Abstract

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.
