Potential for a live red seabream iridovirus (RSIV) vaccine in rock bream Oplegnathus fasciatus at a low rearing temperature

Vaccine, 2014
Serious economic losses have occurred in fingerlings and market-sized rock bream Oplegnathus fasciatus in Korea due to red seabream iridovirus (RSIV) infection. We demonstrated previously that viral multiplication in fish is downregulated by maintaining fish at far from optimum temperatures at the onset of disease.

Genetic vaccines protect red seabream, Pagrus major, upon challenge with red seabream iridovirus (RSIV)

Fish and Shellfish Immunology, 2006
We have investigated the protective effect of immunization of juvenile red seabream, Pagrus major, with DNA plasmids encoding the viral major capsid protein (MCP) and an open reading frame (ORF) containing a transmembrane domain against red seabream iridovirus (RSIV).

Inhibition of red seabream iridovirus (RSIV) replication by small interfering RNA (siRNA) in a cell culture system

Antiviral Research, 2008
Small interfering RNAs (siRNAs), mediators of a process of sequence-specific gene silencing called RNA interference, have been shown to have activity against a wide range of viruses and are considered to be potential antiviral tools. Here, we describe an antiviral activity of a siRNA that targets the major capsid protein (MCP) gene of red seabream ...

Establishment of rock bream Oplegnathus fasciatus embryo (RoBE-4) cells with cytolytic infection of red seabream iridovirus (RSIV)

Journal of Virological Methods, 2016
Red seabream iridovirus (RSIV) is a member of genus Megalocytivirus in the family Iridoviridae. RSIV infection causes significant economic losses of marine-fishes in East Asian countries. Grunt fin (GF) cell line has been commonly used for culturing RSIV.

Complete genome sequence and phylogenetic analysis of megalocytivirus RSIV-Ku: A natural recombination infectious spleen and kidney necrosis virus

Archives of Virology, 2017
Megalocytiviruses are classified into three genotypes, infectious spleen and kidney necrosis virus (ISKNV), red seabream virus (RSIV), and turbo reddish body iridovirus (TRBIV), based on the major capsid protein and ATPase genes. However, only a few complete genome sequences have been obtained.

Immunogenicity, retention and protective effects of the protein derivatives of formalin-inactivated red seabream iridovirus (RSIV) vaccine in red seabream, Pagrus major

Fish and Shellfish Immunology, 2006
A formalin-inactivated virus was previously found to be efficient in protecting fish against challenge with red seabream iridovirus (RSIV), a DNA virus belonging to the Iridoviridae family. In the present study, we determined the amount of the virus in the vaccine in terms of the number of copies of the gene for the major capsid protein (MCP) gene by ...

Quantitative change of red seabream iridovirus (RSIV) in rock bream Oplegnathus fasciatus, following Poly(I:C) administration

Aquaculture International, 2014
Serious economic losses due to red seabream iridovirus (RSIV) infection have occurred in fingerlings and market-sized rock bream Oplegnathus fasciatus in Korea. Previously, it was demonstrated that fishes immunized with a live fish RNA virus following polyinosinic–polycytidylic acid [Poly(I:C), an inducer of interferon (IFN)] administration were ...

Field trial tests of FKC vaccines against RSIV genotype Megalocytivirus in cage-cultured mandarin fish (Siniperca chuatsi) in an inland reservoir

Fish and Shellfish Immunology, 2013
Megalocytiviruses are one of the most important causative agents in finfish industry in China, Japan and South East Asia. The viruses are mainly composed of ISKNV, RSIV and TRBIV genotypes. Among them, ISKNV genotype isolate is the most important causative agent in mandarin fish industry in South China. Since its first occurrence in mid-1990s in China,

Development of single nucleotide polymorphism (SNP) application for detection and genotyping of RSIV‐type megalocytiviruses

Journal of Fish Diseases, 2021
AbstractRed sea bream iridovirus (RSIV) belonging to the genus Megalocytivirus of the family Iridoviridae is the cause of serious mass mortality of cultured marine fishes. RSIV‐type megalocytiviruses show extremely high nucleotide sequence identities. Thus, epidemiological studies on this virus are limited.

Analysis of the transcriptomic profiles of Mandarin fish (Siniperca chuatsi) infected with red sea bream iridovirus (RSIV)

Microbial Pathogenesis, 2023
Red sea bream iridovirus (RSIV) belongs to the family Iridoviridae, genus Megalocytivirus, which could widely infect marine fish, causing diseases and huge economic losses. Now it has been reported that RSIV was also detected in diseased mandarin fish.
