In this study, we investigated whether mouse polyclonal anti-serum raised against the YHV gp116 or gp64 structural glycoproteins could neutralize YHV infectivity as determined using an in vitro quantal assay in primary cultures of lymphoid organ cells. Anti-gp116 antiserum showed virus-neutralizing activity whereas anti-gp64 antiserum failed to inhibit infection. The results suggest that gp116 antiserum blocks binding of virions to cellular receptors to facilitate YHV entry into lymphoid organ cells.Mahidol UniversityAgricultural and Biological SciencesAntiserum to the gp116 glycoprotein of yellow head virus neutralizes infectivity in primary lymphoid organ cells of Penaeus monodonArticleSCOPUS10.3354/dao063085
