Induction of resistance with heat-killed compact-type strains of Staphylococcus aureus against challenge with the diffuse variant of the Smith strain of Staphylococcus aureus.
Active immunization of mice with high doses of heat-killed and autoclaved vaccine of unencapsulated strains of Staphylococcus aureus, which was grown in brain heart infusion media, protected against challenge with the Smith diffuse strain of Staphylococcus aureus. These organisms were capable of absorbing the protective antibody in rabbit hyperimmune sera prepared with the Smith diffuse strain. Also, mice treated with rabbit hyperimmune sera prepared with these strains (four out of six strains) protected against challenge with the Smith diffuse strain. Protective activities of these rabbit hyperimmune sera were assumed to be essentially identical to the protective antibody induced by the Smith diffuse strain.
