[Seroepidemiological survey of chickens infected with Toxoplasma gondii in Wuxi City].

OBJECTIVE
To understand the status of scattered chickens infected with Toxoplasma gondii in Wuxi City.


METHODS
We investigated the positive rate of Toxoplasma antigen and antibody of 309 cases of scattered chickens in Wuxi, and it was compared with the positive rate of Toxoplasma antigen and antibody of 150 cases of intensive farming chickens.


RESULTS
In the 309 cases of scattered chickens, there were 29 cases of antigen positive, and the positive rate was 9.39%; there were 53 cases of antibody positive, and the positive rate was 17.15%; there were 13 cases of antigen and antibody double positive, and the double-positive rate was 4.21%.; In the scattered chickens, the overall positive rate was 22.33%, and in the intensive farming chickens, the overall positive rate was 2.67%, and there was a significant difference between them (chi2 = 29.19, P <0.01).


CONCLUSION
There is a high T. gondii infection in scattered chickens in Wuxi, so the medical, veterinary and food hygiene workers should pay more attention to it.
