摘要: [目的]调查云南省玉溪市散养牛弓形虫病流行情况并分析其可能发生的风险因素。[方法]应用酶联免疫吸附试验(ELISA)对玉溪市内9个县(市、区)采集的341份散养牛血清样本进行弓形虫抗体检测,计算该地区散养牛弓形虫抗体阳性率,分析不同地区、品种、性别、采样季节散养牛弓形虫血清抗体阳性率的统计学差异。[结果]玉溪市散养牛弓形虫感染抗体总阳性率为3.23%。不同地区(χ2=22.594,P<0.05)、品种(χ2=10.126,P<0.05)散养牛弓形虫抗体阳性率差异显著,具有统计学意义;不同性别(χ2=0.588,P>0.05)、采样季节(χ2=6.127,P>0.05)散养牛弓形虫感染抗体阳性率差异不显著,不具有统计学意义。[结论]玉溪市存在散养牛的弓形虫感染,地区和品种是散养牛弓形虫感染的主要影响因素。未来研究应进一步探讨影响不同地区和品种散养牛弓形虫抗体阳性率的具体因素,并加强对高风险地区和品种的监测和防控措施,以降低弓形虫病的传播风险,保障牛群健康和养殖效益。

Abstract: [Objective] To investigate the prevalence of toxoplasmosis infection in free-range cattle in Yuxi City, Yunnan Province, and analyze the potential risk factors associated with its occurrence. [Methods] ELISA was used to detect Toxoplasma antibodies in 341 serum samples collected from free-range cattle in 9 counties (cities and districts) within Yuxi. The positive rate of Toxoplasma antibodies in free-range cattle was calculated, and the statistical differences in antibody positivity rates based on different regions, breeds, sexes, and sampling seasons were analyzed. [Results] The overall positive rate of Toxoplasma infection antibodies in free-range cattle in Yuxi was 3.23%. Significant statistical differences in antibody positivity rates were observed between different regions (χ2=22.594, P<0.05) and breeds (χ2=10.126, P<0.05). However, no significant differences were found based on sex (χ2=0.588, P>0.05) or sampling season (χ2=6.127, P>0.05). [Conclusion] The present investigation revealed that Toxoplasma gondii infections exist in free-range cattle across multiple regions of Yuxi City, with geographical location and cattle breed identified as the primary influencing factors. Future research should further explore the specific factors influencing Toxoplasma antibody positivity rates in free-range cattle of different regions and breeds, and enhance monitoring and control measures in high-risk areas and breeds to reduce the risk of toxoplasmosis, ensuring the health of the cattle population and the economic benefits of farming.
