title: [Isolation of new transforming viruses from "phenotypically transformed" Sirc cells in a medium with a low concentration of serum or calcium ions].
abstract: Possibility of rapid generation of highly transforming viruses from rabbit epithelial corneal cells (Sirc) on the basis of SSAV virus is discussed. The results of the study suggested a relationship between the phenomenon of "phenotypic transformation" with expression of cellular genes and a potential transforming activity. Sirc/SSAV phenotypic transformation was induced by cultivating of cells in a medium with low levels of serum or calcium ions. Subsequent infection of mink lung fibroblasts resulted in generation of 2 new transforming SSAV isolates which induced transformation in cellular lines permissive for SSAV replication. The foci of transformation were of various morphological patterns.
