[Extraction and freeze-drying of herpes virus C3-1 isolated from turkeys].

Possibilities for producing dried preparations of turkey herpes virus C3-1 by use of various ultra-sound desintegrator-systems and different ways of processing the cell suspensions containing the virus were studied. It was established that cell-less virus of a 1.5 to 2 log smaller quantity than the initial virus containing cell suspension can be produced by ultrasound generator with an indirect action -- a vibrating membrane, which transmits the impulses through a liquid medium and the container's walls on the object.
