Isolation of viral haemorrhagic septicaemia virus from muskellunge, Esox masquinongy (Mitchill), in Lake St Clair

Viral haemorrhagic septicaemia virus (VHSV) was isolated from   muskellunge, Esox masquinongy (Mitchill), caught from the NW portion   of Lake St Clair, Michigan, USA in 2  3. Affected fish exhibited   congestion of internal organs; the inner wall of the swim bladder   was thickened and contained numerous budding, fluid-filled vesicles.   A virus was isolated using fish cell lines inoculated with a   homogenate of kidney and spleen tissues from affected fish. Focal   areas of cell rounding and granulation appeared as early as 24 h   post-inoculation and expanded rapidly to destroy the entire cell  sheet by 96 h. Electron microscopy revealed virions that were 17 -  18  nm in length by 6 -7  nm in width having a bullet-shaped   morphology typical of rhabdoviruses. The virus was confirmed as VHSV   by reverse transcriptase-polymerase chain reaction.  Sequence analysis of the entire nucleoprotein and glycoprotein genes   revealed the virus was a member of the North American genotype of   VHSV; however, the isolate was sufficiently distinct to be considered  a separate sublineage, suggesting its origin may have been from   marine species inhabiting the eastern coastal areas of the USA or   Canada.    (VHS); (VHSv); (viral hemorrhagic septicemia); (viral haemorrhagic   septicaemia); (viral hemmorrhagic septicemia)
