RT Journal Article T1 Fish Iridoviridae: infection, vaccination and immune response A1 Leiva Rebollo, Rocío A1 Labella Vera, Alejandro Manuel A1 Gémez Mata, Juan A1 Castro-López, María Dolores A1 Borrego García, Juan José K1 Iridovirus AB Each year, due to climate change, an increasing number of new pathogens are being discovered and studied, leadingto an increase in the number of known diseases affecting various fish species in different regions of the world. Virusesfrom the family Iridoviridae, which consist of the genera Megalocytivirus, Lymphocystivirus, and Ranavirus, cause epizooticoutbreaks in farmed and wild, marine, and freshwater fish species (including ornamental fish). Diseases causedby fish viruses of the family Iridoviridae have a significant economic impact, especially in the aquaculture sector.Consequently, vaccines have been developed in recent decades, and their administration methods have improved.To date, various types of vaccines are available to control and prevent Iridoviridae infections in fish populations.Notably, two vaccines, specifically targeting Red Sea bream iridoviral disease and iridoviruses (formalin-killed vaccineand AQUAVAC® IridoV, respectively), are commercially available. In addition to exploring these themes, this reviewexamines the immune responses in fish following viral infections or vaccination procedures. In general, the evasionmechanisms observed in iridovirus infections are characterised by a systemic absence of inflammatory responsesand a reduction in the expression of genes associated with the adaptive immune response. Finally, this reviewalso explores prophylactic procedure trends in fish vaccination strategies, focusing on future advances in the field.
