title: [Sensitivity testing of chick embryo subcultures to the Newcastle disease virus].
abstract: A total of five passages of subcultures were produced from chick embryos with the use of a medium enriched with a 10 per cent solution the previous passages of the cells. The form, number, and size of the plaques obtained at the cultivation of the Newcastle disease virus in the cells of the various passages of the subcultures did not differ. The virus production per cell did not also change substantially with the increase in the number of subculture passages.
