title: [Detection of oncornavirus type D in continuous breast cancer cells].
abstract: An oncornavirus immunologically similar to oncornaviruses type D previously isolated from human continuous cells was detected in continuous cells of mammary cancer (SH3). The culture produces structures having densities of 1.18--1.19 and 1.22 g/ml which contain high molecular RNA (68S) and reverse-transcriptase activity. The similarity of this virus with other oncornaviruses was also demonstrated in molecular hybridization experiments.
