The dynamics of annual morbidity in salmonellosis caused by S. enteritidis among the population of Perm during the period of 1987-1992 was analyzed. Blood sera taken from 4,689 practically healthy donors and from 6,997 hens at poultry breeding complexes were studied in the passive hemagglutination test with the use of complex Salmonella diagnosticum. The study revealed that seasonal rises in morbidity caused by S. enteritidis in winter and spring months, as well as in autumn months, were linked with the activation of the epizootic process of Salmonella infection among hens at poultry-breeding complexes during these periods of the year. A rise in the level of anti-Salmonella antibodies in poultry and human blood sera was found to be the precursor of the aggravation of the epidemic situation.
