhamella catarrhalis: an organism gaining respect as a pathogen.
Branhamella catarrhalis was formerly regarded as a common, essentially harmless inhabitant of the pharynx. This misapprehension was caused, in part, by confusion with another pharyngeal resident, Neisseria cinerea. The two organisms can now be differentiated by the positive reactions of B. catarrhalis in tests for nitrate reduction and hydrolysis of tributyrin and DNase. B. catarrhalis is curre...
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 (Neisseria) catarrhalis--a lower respiratory tract pathogen?
Branhamella (Neisseria) catarrhalis was identified as a probable respiratory tract pathogen in seven patients, four with pneumonia and three with bronchitis. Five of the B. catarrhalis isolates produced beta-lactamase. Production of beta-lactamase correlated with penicillin resistance by the standardized disk diffusion method and also with high minimal inhibitory concentrations of penicillin fo...
متن کاملAntibiotic susceptibility of beta-lactamase-producing strains of Branhamella (Neisseria) catarrhalis.
All 11 clinically significant isolates of Branhamella catarrhalis examined in this study were found to produce beta-lactamase. The enzyme was apparently not plasmid associated since extrachromosomal deoxyribonucleic acid was not detected in any of the strains. The beta-lactamase activity of all strains was significantly depressed by the beta-lactamase inhibitors clavulanic acid and CP 45899. Ba...
