An enzyme-linked immunosorbent assay (ELISA) based on recombinant SAG1-related sequence 2 of Toxoplasma gondii (rTgSRS2) was developed to detect toxoplasmosis in cats. The specificity and sensitivity of rTgSRS2 ELISA were confirmed using a series of serum samples from T. gondii-experimentally infected mice. A total of 76 field samples from cats were examined by the developed ELISA. The rTgSRS2 ELISA showed a good diagnostic performance characterized by high concordance (88.16) and kappa value (0.76) with latex agglutination test (LAT). The sensitivity and specificity of the test were 92.68% and 82.86%, respectively. These results suggest that the ELISA based on rTgSRS2 could be a useful tool for serodiagnosis of T. gondii infection in cats.
开发了一种基于重组弓形虫SAG1相关序列2（rTgSRS2）的酶联免疫吸附测定（ELISA）来检测猫的弓形虫病。使用一系列来自弓形虫实验感染小鼠的血清样本，证实了rTgSRS2 ELISA的特异性和敏感性。通过所开发的ELISA对总共76份猫的野外样本进行了检测。rTgSRS2 ELISA显示出良好的诊断性能，与乳胶凝集试验（LAT）的一致性较高（88.16），kappa值为0.76。该检测的敏感性和特异性分别为92.68%和82.86%。这些结果表明，基于rTgSRS2的ELISA可能是猫弓形虫感染血清学诊断的有用工具。
