Megalocytivirus infections cause serious mass mortality in marine fish in East and Southeast Asian countries. In this study the immunogenicity of crude subunit vaccines against infection by the Megalocytivirus RSIV was investigated. Three capsid proteins, 18R, 351R and a major capsid protein, were selected for use as crude subunit vaccines.

Development of red sea bream iridovirus concentration method in seawater by iron flocculation
Aquaculture, 2016Abstract Pathogen dynamics in environmental water are considered to be highly associated with the prevalence of fish disease. To examine the dynamics of red sea bream iridovirus (RSIV), which has caused serious damage in marine aquacultures in Japan, we developed a highly sensitive and quantitative method by combining the viral concentration and real-

AbstractRed sea bream iridovirus (RSIV) is the pathogen that causes red sea bream iridoviral disease. It causes a huge loss to the Japanese aquaculture industry. In 2021, outbreaks of red sea bream iridovirus occurred in South Japan. This study analysed nine whole‐genome sequences of RSIV isolated in Oita and Ehime Prefectures in 2021 using a short ...

The complement system plays an important role in immune regulation and acts as the first line of defense against any pathogenic attack. To comprehend the red sea bream (Pagrus major) immune response, three complement genes, namely, pmC1r, pmMASP and pmC3, belonging to the classical, lectin and alternative complement cascade, respectively, were ...

AbstractThis study investigated the kinetics of red sea bream iridovirus and host gene expression during infection in rock bream (Oplegnathus fasciatus), a species highly sensitive to the virus. After intraperitoneal injection of the viral solution at 104 TCID50/fish, the viral genome copy number in the spleen was 104.7 ± 0.2 and 105.9 ± 0.4 copies/μg ...

Iridovirus Infection of Cultured Red Sea Bream, Pagrus major.
Fish Pathology, 19921990年秋に初めて発生し, 1991年に西日本の主要養殖県に発生域が拡大した養殖マダイの大量斃死の原因究明を行った結果, 以下のことが明らかとなった。 1.病魚の外観は体色の黒化や褪色, 体表や鰭の出血性のスレを特徴とし, 剖検すると鯉の褪色, 鰓弁の点状出血や先端部からの出血, 囲心腔内の出血等が観察された。 2.病理組織学的には脾臓組織のほか, 心臓の心内膜下, 鰓の中心静脈洞内皮および中肋の軟骨膜に接する組織間隙, 腎臓の間質組織と糸球体に肥大球形化した細胞が多数観察されるのが特徴であった。肝臓ではその出現頻度は低かった。 3.電顕観察ではこれらの異形肥大細胞の細胞質内に平面的には6角形を呈する, 直径が200～240nmのウイルス粒子の増殖像が観察された ...

Nervous necrosis virus (NNV) and red sea bream iridovirus (RSIV) are two important pathogens that have caused acute, highly contagious, and widespread diseases among wild and cultured fish, especially at larval and juvenile stages. We discovered that the pathogenicity of NNV to the 80 days post-hatch (dph) barramundi is lower than that to the 14 dph ...

AbstractAn outbreak of a Megalocytivirus infection was found in the golden mandarin fish Siniperca scherzeri during September and October 2016, in Korea. Phylogeny and genetic diversity based on the major capsid protein (MCP) and adenosine triphosphatase (ATPase) genes showed a new strain.
