The importance of that study was that it was the first study to document the presence of PRV in salmon in the Pacific northwest. It definitely could have informed a lot of the work moving forward. However, subsequent to that, there were other studies by other groups on that particular virus. My own program continued to work with different sets of samples to better understand the potential of that virus to cause disease and the prevalence of the virus in our natural wild populations.
Our work has shown that the virus is likely capable of causing disease in both chinook salmon and Atlantic salmon. The same kinds of disease processes that we see in other parts of the world have been seen in our salmon in aquaculture in British Columbia, and we do see some similar types of pathological changes in our wild chinook salmon populations.
Recently, we have a paper coming out that shows PRV is one of the agents most strongly associated with population-level impacts in chinook and coho salmon.
