摘要
为初步了解陕西省榆林地区山羊的弓形虫感染情况,于2023年5—8月从榆林市部分县区(定边县、靖边县、横山区和榆阳区)的28个羊场采集山羊血清样品共844份。采用间接血凝试验检测血清弓形虫抗体,并统计阳性率。结果发现,羊弓形虫抗体场的阳性率和样品阳性率分别为46.43%(13/28)和15.05%(127/844),其中不同县区的场阳性率和样品阳性率分别为33.33%~62.50%和10.67%~21.67%。雌性和雄性羊群弓形虫抗体阳性率分别为14.64%(101/690)和16.88%(26/154),差异较小;散养场羊群的弓形虫抗体阳性率明显高于规模化羊场,分别为21.07%(55/261)和12.35%(72/583)。此外,山羊的弓形虫抗体阳性率随年龄增长而提高,其中3岁以上羊群阳性率最高,为22.39%(15/67),而6月龄以下羊群的阳性率最低,为2.13%(1/47)。以上调查结果表明,榆林地区山羊的弓形虫病流行情况相对严重,养殖户(企业)需重视该病的防治。
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 antibody 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.
