Production of a Mycobacterium avium ssp. paratuberculosis purified protein derivative (PPD) and evaluation of potency in guinea pigs

Biologicals. 2002 Jun;30(2):93-5. doi: 10.1006/biol.2002.0321.

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.
