ds RNA viruse Family Reoviridae Genus Aquareoviruses Species Golden shiner virus

The golden shiner virus is an aquaviruse that infects a bait fish known as the golden shiner and to a leser extent,aquatic animals like crustaceans and mulluscs.About 6 virus species have been identified in this genus since the late 1970s.(Attoui et al. 2002) It causes death through a haemorragic shock.Symptoms include bleeding from the back eyes and the haed. The viruse is 70nm in diameter and replicates best at 20-30 degrees celcius. The virus has properties similar to thase of the pancreatic necrosis virus.This could mean that golden shiners are more susceptible in the summer.(Schwedler, Plumb 1982)

Viruse genome The genome is packed into the core and is encased in a double layered icosahedral capsid that is simlar to the orthoreovirus capsid. This genome has 11 segments like the rotaviruse.Each genome has a 5`end motif of (GUUAUU) and (UUCAUC)motif at the 3`end. There are 11 openreading frames.Segments 1-3 encode viral proteins (VP)1-3, segments 4,7,8,9and 11 code for non-structural proteins, segments 6 and 10 are for coding outer-capsid proteins.Lastly, segment 5 encodes an enzyme protein NTPase.
