Abstract

Extract

Using data from the experiment described in Part I of this paper (Davidson, 1965), the short thermal subcutaneous tuberculin test was critically evaluated, and, at the same time, the performances of Australian tuberculin (derived from human strains of tubercle bacilli 100,000 T.U. per ml) and Canadian tuberculin (derived from bovine strains of tubercle bacilli 20,500 T.U. per ml) were compared.
