ABSTRACT: The Australian native marine fish species, silver sweep Scorpis lineolata, is susceptible to the megalocytivirus Infectious spleen and kidney necrosis virus (strain DGIV-10) obtained from a freshwater ornamental fish, dwarf gourami Trichogaster lalius. This was demonstrated by direct inoculation and through cohabitation. Transmission by cohabitation was also demonstrated from inoculated freshwater Murray cod Maccullochella peelii to euryhaline Australian bass Macquaria novemaculeata and to marine silver sweep. The virus was also transmitted from infected marine silver sweep to euryhaline Australian bass and then to freshwater Murray cod. This study is the first to demonstrate the virulence of a megalocytivirus derived from ornamental fish in an Australian marine species and the first to show a feasible pathway for the exchange of megalocytiviruses between freshwater and marine finfish hosts. These results demonstrate that megalocytiviruses from freshwater ornamental fish have the potential to spread to diverse aquatic environments.
