Effect of Vaccination with Refined Components of the Organism on Infection of Mice with Mycobacterium leprae

Abstract
Only native products of Mycobacterium leprae , whether cell wall, cytosol, or membrane derived, can confer protective immunity against challenge in the mouse footpad. Previously, recombinant proteins were shown to be ineffective. The cell wall skeleton—the mycolyl-arabinogalactan-peptidoglycan complex—devoid of proteins is not protective.
