Uptake of channel catfish virus from water by channel catfish and bluegills.

Radiolabeled channel catfish virus entered the gills of juvenile channel catfish (Ictalurus punctatus) and was then concentrated in the gut and the liver over 48 hours. Diminution of radioactivity was not detected in these tissues over the course of the experiment. Bluegills (Lepomis macrochirus) were capable of clearing the virus during a period of 48 hours. [3H]Thymidine alone had a different distribution in the channel catfish than did labeled virus.
