This book chapter describes various aspects of scuticociliatosis: diagnosis, epidemiology, transmission, physiopathology, reservoir hosts, and control and prevention.

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.

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.
