Type C virus production by a continuous line of pig oviduct cells (PFT)

Late passages of the PFT porcine oviduct cell line spontaneously release a typical type C virus antigenically related to the type C virus released from the PK(15) porcine kidney cell line. The PFT virus was non-infective for a large variety of cell lines. Type C virus can also be induced by BrdU treatment from earlier passages of the PFT cell line.
