[Severe acute gastroenteritis due to Aeromonas in a patient colectomized for Crohn's disease].

We report a case of severe acute diarrhoea produced by Aeromonas sobria, a specimen with controversial human pathogenicity. A 26-year-old man with Crohn's disease previously colectomized was admitted with a cholera-like clinical presentation and renal failure. Aeromonas sp. can be isolated in both children and adults and in healthy people, A. hydrophila being most often detected. Severe infections due to other Aeromonas sp., usually A. sobria and A. caviae, have been rarely described. Most patients have underlying illnesses such as chronic liver disease or neoplasms. In our patient colectomy played a key role.
