Toxoplasma gondii Infection in Cattle,Goats and Ticks in Xiangxi Autonomous Prefecture,Hunan Province
In order to investigate the prevalence of Toxoplasma gondii(T.gondii)in cattle,goats and ticks in Xiangxi Autonomous Prefecture,203 cattle and 238 goat serum samples collected from 7 counties were tested for antibodies by indirect hemagglutination(IHA),and 92 ticks collected from cattle body surfaces were tested for T.gondii by PCR.The results showed that the antibody positive rates of T.gondii were 16.3%(95%CI:11.1%-21.4%)and 18.5%(95%CI:13.5%-23.5%)in cattle and goats,respectively,and the antibodies were detected from samples of all the 7 counties,but the difference of antibody positive rates was not significant in cattle and goats in different regions(P＞0.05);the positive rates were 12.8%and 35.5%in female and male cattle,respectively,with statistically significant difference(P＜0.05),and 19.1%and 15.9%in female and male goats,respectively,without statistically significant difference(P＞0.05);no T.gondii was detected from ticks.In conclusion,T.gondii was widely distributed in cattle and goats in Xiangxi Autonomous Prefecture,Hunan Province,with unconspicuous characteristics of regional distribution,but seriously in male cattle,indicating a necessity to prevent T.gondii in cattle and goats,especially in male cattle.
