Abstract

The comparative study of the preparations of V.cholerae hemolysins of different serovars with the use of continuous cell lines CHO-K1, Vero, Hela, L-929 was carried out. The preparations of hemolysins isolated from such strains as V.cholerae 569B, V.eltor 9949, V.cholerae O-mut 461/67-34 differed in their biological activity on experimental animal models and had different cytotoxic activity. The preparations exhibiting no activity when tested in vivo (V.cholerae and V.eltor hemolysins) were cetotoxins, but in lower doses (1000 and 100 times respectively) than the preparation of V.cholerae O-mut hemolysin, active in vivo. Hemolysins induced the formation of anticytotoxic antibodies in low titers.
