Abstract
Method of propagating viruses that replicate in embryonated eggs or in primary cultures of chicken embryo cells on an immortal, virus-free, contact-inhibited, and non-oncogenic chicken embryo cell line. The method supports replication of avian viruses of the Birnaviridae, Coronaviridae, Herpesviridae, Orthomyxoviridae, Paramyxoviridae, Picornaviridae, Polyomaviridae, Poxviridae, and Reoviridae families. The immortal cell line of the present invention supports replication of swine influenza virus, for instance. The cell line is useful for virus isolation diagnostic assays and for propagating virus suitable for live or killed vaccines.
