Information about the prevalence of different virus strains is important for the fish farmers,fish health services, fish health autorities and vaccine companies to combat and control the disease, The molucular biology of IPNV is well known, but a genetic characterisation of the virus causing disease outbreaks and the localization of gene sequences of importance for virulence has not been performed systematically. Tissue samples collected from sea farms experiencing clinical IPN will be examined for the presence of IPNV, and in the case of detection of virus, the gene encoding the major capsid protein VP2 will be sequenced. Information on virus variants will be associated with factors on management, environment and fish status in risk factor analyses.
The principle objective of this project was to obtain knowledge on the genetic variation of IPNV and associated risk factors for disease outbreaks. This project was a follow-up of a previous project which was restricted to studies of IPNV in sea farms. sub-goals:
1. Characterize the nucleotide sequences of IPNV encoding viral proteins with documented
strain variations (Segment A) in samples from diseased fish and carriers.
2. Describe how outbreaks characteristics and potential risk factors for outbreaks are related to different virus variants.
3. Compare gene sequences of IPNV (Segment A) in hatcheries and in sea farms receiving
smolt from the respective hatcheries and relate virus variants to rearing conditions.
