We investigated the virulence properties of four Vibrio parahaemolyticus strains causing acute gastroenteritis following consumption of indigenous mussels in Italy. The isolated strains were cytotoxic and adhesive but, surprisingly, lacked tdh, trh, and type three secretion system 2 (T3SS2) genes. We emphasize that nontoxigenic V. parahaemolyticus can induce acute gastroenteritis, highlighting the need for more investigation of the pathogenicity of this microorganism.

We report a severe case of travellers' diarrhoea in a patient returning from Ecuador to Italy with the concomitant presence of Aeromonas veronii biovar sobria and Vibrio parahaemolyticus in their faeces. Based on diagnostic results, epidemiological information and the clinical outcome, we conclude that the real aetiological agent was A. veronii biovar sobria, while V. parahaemolyticus was only transient in the intestine of the patient. © 2013 SGM.
