摘要

In addition to the activities associated with migration inhibitory factor and type II interferon, two other inhibitory activities have been found in the sera of mice infected intravenously with BCG and 3 weeks later challenged intravenously with old tuberculin. Growth of three bacteria, Streptococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, and one yeast, Candida albicans, was inhibited in vitro by a factor or factors in the serum. Also, hematopoiesis of mouse bone marrow cells in a soft agar medium was suppressed by the serum.
