STUDIES ON THE LEPROMIN REACTION

IX. LOT TESTS OF LEPROMIN POTENCY IN LEPROSY BACILLI AND TUBERCLE BACILLI SENSITIZED ANIMALS

Abstract

The potency of 8 lots of Lepromin prepared at different times was tested in animals sensitized to leprosy bacilli and tubercle bacilli. The potency of the lots showed a similar trend in both groups of animals at 24 hours, and aside from a single lot, a similar trend was also observed at 48 hours.
The findings suggest that in view of the weak allergic response in leprosy bacilli sensitized animals and the difficulty in obtaining samples of leprosy bacilli, tubercle bacilli sensitized animals can be used for testing potency of Lepromin.
