Vibrio cholerae non-O1 non-O139 infection in an immunocompromised patient returning from Spain, July 2009

We describe a severe gastroenteritis with non-O1, non-O139 Vibrio cholerae in an immunocompromised patient returning from a holiday in Spain in July 2009. Predisposing factors and possible cholera enterotoxin production could explain the unusually grave symptomatology. The patient recovered after doxycyclin treatment.
