[Septicemia caused by Branhamella (Neisseria) catarrhalis in an immunosuppressed patient].

A case is reported of Branhamella catarrhalis septicemia occurring during the aplastic phase of treatment for acute myeloblastic leukemia. Skin lesions were observed which are ordinarily seen in chronic gonococcal or meningococcal septicemia. The pathogenic role of this agent, which is normally considered nonaggressive, is discussed.
