The Role of Gut Microbiota in Fish Viral Infection: Mechanisms and Microbiota‐Targeted Interventions

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Viral diseases represent one of the major threats to the global aquaculture industry. In recent years, the relationship between gut microbiota and viral infections in fish has garnered increasing attention. The gut microbiota contributes critically to fish health and is involved in antiviral defense through immune regulation, secretion of microbial ...

Comparative Genomics of an Emerging Amphibian Virus

G3: Genes, Genomes, Genetics, 2016
Ranaviruses, a genus of the Iridoviridae, are large double-stranded DNA viruses that infect cold-blooded vertebrates worldwide. Ranaviruses have caused severe epizootics in commercial frog and fish populations, and are currently classified as notifiable ...

Genomic sequence of a ranavirus (family Iridoviridae) associated with salamander mortalities in North America

Virology, 2003
Disease is among the suspected causes of amphibian population declines, and an iridovirus and a chytrid fungus are the primary pathogens associated with amphibian mortalities. Ambystoma tigrinum virus (ATV) and a closely related strain, Regina ranavirus (RRV), are implicated in salamander die-offs in Arizona and Canada, respectively.

Unveiling Origin Pitfalls in Metagenomic Surveillance for Emerging Infectious Diseases: Parvoviruses as a Model

iMetaMed, Volume 1, Issue 1, September 2025.
A diverse reagent‐associated virome, including parvoviruses, misleads zoonotic surveillance. By leveraging large language models (ChatGPT‐4o), we construct a virus discovery data framework (PVDDC) and ParvoDB to access and correct host misattributions, thereby enhancing the accuracy of metagenomic surveillance for emerging zoonotic diseases.

Systemic iridovirus from threespine stickleback Gasterosteus aculeatus represents a new megalocytivirus species (family Iridoviridae) [PDF]

Diseases of Aquatic Organisms, 2012
Megalocytiviruses have been associated with epizootics resulting in significant economic losses in public aquaria and food-fish and ornamental fish industries, as well as threatening wild fish stocks. The present report describes characteristics of the first megalocytivirus from a wild temperate North American fish, the threespine stickleback ...

Megalocytivirus: A Review of Epidemiology, Pathogenicity, Immune Evasion, and Prevention Strategies

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Megalocytivirus, 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.

Transcriptome analysis of Frog virus 3, the type species of the genus Ranavirus, family Iridoviridae

Virology, 2009
Frog virus 3 is the best characterized species within the genus Ranavirus, family Iridoviridae. FV3's large ( approximately 105 kbp) dsDNA genome encodes 98 putative open reading frames (ORFs) that are expressed in a coordinated fashion leading to the sequential appearance of immediate early (IE), delayed early (DE) and late (L) viral transcripts. As a

Target organs for lymphocystis disease virus replication in gilthead seabream (Sparus aurata)

Veterinary Research, 2017
The lymphocystis disease (LCD), the main viral pathology described in cultured gilthead seabream (Sparus aurata), is a self-limiting condition characterized by the appearance of hypertrophied fibroblasts (named lymphocysts) in the connective tissue of ...

Laboratory investigation into the role of largemouth bass virus (Ranavirus, Iridoviridae) in smallmouth bass mortality events in Pennsylvania rivers

BMC Veterinary Research, 2018
Background Mortality episodes have affected young-of-year smallmouth bass (Micropterus dolomieu) in several river systems in Pennsylvania since 2005. A series of laboratory experiments were performed to determine the potential role of largemouth bass ...
