Ciba Foundation Symposium on Experimental Tuberculosis: Bacillus and Host, with an Addendum on Leprosy.

This volume contains 28 separate articles on the subjects of tuberculosis and leprosy. These papers were presented as a part of the Ciba Foundation Symposium on the tubercle bacillus and the reaction of tissues to tuberculous infection. Each paper is followed by the remarks of each of the discussants.

The enumeration of the papers and the authors is not practical. However, in this volume the following general subjects are covered. The nature and biological activity of the chemical substances isolated from the tubercle bacilli; the biochemical factors which are involved in resistance to infection by tubercle bacilli; the antigenic activity of various chemical fractions of tubercle bacilli; the nature of tuberculin hypersensitivity; the nature of immunity to tuberculosis, and the influence of a variety of factors on resistance and immunity to tuberculosis. Finally, there are four papers on leprosy, which summarize some of the information on the host parasite relationship
