A nosogeographic study in the Ukrainian SSR revealed 3 zones of gastroenterocolitis morbidity: low, average and above average. Also cartographically were determined 3 Escherichia infection morbidity zones in children under 1 year of age. Conformity of pathogenic Escherichia serogroups (025, 026, 055, 0119 and others) among most humans, animals and environment suggest circulation of pathogens by the cycle: man (patient, carrier)--environment--animals (birds) and vice versa.
