Abstract
A Mycobacterium avium ssp. paratuberculosis purified protein derivative (PPD) was produced and the biologic activity evaluated in sensitized guinea pigs. The PPD when adjusted to a protein concentration of 1mg/ml induced a delayed-type hypersensitivity response comparable to USDA Johnin OT 133-8707.
