[Systemic Salmonella Arizona infection: description of a rare surgical case].

Salmonella arizona enteritis has been described in patients resident in the southern states of the USA and in Mexico, whereas in Europe it is rarer. The virulence of this bacillus is, however, still little known and we have few descriptions of severe systemic infections, which are all present in patients with immune system impairment. Only two cases have been reported in Italy where the infection has occurred as severe sepsis with the pathogenic agent being isolated in the blood. Here we report what is, on the basis of our knowledge, the third case in Italy of a systemic Salmonella arizona infection.
