The passive transfer of rabbit anti-mycobacterial immunoglobulins was directed against either living or soluble extracts of Mycobacterium tuberculosis strain H37Rv, which promotes the multiplication of the BCG strain of M. tuberculosis in the spleen of mice infected with low doses of this latter strain. This enhancing effect was reduced significantly when antisera were absorbed with living BCG. Moreover, such treatment led to the removal of all hemagglutinating antibodies when antisera were
