This chapter covers Miamiensis avidus and related species parasitizing fish and other aquacultured species. Focus is given on the tissue and geographical distribution, host range, transmission, impact on fish production, diagnosis, external and internal lesions, histopathology, physiopathology and...

This chapter describes the epidemiology, prevalence, distribution, transmission, physiopathology, clinical signs, diagnosis, prevention, control strategies, legislative aspects and economic impact of Streptococcus iniae and S. agalactiae infection in fishes.

This chapter describes the epidemiology, prevalence, distribution, phylogenetics, pathogenesis, diagnosis, prevention and control rhabdoviral haemorrhagic septicaemia in domestic and wild fishes.

This chapter covers the biology, morphology, transmission and impacts of Cryptobia salmositica infection. The diagnosis, clinical signs, histopathology, physiopathology, control and prevention (antiserum, monoclonal antibodies, disease resistance, vaccination, drug therapy, immunochemotherapy and...

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.
