An examination of the Iridovirus core genes for reconstructing Ranavirus phylogenies

FACETS, 2020
Ranaviruses are globally emerging infections of poikilothermic vertebrates and belong to the viral family Iridoviridae. The six species of ranaviruses are responsible for unknown numbers of infections and disease and mortality events around the world in ...

Viral Pathogens Threatening Cage‐Cultured Nile Tilapia in Lake Victoria: Epidemiology, Emerging Risks and Integrated Health Management Strategies

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
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.

Fish health, environmental contaminants, and disease management in Ghanaian aquaculture: A systematic review

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Fish health significantly influences aquaculture productivity, sustainability, food security, and public health. Despite Ghana's rapid aquaculture expansion, the sector remains constrained by widespread disease outbreaks and environmental threats. This systematic review synthesizes existing literature (2010–2024) to comprehensively assess fish

Ranavirus (family Iridoviridae) detection by polymerase chain reaction (PCR) in Chinese giant salamander (Andrias davidianus, Blanchard, 1871), China [PDF]

, 2016
A disease in farmed Chinese giant salamander (Andrias davidianus) was a common event, being an economically important threat for Chinese farms. Based on the clinical signs, epizootiology and pathogens belonging to the genus, Ranavirus was suspected as ...

Risk of Spread of Megalocytivirus pagrus1 (Infectious Spleen and Kidney Necrosis Virus) From Frozen Fillets

Journal of Fish Diseases, Volume 49, Issue 5, May 2026.
ABSTRACT Infectious spleen and kidney necrosis virus (ISKNV) is a significant threat to global aquatic food security by causing large‐scale mortality in the aquaculture of tilapia (Oreochromis niloticus) and mandarin fish (Siniperca chuatsi). ISKNV is a genogroup of Megalocytivirus pagrus1, along with RSIV and TRBIV, and their recent listing as WOAH ...

Widespread Detection of Amphibian Pathogens in Frog‐Biting Midges (Corethrellidae): Implications for Xenosurveillance

Biotropica, Volume 58, Issue 2, March 2026.
Amphibian populations worldwide face threats from emerging infectious diseases. We screened frog‐biting midges (Corethrella spp.) from Central and South America for Batrachochytrium dendrobatidis, Ranaviruses, and Trypanosoma spp. using qPCR. All three pathogens were detected, indicating that Corethrella may act as vectors and represent promising tools

Expression of frog virus 3 genes is impaired in mammalian cell lines

Virology Journal, 2008
Frog virus 3 (FV3) is a large DNA virus that is the prototypic member of the family Iridoviridae. To examine levels of FV3 gene expression we generated a polyclonal antibody against the FV3 protein 75L.

Temperature-dependent infection of freshwater turtle hatchlings, Emydura macquarii krefftii, inoculated with a ranavirus isolate (Bohle iridovirus, Iridoviridae)

FACETS, 2020
Fish, amphibians, and reptiles exhibit temperature-dependent ranaviral disease. We performed an experimental infection at four different environmental temperatures (16, 22, 28, and 34 °C) to investigate the effect of temperature on ranaviral infection in

Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

Invertebrate Iridoviruses: A Glance over the Last Decade

Viruses, 2018
Members of the family Iridoviridae (iridovirids) are large dsDNA viruses that infect both invertebrate and vertebrate ectotherms and whose symptoms range in severity from minor reductions in host fitness to systemic disease and large-scale mortality ...
