title: Study of the mode of action of ribosomal vaccines from Klebsiella and Streptococcus pneumoniae and their ribonucleic and protein fractions using passive immunization.
abstract: The vaccinating potency of ribosomal fractions of Klebsiella pneumoniae and Streptococcus pneumoniae as well as their ribosomal RNA and protein fractions has been studied with respect to their ability to induce cellular or humoral immunity. Experiments with transfer of serum or spleen cells from vaccinated animals have shown that anti-Klebsiella immunity is essentially cellular, while streptococcal immunity is exclusively humoral. Results have been discussed as a function of differential results for the various fractions under study.
