FIELD: microbiology. SUBSTANCE: new strain of classic swine plague virus multiplicating at high infectious activity 5.0-6.5 lgBOE5 0/ml in transplanted cell cultures and showing high thermoresistance as compared with that of the strain ЛК-ВНИИВВиМ and retaining immunogenicity. Strain "ЛК-К" classic swine plague is deposited in Collection of ВНИИВВиМ at N 1842. Strain is obtained by limit dilution cloning method and selection of obtained clones by trait - multiplication at the high titer in transplanted cell cultures. Cloning is carried out by limit dilution method for 5 passages. As a result, the clone is isolated accumulating in transplanted cell cultures at titers 5.5-7.0 lgBOE5 0/ml. Stability of this trait is retained for 50 passages (observation period). Obtained virus clone is designed as "ЛК-К". EFFECT: preparing new strain indicated above. 1 tbl
