[Study of the reproduction conditions of the avian myeloblastosis virus for separation of the "reverse transcriptase" enzyme].

Sensitivity of eight chick lines to the avian myeloblastosis virus as the main source for RNA-dependent DNA-polymerase recovery was studied in the course of the "revertase" project. The virus (0.1 ml) was inoculated intracardially or intraperitoneally to one-day chicks, and then the virus titer was determined according to the ATP-activity. C and D-lines of the Enya-cross were shown to be most sensitive (sensitivity 75%) among the lines studied.
