摘要

Mouse monoclonal antibodies (MAbs) were produced by using yellow grouper nervous necrosis virus (YGNNV) as an immunogen, isolated from infected yellow grouper, Epinephelus awoara (Temminck & Schlegel), and propagated in GB cells. In enzyme linked immunosorbent assay (ELISA), 43 hybridoma clones secreting MAbs strongly reacted with the purified virus. Ten of them showed a higher neutralization index (NI) value between 6.5 and 4.5 (log10 NI) than the other 33 MAbs against YGNNV infection in cell culture. All 10 MAbs belonged to the IgG isotype with a K light chain and recognized the 42 kDa coat protein of YGNNV by Western blot analysis. Immunohistochemical results demonstrated that the viral signals co-located with pathological lesions observed in retina, brain and spinal cord. These results indicate that the MAbs are useful for confirmative diagnosis of YGNNV infection.
