Vibrio cholerae O2 as a cause of a skin lesion in a tourist returning from Tunisia.

Isolates of Vibrio cholerae other than O1 and O139 (non O1 Vibrio cholerae) are associated with sporadic diarrheal disorders, and limited outbreaks of diarrhea, and have often been reported in association with extraintestinal infections. The majority of cases of non O1 Vibrio cholerae infection involve immunocompromised patients with hematologic malignancies or cirrhosis. In Italy, very few cases of gastrointestinal and extraintestinal infections due to non O1 Vibrio cholerae have been described in the past years. We describe a case of non O1 Vibrio cholerae infection with cutaneous bullous lesions in a tourist returning from Tunisia.
