Abstract: 

Escherichia hermannii was isolated from the blood, stool and wound culture of a 40 year old male patient who was treated with chemotherapy for a retroperitoneal sarcoma. The biotyping and antibiogram pattern confirmed that all the organisms from the three sites were an identical strain. The same organism was also isolated from repeated blood cultures of this patients and this suggested that Escherichia hermannii could be a significant pathogenic organism in an immunocompromised patient.
