The A segment of infectious pancreatic necrosis virus (IPNV)
is expressed as a polyprotein encoding three primary gene
products, VP2, NS and VP3, from a large open reading frame. The
nucleotide sequence for the A segment of the Sp isolate of IPNV
was determined. The NS protein is the putative...
Three closely related isolates belonging to the A₁ serotype of infectious pancreatic
necrosis virus (IPNV) were selected for comparison, to provide insight into the nature of
variation in the virulence of IPN viruses. Brook trout fry (Salvelinus fontinalis) were
experimentally infected with the three isolates by immersion. Cumulative mortalities over...
