Infection and Branhamella catarrhalis.
Of the Gram-negative cocci found in the nasopharynx to which any pathogenic status can be attributed, Neisseria meningitidis and Neisseria (Branhamella) catarrhalis have gained significant notoriety. Traditionally, B. catarrhalis is regarded as a nasopharyngeal commensal and thus there is, in general, considerable reluctance to accept that B. catarrhalis may be a pathogen when it is seen. Hence, it is under-reported or totally ignored though there is more awareness regarding its pathogenic potential, particularly as an increasingly high incidence of beta lactamase producing strains is being reported from many countries. The importance of this development concerns the choice of routine antibiotic therapy as ampicillin, to which this organism was previously sensitive, may no longer be effective.
