Infectious haematopoietic necrosis virus (IHNV) is a Rhabdovirus that causes significant disease in Pacific salmon (Oncorhynchus spp.), Atlantic salmon (Salmo salar), and rainbow and steelhead trout (O. mykiss). IHNV causes necrosis of the haematopoietic tissues, and consequently it was named...

This chapter describes Epizootic haematopoietic necrosis virus (EHNV) and European catfish virus (ECV), which belong to a group of emerging pathogens - all of which are relevant to fish health - for which understanding of their epizootiology is incomplete. EHNV and ECV belong to the genus Ranavirus ...
