Bacteremia and subcutaneous abscess caused by Proteus penneri in a neutropenic host

Abstract

Proteus penneri bacteremia and concomitant subcutaneous infection developed in a neutropenic patient with acute lymphocytic leukemia. The skin infection occurred while the patient was being treated empirically with cefoperazone and metronidazole. This case demonstrates the invasive potential of the microorganism in the proper setting.
