Chronic Diarrhea Due to in an Immunosuppressed Patient with a Pancreas-Kidney Transplant.

The genus belongs to the family. A patient with a pancreas-kidney transplant had multiple episodes of abdominal sepsis after surgery. was isolated in the ascitic and biliary fluid drains. After discharge, the patient had several diarrhea episodes, and was isolated in four stool samples. We decided to test whether the one strain that we initially isolated in ascitic fluid was the same that appeared in the successive stool samples. Five isolates of were found in the patient. Identification was performed using the MALDI-TOF system and confirmed via multiplex PCR. The analysis of the REP-PCR fingerprint patterns showed one cluster and confirmed that all isolates were related. We also demonstrated the virulent character of this species associated with genes encoding different toxins (act, alt, ast, hlyA, and aerA). The virulence of this species is associated with the expression of genes that encode different toxins, structural proteins, and metal-associated proteins. This case report highlights the severity of this disease, especially in immunocompromised patients, and its adequate treatment.
