title: Branhamella catarrhalis septic arthritis.
abstract: An adult with spontaneous septic arthritis due to Branhamella catarrhalis is described and the literature reviewed. B. catarrhalis is an organism similar to the Neisseria species and has been implicated in a variety of systemic infections. As it is frequently resistant to penicillin, cephamycins or third generation cephalosporins may be the empiric drugs of choice for infections caused by this organism.
