| Abstract: | 【Objective and Method】The optimal exprssion of GST-MSA-2C fusion protein and reaction conditions of GST-MSA-2c indirect ELISA assay were studied in the previous paper.The purposes of this paper were to further discuss the specificity of GST-MSA-2C fusion protein and GST-MSA-2c indirect ELISA assay and to establish the standard procedure for this method.【Result】The positive interference of murine GST antiserum and nested PCR could be eliminated and no cross reactions were found among the piroplasms.The coincidence precentage of identified positive serum samples for bovine piroplasmosis in indirect MSA-2c ELISA were 96%..【Conclusion】The established GST-MSA-2c indirect ELISA obtained highly sensitive,specific and reproducible characteristics.which characteristics was the first case to establish an indirect MSA-2c ELISA assay method for detection of specific antibody against Babesia bovis in China.This test provided a new effective technical method for the large-scale epidemiological survey and serological dignosis of bovine babesiosis infected with Babesia bovis. |
