Walleye epidermal hyperplasia See percid herpesvirus

Walleye epidermal hyperplasia virus 1 (WEHV-1) A species in the genus Epsilonretrovirus. Causes discrete epidermal hyperplasia on the skin of walleyes distinct from the diffuse epidermal hyperplasia caused by percid herpesvirus 1. The virus is distinguishable from Walleye dermal sarcoma virus by phyloge-netic analysis of the genome.

Walleye epidermal hyperplasia virus 2

(WEHV-2) A species in the genus Epsilonretrovirus. Causes discrete epidermal hyperplasia on the skin of walleyes. Nucleotide sequence analysis shows that this virus is distinct from Walleye epidermal hyperplasia virus 1 and from Walleye dermal sarcoma virus, but the exact role played by each of the three retroviruses in pathogenesis and tumor formation remains to be determined.
