[Comparative study of the diagnostic value of new cholera eltor bacteriophages ctx+, ctx-, and KhDF-3, 4, and 5].

The comparative evaluation of the diagnostic value of new cholera eltor bacteriophages ctx+ and ctx-, as well as monophages X[symbol: see text]-3, 4, 5, demonstrated their high activity and specificity. Using of these bacteriophages epidemic potential of 95% Vibrio cholerae eltor strains ctx+ and 84.5% of V.

[Effect of difenin on taurine binding by subcellular fractions of nerve cells].

The binding of 14C-taurine by subcellular fractions of rat brain cortex was studied in vitro. The binding was discovered to be more marked in the presence of phenytoin. The stimulant effect of phenytoin was found to be dose-dependent.

[Postvaccinal dysentery immunity studied on the model of ligated loop of the small intestine of rabbits].

Chemical (detergent) antigens administered intraintestinally or intravenously to rabbits were applied to reproduce postvaccinal immunity to experimental shigellosis. There was noted an increase of the antibody level in the serum, an intensification of its preventive proerties, and the absence of dilatation of the isolated loops of the small intestine after the administration of the corresponding dysentery culture. Oral immunization of rabbits with the detergent antigen sorbed on ionexchange resin also led to immunity.
