Abstract
Conclusions
1. The addition of paraffin oil to killed tubercle bacilli promotes sensitization and antibody-formation in both guinea pigs and rabbits. 2. In rabbits, killed tubercle bacilli incorporated in paraffin oil produce sensitization and antibody-formation with greater intensity than BCG. 3. Twenty months after the injection of killed tubercle bacilli in paraffin oil into guinea pigs, evidence of sensitization still persists and complement-fixing antibody is present in the serum.
