detection of megalocytivirus from imported tropical ornamental fish, paradise fish macropodus opercularis.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 fish were classified as genotype ii, which includes freshwater fish isolates from southeast asian countries, closely related to infectious spleen and ...201020815332
the molecular epidemiology of iridovirus in murray cod (maccullochella peelii peelii) and dwarf gourami (colisa lalia) from distant biogeographical regions suggests a link between trade in ornamental fish and emerging iridoviral diseases.iridoviruses have emerged over 20 years to cause epizootics in finfish and amphibians in many countries. they may have originated in tropical asia and spread through trade in farmed food fish or ornamental fish, but this has been difficult to prove. consequently, mcp, atpase and other viral genes were sequenced from archival formalin-fixed, paraffin-embedded tissues from farmed murray cod (maccullochella peelii peelii) that died during an epizootic in 2003 and from diseased gouramis that had bee ...200616697343
isolation of an iridovirus from pike-perch stizostedion lucioperca.we have isolated a large virus from pike-perch stizostedion lucioperca fingerlings with no signs of disease. the biochemical structural, and serological properties of this newly isolated virus suggest that it belongs to the family iridoviridae. the virus multiplied and was cytopathogenic in several cultured fish cell lines. the virus has a dna-containing genome and is assembled in the cytoplasm. when viewed in electron micrographs, the assembly sites showed a paracrystalline array of hexagonal n ...19989696629
