Abstract:

Two bacillus Calmette-Guérin (BCG)-susceptible mouse strains, BALB/c and C57BL/6, were infected intravenously with Mycobacterium intracellulare, M. avium or M. scrofulaceum and monitored during 3 months for mycobacterial replication and antibody and Th1-type cytokine production in response to cytoplasmic and secreted antigens from M. bovis BCG. Whereas initial colony-forming unit (CFU) counts of M. intracellulare and M. avium were higher in lungs than in spleen, the opposite was observed for M. scrofulaceum. Mycobacterium intracellulare was the most virulent species and its replication coul…
