Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies
ABSTRACTMegalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm.

Molecular epidemiology of Megalocytivirus in freshwater angelfish (Pterophyllum scalare) from Johor, Malaysia. [PDF]
Background and Aim: Malaysia has more than 630 culturists who are involved in the ornamental fish industry and culture 250 species, including local and exotic species. Among these viruses, megalocytiviruses have been associated with severe systemic diseases and economic losses in ornamental fish.

Genotypic Characterization of <i>Infectious Spleen and Kidney Necrosis Virus</i> (ISKNV) in Southeast Asian Aquaculture. [PDF]
Infectious spleen and kidney necrosis virus (ISKNV) is a species within the genus Megalocytivirus (family Iridoviridae), which causes high mortality disease in many freshwater and marine fish species. ISKNV was first reported in Asia and is an emerging threat to aquaculture with increasing global distribution, in part due to its presence in ornamental ...

Megalocytivirus infection in orbiculate batfish Platax orbicularis [PDF]
Megalocytiviruses cause systemic disease in both marine and freshwater fishes, negatively impacting ornamental and food fish aquaculture. In this report, we characterize a megalocytivirus infection in a captive marine ornamental fish, the orbiculate batfish Platax orbicularis.

Megalocytivirus infection in cultured Nile tilapia Oreochromis niloticus [PDF]
Megalocytiviruses, such as infectious spleen and kidney necrosis virus (ISKNV), induce lethal systemic diseases in both ornamental and food fish species. In this study, we investigated an epizootic affecting Nile tilapia Oreochromis niloticus cultured in the US Midwest.

Characterization of a Novel Megalocytivirus Isolated from European Chub (Squalius cephalus) [PDF]
A novel virus from moribund European chub (Squalius cephalus) was isolated on epithelioma papulosum cyprini (EPC) cells. Transmission electron microscopic examination revealed abundant non-enveloped, hexagonal virus particles in the cytoplasm of infected EPC cells consistent with an iridovirus.

Improving tilapia biosecurity through a value chain approach
Abstract Tilapia aquaculture is a major source of animal protein, with global production reaching over 6 million tonnes in 2020. The rapid growth of the tilapia sector has led to a number of emerging disease threats and subsequent production losses. Risk analysis can provide a targeted approach for improving biosecurity in the tilapia sector.

Ranaviral infections are becoming frequent, severe, and widespread, causing mortality in native biodiversity and cultured species in Asia. Ranaviruses have a broad host range and are transmitted through live animal trade. Ranaviral disease is predominantly a summer disease, which may spread unhindered with global warming. The controlling of the disease
