Detection of megalocytivirus from imported tropical ornamental fish, paradise fish Macropodus opercularis [PDF]
Diseases of Aquatic Organisms, 2010 Megalocytivirus was detected from paradise fish Macropodus opercularis imported from Indonesia. Four of 11 fish (36%) in 2006 and 40 of 117 fish (34%) in 2008 were found to be PCR-positive for megalocytivirus. Phylogenetic analysis based on partial major capsid protein (MCP) gene nucleotide sequences revealed that the sequences detected in paradise ...

Megalocytivirus Induces Complicated Fish Immune Response at Multiple RNA Levels Involving mRNA, miRNA, and circRNA. [PDF]
Int J Mol Sci, 2021 Megalocytivirus is an important viral pathogen to many farmed fishes, including Japanese flounder (Paralichthys olivaceus). In this study, we examined megalocytivirus-induced RNA responses in the spleen of flounder by high-throughput sequencing and integrative analysis of various RNA-seq data.

Transboundary and Emerging Diseases, Volume 68, Issue 3, Page 1550-1563, May 2021., 2021 Abstract In late 2018, unusual patterns of very high mortality (>50% production) were reported in intensive tilapia cage culture systems across Lake Volta in Ghana. Samples of fish and fry were collected and analysed from two affected farms between October 2018 and February 2019. Affected fish showed darkening, erratic swimming and abdominal distension

Improved multiplex PCR method for the detection of diverse Megalocytivirus in the Korea [PDF]
, 2021 Megalocytivirus is a genus of piscine viruses that belongs to the Iridoviridae family, and this family comprises red seabream iridovirus (RSIV), turbot reddish body iridovirus (TRBIV), and infectious spleen and kidney necrosis virus. RSIV causes high mortality and economic losses in the rock bream (Oplegnathus fasciatus) Korean aquaculture industry ...

Detection of spatiotemporal variation in ranavirus distribution using eDNA
Environmental DNA, Volume 2, Issue 2, Page 210-220, April 2020., 2020 We investigated the presence of ranaviruses in wetlands in Ontario, Canada by using eDNA. Our results showed a widespread presence of ranavirus in southern Ontario with seasonal variability. Habitat occupancy modeling showed that wetland size influenced ranavirus occupancy while sampling date influenced the probability of detection.

Evolution of DNA ligases of Nucleo-Cytoplasmic Large DNA viruses of eukaryotes: a case of hidden complexity [PDF]
, 2009 Background Eukaryotic Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) encode most if not all of the enzymes involved in their DNA replication. It has been inferred that genes for these enzymes were already present in the last common ancestor of the NCLDV ...
