PREVALENCE OF YERSINIA ANTIBODIES IN DOMESTIC ANIMALS

摘要

Serum samples collected from 220 cows, 226 pigs, 10 sheep, 8 cats, 62 turkeys, 54 geese, 22 hens, and 7 ducks in Lublin region were tested by passive haemagglutination test with Yersinia enterocolitica (five serotypes) and Yersinia pseudotuberculosis(two serotypes) antigens. Y. enterocolitica antibodies were found in 23.2%, 17.2%), 11.3%), and 31.8% of cows, pigs, turkeys, and hens, respectively, while Y. pseudotuberculosis antibodies in 18.2%, 3.6%, 32.2%, and 13.6%), respectively. No positive response occurred in sheep, cats, geese, and ducks. The antibody response of cows to Y. enterocolitica characterised itself by high frequency of reactions to virulent serotype 0:8 (17.3%)), which was greater in comparison to that with the remaining four serotypes (5.9%)). The results suggest the importance of the consumption of undercooked beef and contaminated milk in epidemiology of yersiniosis.
