* HK13 was derived from a PRV-1 infected fish. Apart from originating from an infected fish, this cell line was not used in the in vitro screening of PRV-1 containing head kidney and red blood cell homogenates. ** Cell lines also evaluated by others for PRV-1 susceptibility. ¹ Cell lines informally shared among researchers. ² Cell lines are in curated culture collections. ³ Newly developed cell lines from this work.
