[Isolation of Yersinia enterocolitica from drinking water and human feces].

Twelve strains of Yersinia enterocolitica (46.15%) were isolated from 26 water samples of the Po river (1.3-1.5 1), 3 strains (16.67%) were isolated from 18 water samples of the Reno river (500 ml) and 1 strain (2%) was isolated from 50 fecal specimens of healthy adult subjects. It is suggested that further studies are needed in order to determine the occurrence of Yersinia enterocolitica in Italy.
