| Popis: |
Serum samples from 641 workers of large poultry and meat-packing plants were studied in the passive hemagglutination test with the use of Salmonella complex and serogroup diagnostica. A specific increase in the level of anti-Salmonella antibodies in 60.7% of poultry plant workers and in 9.8% of meat-packing plant workers was established. Among the workers of the poultry plants the most pronounced immune shifts were detected in persons having contacts with sick poultry and pathological material and among the employees of the meat-packing plant, in those who ate raw sausage meat. A high level of antibodies in the professional groups under study was observed as early as in the first year of work at the plant and persisted over the whole period of this work. Under the conditions of constant contamination of the workers of poultry and meat-packing plants with small doses of salmonellae specific immunity to this infection was seemingly induced, which inhibited the development of the manifest forms of infection, but did not prevent the formation of chronic carrier state. |
