STUDIES ON THE FRACTIONATION OF TUBERCULIN AND JOHNIN .2. EXTRACTION OF TUBERCULIN PROTEINS WITH PHENOL

Abstract
A highly specific johnin was prepd. by extraction and fractionation with phenol. Tests on cows artificially sensitized to Myco-bacterium tuberculosis and M. paratuberculosis showed this fraction to be more potent and more specific than the ordinary Bureau of Animal Industry johnin.
