METHOD FOR THE PREPARATION OF LIVE ATTENUATED CELLULAR-CULTURE VACCINE AGAINST FOWL PSEUDOPEST

摘要

The method is used for the preparation of attenuated cellular-culture vaccine against fowl pseudopest having high antigen content. It is made by the cultivation of strain Avium paramyxovirus-1, registered in NBIMCC under No. 2382, in cellular cultures of the permanent celullar BHK-21 line with subsequent freeze-drying by cryoprotector of 3.5% dextrane.
