Monoclonal-Antibody-Based Immunodot Assay Distinguishes between Viral Hemorrhagic Septicemia Virus (VHSV) and Infectious Hematopoietic Necrosis Virus (IHNV)
Abstract:Abstract

An immunodot assay has been developed with two monoclonal antibodies that recognize conserved epitopes on the nucleoproteins of viral hemorrhagic septicemia virus (VHSV) and infectious hematopoietic necrosis virus (IHNV). Monoclonal antibody 1NDW14D, which recognizes a conserved epitope on the nucleoprotein of IHNV, recognized 80 of 81 IHNV isolates spotted on nitrocellulose, but none of 8 VHSV isolates. Monoclonal antibody IP5B11, which recognizes a conserved epitope on the nucleoprotein of VHSV, reacted with all eight isolates of VHSV, but with none of the IHNV isolates. Neither monoclonal antibody bound to other rhabdoviruses spotted on nitrocellulose: spring viremia of carp virus (SVCV), pike fry rhabdovirus (PFRV), a new Danish eicosid rhabdovirus unrelated to PFRV, and rhabdovirus anguilla (EVX).
