Abstract
- The kinetics of the footpad response of bacillus Calmette-Guérin (BCG)-infected mice to soluble BCG antigens were compared in two strains of mice with different degrees of susceptibility to Mycobacterium lepraemurium. For the first 21 days the responses of the 'high-resistance' C57BL and the 'low-resistance' BALB/c to the nonpathogenic BCG were similar to that produced when the pathogenic mycobacterium was used. After 4 weeks the kinetics of the BALB/c mice changed and resembled that of the C57BL mice. The change in kinetics was compared with circulating antimycobacterial antibody levels and the response of draining lymph node cells in the antigen-specific lymphocyte transformation test. A dissociation was found between the kinetics of the delayed footpad response and the lymphocyte transformation response. Since both strains of mice are equally resistant to BCG, it appears that the delayed footpad response cannot be used as an indicator of host resistance in all mycobacterial infections.
