Two Eco RI fragments from Salmonis herpesvirus 2 (Oncorhynchus masou virus) have been sequenced. Clone pOE 150 coded for a protein homologous to ORF.68 from Ictalurid herpesvirus 1 (channel catfish virus). Clone pOE 21 coded for a protein homologous with ORF 46 from the same virus. No homology was found with mammalian herpesviruses.
