The iridovirus from dwarf gourami (DGIV-2004), red sea bream iridovirus (RSIV) and epizootic haematopoietic necrosis virus (EHNV) were tested in PCR with Megalocytivirus genus-specific MCP primers C50/C51, MCP primers for the DGIV-group within Megalocytivirus C82/C83 and MCP primers for EHNV M151/M152.
