ABSTRACT The rapid expansion of cage culture for Nile tilapia (Oreochromis niloticus) in Lake Victoria is central to food security and profitable development in East Africa. Nevertheless, viral conditions affect the sustainability of this sector, with significant imbalances in livelihood, trade and aquaculture adaptability.

Application of Environmental DNA for Monitoring Red Sea Bream Iridovirus at a Fish Farm
Red sea bream iridoviral disease (RSIVD) causes high economic damage in mariculture in Asian countries. However, there is little information on the source of infection and viral dynamics in fish farms. In the present study, the dynamics of RSIV in a fish

ABSTRACT The aquaculture industry faces significant challenges from viral diseases, many of which are listed by the World Organisation for Animal Health (WOAH) as priority pathogens due to their impact on global finfish health and production. This review synthesizes current knowledge on the histopathology of key WOAH‐listed viral pathogens, including ...

Characterization and Antibody Preparation of the Gene Products of Grouper Iridovirus ORF5L
ABSTRACT Grouper iridovirus (GIV) is a large DNA virus belonging to the family Iridoviridae and genus Ranavirus. It consists of 139,793 base pairs (bp) and 120 open reading frames (ORFs). GIV is a key pathogen of farmed fish worldwide. The functional roles of viral genes must be determined for the early diagnosis, treatment and prevention of viral ...

Quantitative analysis of the clinical signs in marine fish induced by Megalocytivirus infection
In quantitative studies of clinical signs, rock bream of adults and juveniles infected with Megalocytivirus IVS-1 isolated from rock bream (Oplegnathus fasciatus) in Korea showed average and of spleen index respectively. In challenge experiments, Megalocytivirus IVS-1 induced 100% cumulative mortality in both adult and juvenile rock bream.

Poly(I:C) induces antiviral immune responses in Japanese flounder (Paralichthys olivaceus) that require TLR3 and MDA5 and is negatively regulated by Myd88. [PDF]
Polyinosinic:polycytidylic acid (poly(I:C)) is a ligand of toll-like receptor (TLR) 3 that has been used as an immunostimulant in humans and mice against viral diseases based on its ability to enhance innate and adapt immunity. Antiviral effect of poly(I:

Abstract Infectious diseases impact numerous organisms. Knowledge of host‐pathogen interactions and host responses to infection is crucial for conservation and management. Obtaining this knowledge quickly is made increasingly possible by a variety of genomic approaches, yet, for many species the bottleneck to understanding this, remains access to ...

Immunofluorescent analysis of P247 and P523 expression in megalocytivirus-infected fish.
Peripheral blood leukocytes were collected from turbot infected with (A, B, G, and H) or without (D, E, J, and K) megalocytivirus. The cells were treated with rat antibodies against recombinant P247 (A, B, D, and E) or P523 (G, H, J, and K) and then with
