title: [Physicochemical properties of the Teschen disease virus].
abstract: The physical stability of Teschen disease virus (TDV) was tested. It was found that 8 M urea at 37 degrees C and 0.5% Tween-20 for 1-2 hours destroyed TDV with formation of morphologically distinct subunits. The morphology of TDV virions and its subunits formed under the effect of urea and Tween-20 was studied. Sedimentation constant (120 S) and the polypeptide composition of TDV were determined. In TDV, major polypeptides (VP1 less than or equal to 4) and minor polypeptides (VP1m and VP2m) were found their molecular weights being 82,000, 67,000, 35,000, 30,000, 77,000, and 46,000 daltons respectively.
