Comparison of the Immunogenicity of Three Grass Carp Hemorrhage Viruses
Abstract: The immunogenic comparison of three grass carp hemorrhage viruses, GCHV873, GCHV875 and GCHV876 derived from different areas has been carried out on the basis of the levels of the elicited serum antibodies in rabbits. The anti-GCHV873 antibody titre was 2 folds higher than GCHV875 and 8 folds than GCHV876. Their neutralizing titres were 1 : 1778(10~(-3.25)), 1: 386(10~(-2.59)) and 1: 181(10~(-2.25)) respectively.These experimental results suggested that GCHV873 is a stronger immunogen among three isolates.
