Seroprevalence of Toxoplasma Gondii in Cattle, Sheep and Goats in Partial Area of China
摘要
Abstract
The objectives of this study were to determine the seroprevalence of Toxoplasma gondii in cattle,sheep and goat.151 serum samples from cattle,50 milk samples from cows,490 serum samples from sheep and goats were collected from Henan, Shandong,Shanxi,Neimenggu,Yunnan,Guizhou provinces. These samples’anti-T.gondii antibodies were examined using a com-mercial indirect hemagglutination assay kits. The result showed that specific IgG against T. Gondii of 151 samples from cattle were all negative;while in 490 samples from sheep and goats,the overall seroprevalence rate was 5.71%, the female and the male had different seroprevalences surprisingly(4.03%and 9.79%respectively);the goats,sheep,mixed-breed had comparable seropreva-lences(6.58%,4.81%and 5.13%,respectively),the male goats had the highest seroprevalence of T. gondii(13.2%)and the fe-male sheep had the lowest one(2.96%).In 28 positive samples,75%serum antibody titer was 1:64 and the 25%was 1:256. Sero-prevalence of T. gondii infection increased significantly with the age of the assessed sheep or goats after 1-year-old.关键词
