In 35 cases of anaerobic gram-negative rod (Bacteroidaceae) bacteremia only one of the 23 patients under 40 years of age died. The 12 patients more than 40 years of age died in septicemic shock. Female genital tract infection secondary to incomplete septic abortion accounted for 18 cases. The gastrointestinal tract, decubitus ulcers, and the urinary tract were responsible for a total of 12 cases. The clinical course in patients with Bacteroidaceae bacteremia secondary to incomplete septic abortion was characteristically milder than in patients with bacteremia from other foci. Bacteroidaceae bacteremia has many similarities with bacteremia from aerobic gram-negative rod organisms except that jaundice, liver abscess, and pylephlebitis are more common in Bacteroidaceae bacteremia.
