Traumatic wound infection due to Bacillus cereus in an immunocompromised patient: a case report.

A young man recently responding to immunosuppressive therapy for acute myelocytic leukemia was admitted with fever and haemorrhagic blebs on both extremities after sustaining some scratch marks in a muddy pond. Gram stains of the hemorrhagic fluid in the blebs revealed many gram positive bacilli. B. cereus was identified from culture of tissue fluid. He did not respond to therapy despite bacteriological cure. Terminally, he developed Pseudomonas aeruginosa bacteremia and generalized bleeding.
