title: Cell-mediated immunity to Vibrio cholerae with ribonucleic acid-protein fractions of V. cholerae L-form lysates.
abstract: Different L-form lysate vaccines of Vibrio cholerae serotypes Ogawa and Inaba and their combination along with ethyl alcohol-precipitated ribonucleic acid (E-RNA) and phenol-extracted RNA (P-RNA) fractions of V. cholerae Ogawa lysates were tested for production of cell-mediated immunity. Both E-RNA and P-RNA fractions induced an increase in leukocyte migration inhibition, macrophage migration inhibition, and macrophage aggregation. They also induced delayed hypersensitivity in rabbits. More consistent results were obtained with the P-RNA fraction.
