FIELD: veterinary biotechnology, virology, microbiology.
SUBSTANCE: invention proposes new strain of virus of classic pig plaque (CPP) that is obtained by direct passage of virulent strain CPP in gilts. The strain elicits stable infectious, antigenic and immunogenic activity. The strain is used for preparing highly immunogenic vaccine against CPP, preparing hyperimmune sera for prophylaxis of CPP and allows using antigen and serum prepared for it in serological reactions for diagnosis of CPP. The new strain can be used as a test-object for analysis of quality of biopreparations also.
EFFECT: valuable properties of strain and vaccine.
