Aquareovirus C

The golden shiner virus is an aquatic virus that infects a bait fish known as the golden shiner and to a lesser extent, aquatic animals like crustaceans and molluscs. About 6 virus species have been identified in this genus since the late 1970s.[1] It causes death through a hemorrhagic shock. Symptoms include bleeding from the back eyes and the head. The virus is 70 nm in diameter and replicates best at 20-30 degrees Celsius. The virus has properties similar to those of the pancreatic necrosis virus. This could mean that golden shiners are more susceptible in the summer.[2]

Virus genome

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