Abstract: In order to establish an indirect ELISA method for detection of equine herpesviruses type 4 (EHV4) antibody, the glycoprotein G (gG) protein with specific epitope worked as a detection antigen. After optimizing conditions, the indirect ELISA method was developed successfully,specificity and repeatability tests were determined. The result was that the EHV4 gG only reacted with antibodies against EHV4;but not with antibodies against EHV1; both the intro-batch and inter-batch variation coefficiencies were lower than 10%.Concordance of the indirect ELISA relative to commercial EHV1/4 antibody kit was above 90%.The results indicated that the indirect ELISA method could be used for the detection and epidemiological surveys of EHV4 infection.
