An attempt to localize the vaccinating power of Klebsiella pneumoniae ribosomal preparations using saccharose-gradient ultracentrifugation.


The study of the vaccinating power of ribosomal vaccines against Klebsiella pneumoniae led us to define the chemical nature which supports this protective activity. We tried to separate this support and the ribosomes by sucrose gradient ultracentrifugation. We isolated high protective membrane vesicles by this technique applied to salt-washed ribosomal… (More)
