榆林地区山羊弓形虫血清学调查与分析OA北大核心

In order to understand the infection of toxoplasma gondii for goat in Yulin,Shaanxi province,844 serum samples were collected from 28 goat farms in Dingbian county,Jingbian county,Hengshan district and Yuyang district of Yulin city from May to August 2023.Plasma antibodies to Toxoplasma gondii were detected by indirect hemagglutination test and the positive rates were calculated.The results showed that the positive rates of the farm and sample were 46.43%(13/28)and 15.05%(127/844),respectively.The positive rates of the farm and sample in different counties(districts)were 33.33%-62.50%and 10.67%-21.67%,respectively.There was little difference in the positive rate of toxoplasma antibodies between female and male sheep,as 14.64%(101/690)and 16.88%(26/154),respectively.The positive rate of toxoplasmosis anti-body was significantly higher in free-range sheep farms than in large-scale sheep farms,as 21.07%(55/261)and 12.35%(72/583),respectively.In addition,the positive rate of toxoplasmosis antibody in goats increased with the increase of age,and the positive rate in goats over 3 years old was the highest(22.39%)(15/67),while the positive rate in goats under 6 months old was the lowest(2.13%)(1/47).The results indicated that the prevalence of goat toxoplasmosis in Yulin area was relatively serious,and farmers(enterprises)should pay attention to the prevention and control of goat toxoplasmosis.
