چکیده
St6riko, K. R. (1966). (Live foot and mouth disease vaccine for pigs.) -Bull. Off. int. Epizoot. 65, 359-360 (F.) (Bundesforschungsanstalt, Waldhaiuser Hohe, Tubingen). Strains of Types 0, A and C were modified by passage on calf kidney cells, until loss of virulence (and immunogenicity) for pigs. The time required for loss of virulence was related to the temp. (shorter at 280 or 220 than at 37°C). Completely avirulent strains gave good immunity at high doses only. Results indicate that these modified strains are not to be used for the preparation of live vaccines. Reprinted from "The Veterinary Bulletin", Vol. 37, No. 2, February, 1967.
