Early response of mouse foot pads to Mycobacterium laprae.

abstract：:Repeated immunizations of CF1 mice with irradiated noninfectious Trypanosoma cruzi trypomastigotes resulted in partial protection against infection with live parasites. It also induced a limited number of antibody species that were reactive in Western blots with trypomastigote but not with epimastigote or amastigote p...
