Purpose: We report three cases of enterocolitis associated with pathogenic Escherichia coli infection in renal transplant recipients.
Methods/results: Patients presented with abdominal pain and diarrhea at 1, 3 and 7 years after living-related renal transplantation. Pathogens of enterocolitis were identified by stool culture as verotoxin-2-producing O157:H7 E. coli, non-verotoxin-producing E. coli 06 and 0125. All patients were basically treated with fluid replacement with additional fosfomycin administration in the patient with O157:H7 E. coli infection. Immunosuppressive drugs were kept at maintenance doses throughout the treatment.
Conclusion: All patients recovered uneventfully within 10 days after the onset of enterocolitis without severe complications.
