The envelope (env) gene from avian leukosis virus subgroup J (ALV-J) strain Hc1 has been isolated, sequenced and cloned into an expression vector. The ALV-J Hc1 env gene and expressed protein are useful for development of diagnostic assays to detect Hc1-specific nucleic acid and proteins and for eliciting an immune response in chickens.

A lymphoblastoid cell line of turkey origin designated as MDTC-RP-19 and deposited under the ATCC Accession No. CRL-8135 has been found useful for the in vitro propagation of hemorrhagic enteritis virus (HEV). Cocultivation of the apathogenic strain of HEV with the cell line is useful in the production of a vaccine for protecting fowl against virulent HEV.
