One hundred fifty eight leprous patients and children apparently healthy from BabaBaghi leprosarium in Tabriz and two healthy individuals from another city were tested to estimate their response to allergic reaction with lepromin, paratuberculose particulate antigen and paratuberculin P.P.D. From 84 patients with clinical form LL, 45.24% showed Fernandez positive reaction with lepromin, 81.57% with paratuberculose particulate antigen and 86.85% with paratuberculin P.P.D. only 3.51% of them had positive Mitsuda reaction but with the above allergens 71.42% should positive reaction. From 27 children apparently healthy tested 74.07% had positive Fernandez reaction but with paratuberculin 96.26% showed positive reaction after 72 hours. In Mitsuda test with lepromin 81.48% and with paratuberculin 44.44% of them showed positive reaction. One of the control healthy individual who was tuberculin positive showed negative reaction with paratuberculin. It seem that there is a great antigenic relationship between M. leprae and M. paratuberculosis. Authors' summary
