Abstract

The significance of the apparent occurrence of Egtved virus in cod cannot be fully evaluated at the moment. It is our feeling, however, that cod probably does not represent a new host for the virus, but that the virus isolation more likely resulted from contamination of a cod surface or a cell culture with Egtved virus of fresh water origin. The fact that CPE originally was induced in cell cultures only during the second subculture indicates that the virus was present at extremely low concentration. The host spectrum for Egtved virus in natural infections so far has been found to include only pike( Esox lucius )in addition to salmonid fish of different species (Ahne and Thomsen, 1985).
