title: Ability of the phenolic glycolipid-I antigen of M. leprae to elicit a positive Mitsuda response in the armadillo (Dasypus novemcinctus).
abstract: Three lepromin-positive armadillos and three lepromin-negative armadillos were tested intradermally with 100 micrograms of phenolic glycolipid-I (PGL-I) in 0.1 ml of normal saline. Positive delayed-hypersensitivity granulomas at 21 days in the lepromin-positive animals and negative responses in the lepromin-negative animals were obtained. These observations suggest that purified PGL-I is capable of eliciting cell-mediated immune or delayed-hypersensitivity responses in animals sensitized to Mycobacterium leprae.
