Аннотация
Outbreaks of koi herpesvirus (KHV) infection in carp are still a serious problem worldwide. KHV is closely related to other two cyprinid herpesviruses, pox herpesvirus (CHV) and haematopoietic necrosis herpesvirus (CyHV-2) in goldfish. In this study, two major KHV antigenic proteins (ORF62 and ORF68) were identified by immunoscreening using a KHV-specific polyclonal antibody, and then monoclonal antibodies were generated for immunodiagnostic studies. After screening hybridoma cells, one mAb against ORF68 (mAb-7C6) was obtained but no mAbs against ORF62. mAb-7C6 specifically reacted with a lysate of KHV-infected koi fin cells (KF-1 cells) but not with lysates of CHV- or CyHV-2-infected KF-1 cells in an immuno-blotting analysis. Similar results were shown in the following tests: (1) a indirect fluorescent antibody test using infected KF-1 cells and (2) an immunohistochemical investigation by fast red stain (infected liver) or FITC detection (infected spleen). These results suggested that mAb-7C6 specifically reacts with KHV ORF68 protein.
