title: A new variant of Rous sarcoma virus-33 nondefective, pathogenic for rats.
abstract: Rous sarcoma virus-33 (RSV-33) belongs to RSVs that have the least number of passages beyond its isolation from chicken tumor No. 1 among all current strains of RSV. Biological characterization indicated that it was pathogenic for rats. The results of the proviral restriction enzyme analysis showed that the established rat tumorigenic cell lines were the most likely infected by the same virus having a full-length genome.
