Protective ability of Salmonella ribosomal protein and RNA in inbred mice.


Ribosomal vaccines prepared from Salmonella typhimurium were effective immunogens in A/J, C3H/HeDub, and C3H/HeJ mice. Purified ribosomal components were also tested as immunogens in the inbred mice. Protein isolated from a Salmonella ribosomal fraction could protect all three mouse strains. Although purified RNA was shown to be protective for A/J and C3H/HeDub mice, it was not protective for C3H/HeJ mice. Protective immunity could be induced in A/J and C3H/HeDub mice by various immunostimulants. Immunity in C3H/HeJ mice, however, could only be induced by Salmonella ribosomes or protein isolated from the Salmonella ribosomal fraction.
