title: [Activation of proteinases and acid phosphatase in swine leukocytes infected with the swine classical plague virus].
abstract: The activities of proteinases active at neutral pH and of acid phosphatase increases after freezing and defrosting and hypotonic shock in porcine leukocytes in vitro infected with the classical hog cholera virus in comparison with intact cells. The enzymes in the cells from animals both immune and nonimmune to hog cholera were activated upon infection with both virulent and vaccine strains of the virus. No proteinase activity was detected in the culture medium in which infected porcine leukocytes were cultured. Possible pathological reactions of a cell to viral infection are discussed.
