This book contains 25 illustrated chapters that describe the epidemiology, prevalence, distribution, transmission, physiopathology, clinical signs, diagnosis, prevention, control strategies, legislative aspects and economic impact of bacterial and viral diseases of fishes, including: Infectious...

The Infectious pancreatic necrosis virus (IPNV) is one of the most extensively studied and widely distributed viruses infecting marine and freshwater fishes. The geographical distribution; economic impacts of IPNV; diagnosis of the infection; pathology; pathophysiology; and the protective and...

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...

Viral haemorrhagic septicaemia virus (VHSV) is the aetiological agent of viral haemorrhagic septicaemia (VHS) and is a member of the family Rhabdoviridae within the order Mononegavirales. These viruses have single-stranded, negative-sense (nega) RNA genomes with enveloped bullet- or cone-shaped...

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 ...

The geographical distribution; economic impacts; diagnosis of the infection; pathology; pathophysiology; and the protective and control strategies against Oncorhynchus masou virus and Cyprinid herpesvirus are discussed.

The causative agent of infectious salmon anaemia is Infectious salmon anaemia virus (ISAV), the only member of the genus Isavirus, family Orthomyxoviridae. Infectious salmon anaemia is a significant infectious viral disease of farmed Atlantic salmon (Salmo salar). This article discusses the...

Channel catfish viral disease (CCVD) is an acute viraemia that occurs primarily among young (0-4 month old) channel catfish (Ictalurus punctatus) in aquaculture. The prevalence and transmission; factors that promote CCVD outbreaks; diagnosis; pathology; pathophysiology; protective and control...

This article discusses the description of Largemouth bass viral disease (LMBV); mode of transmission; geographical distribution; impacts of LMBV on fish populations; diagnosis; pathology; pathophysiology; and protective and control strategies against LMBV.

Koi herpesvirus disease (KHVD) is a herpesvirus infection that induces a lethal acute viraemia that is highly contagious in common carp (Cyprinus carpio) and varieties of C. carpio such as koi carp and ghost carp. The causative agent is classified as Cyprinid herpesvirus 3 and is transmitted...
