Antigen Analyse of Human Leprosy Bacilli and Murine Leprosy Bacilli for Intradermal Reaction

In order to analyse the intradermal reaction between human leprosy bacilli and murine leprosy bacilli, human leproso bacilli and tubercle bacilli, murine leprosy bacilli and avian tubercle bacilli, experiment for passive transfer was performed, by using peritoneal cells with hypersensitivity to tuberculin type in guinea pigs.Results were obtained as follows:1. Peritoneal exudate cells from sensitized donor guinea pigs of human leprosy bacilli, murine leprosy bacilli, tubercle bacilli and avian tubercle bacilli were capable of transfer to normals recipients. The intradermal reaction of recipients were a similar specificity to that of donor.2. The specificity of human leprosy bacilli was different from that of murine leprosy bacilli.3. The human leprosy bacilli had a similar specificity to that of tubercle bacilli.4. The specificity of murine leprosy bacilli was essentially the same as that of avian tubercle bacilli.
