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.

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 ...

RNA‐Based Biopesticides: Pioneering Precision Solutions for Sustainable Aquaculture in China

Animal Research and One Health, Volume 3, Issue 2, Page 165-176, May 2025.
The Chinese dragon represents RNA biopesticides, which effectively counteract bacterial, viral, and parasitic threats, safeguarding aquatic life. This method is precise, focusing solely on harmful agents and sparing beneficial aquaculture species. Its innovative nature protects aquatic environments while reducing ecological footprint.

Potential Risks and Prevention Strategies of Common Diseases and Intestinal Opportunistic Pathogenic Bacteria in Bullfrog (Aquarana catesbeiana) Culture: A Review

Aquaculture Research, Volume 2025, Issue 1, 2025.
Bullfrogs (Aquarana catesbeiana) are an important aquaculture species worldwide. However, diseases have caused significant losses to the bullfrog industry. Given the crucial role of the intestinal microbiota (IM) in bullfrog growth, nutrition, immunity, and health, as well as the potential of probiotics and Chinese herbal medicine (CHM) to regulate ...

Ranaviruses and other members of the family Iridoviridae: Their place in the virosphere

Virology, 2017
Members of the family Iridoviridae, collectively referred to as iridovirids, are large, double-stranded DNA-containing viruses that infect invertebrates and cold-blooded (ectothermic) vertebrates. Infections in the former often lead to massive levels of virus replication resulting in iridescence of the infected animal and ultimately death.

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 ...

Dinucleotide biases in the genomes of prokaryotic and eukaryotic dsDNA viruses and their hosts

Molecular Ecology, Volume 33, Issue 6, March 2024.
Abstract The genomes of cellular organisms display CpG and TpA dinucleotide composition biases. Such biases have been poorly investigated in dsDNA viruses. Here, we show that in dsDNA virus, bacterial, and eukaryotic genomes, the representation of TpA and CpG dinucleotides is strongly dependent on genomic G + C content.

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.

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 ...

Virus evolution : the emergence of new ideas (and re-emergence of old ones)

, 2006
Reputed intractable, the question of the origin of viruses has long been neglected. In the modern literature 'Virus evolution' has come to refer to study more akin to population genetics, such as the world-wide scrutiny on new polymorphisms appearing ...
