Abstract:In order to strengthen the protection of livestock and poultry resources and promote the rapid development of Chakouyi horse industry,and provide technical guidance for the prevention and control of horse disease.As one of the important contents of the general survey of equine protozoonosis,the detection of equine toxoplasmosis was carried out in the whole county.Blood samples were collected from horse veins,and the serum was centrifuged.Indirect hemagglutination test(IHAT) was used to detect the Toxoplasma gondii infection antibody in horse serum qualitatively and quantitatively.240 horse blood samples were sampled from 12 towns.The results showed that 9 samples were positive for antibodies,with a positive rate of 3.75%.Among these,20 samples were collected from Qilian town,5 of which were positive,resulting in a positivity rate of 25.0%.In the 240 samples tested,the serum antibody titers of 0,1∶4,1∶16 and 1∶64 were 88,78,65 and 9 samples respectively.The test results show that toxoplasmosis in horse in Tianzhu county has been epidemic among equine animals within the controllable and safe range over many years,which has not had a serious impact on the development of horse industry in Tianzhu county.However,this testing work remains an important supplement to the prevention and control of zoonotic infectious diseases in Tianzhu county.
