Abstract
The clinical and microbiological features of 7 cases of bacteremia due to Capnocytophaga (Capnocytophaga ochracea group) are reported. They were diagnosed during 1991–93 at three hospital clinics. Five patients were 0.13 × 109/1, and all but 1 had oral lesions as a possible portal of entry. A favourable response to antibiotic therapy was recorded in all patients but one who, being profoundly granulocytopenic, rapidly succumbed to Pseudomonas aeruginosa septicemia. None of the isolates were beta-lactamase producers. In addition to penicillin the isolates were susceptible to broad-spectrum cephalosporins and ciprofloxacin, but resistant to aminoglycosides.
