[A comparative study of the immunogenicity of a bacterial mass and of the cell membranes of Vibrio cholerae grown in vivo and in vitro].

The comparative study of the immunogenic and protective properties of V. cholerae, grown in vivo and in vitro, and cell walls and lysates obtained from these organisms. In the mouse protection test the efficacy of preparations obtained from vibrios grown in vivo did not exceed that of the preparations obtained from V. cholerae agar cultures.
