title: [Physicochemical properties of Teschen disease virus RNA].
abstract: The specific infectivity of virion RNA of teschen disease virus in a sensitive PP cell culture was 4-5 lg TCD50/ml per 1 microgram RNA. When virion RNA was inoculated into cell cultures insusceptible to the native virus, the virus replicated to a titre of 2.0-3.5 lg TCD50/ml. The molecular weight of virion RNA determined by two independent methods was 2.7 x 10(6) daltons. Tm calculated from the curve of virion RNA melting temperature was 57 degrees C. The double-stranded replicative form of RNA recovered from virus-infected PP cells was shown to have sucrose gradient sedimentation coefficient of 20 S. The specific infectivity was 2-3 lg TCD50/ml per 1 microgram of RNA.
