title: [Morphologic changes in cultures of different tissues exposed to the toxins of C1. perfringens types B, C, E and F].
abstract: There were revealed morphological peculiarities of the action of C1. perfringens toxins, types B, C, D, E and F on the cultures of fibroblasts of chick embryo, amniotic cells and intestinal tissue. The toxin type B was characterized by a marked vocuolization of the cell cytoplasm; the action of the toxin of type C was expressed in the swelling of the nuclei and the lysis of the chromatine substance, the toxin of type E casued kariorhexis, and the toxin of type F--hyperchromatosis of the nuclei. All the cultures proved to be insensitive to the toxin of type D. Peculiarity of the morphological affection of the cells permitted to differentiate toxin of type B in the cultures of the fibroblasts  of chick embryo, whereas the toxins of types C, E and F--in the cultures of the amniotic cells under control of the reaction of neutralization with the homologous antitoxic sera.
