Abstract:
Propionibacterium (Propionimicrobium) lymphophilum is a Gram-positive anaerobic rod involved in few human diseases. We report a rare case of bacteremia due to this microorganism in an elderly patient. A 95-year-old woman without a remarkable medical history presented with dyspnea, chest pain and fever for seven days. Blood cultures resulted in isolation of P. lymphophilum. Resistance only to metronidazole was found. Treatment with amoxicillin-clavulanic acid was established, and the patient was discharged and improvement of her general condition was documented.
