Septicemia in Neutropenic Patients Infected with Clostridium tertium Resistant to Cefepime and Other Expanded-Spectrum Cephalosporins

Clostridium tertium was isolated from two immunocompromised patients with septicemia, fever, and gastrointestinal symptoms. The strains were resistant to ceftazidime, cefepime, and clindamycin; intermediately resistant to penicillin; and susceptible to metronidazole, quinolones, and vancomycin.
