Complement reaction in leprosy. Activation by potassium Iodide

Abstract

I n 1929, while we studied the effects of the administration of potassium iodide to lepers for the purpose of obtaining a complement reaction (the fat free bacillus of Deycke being used as antigen) we had occasion to note that, almost all cases were activated, so that individuais with a previous negative serum reaction, in spite of the existence of some syrnptoms of leprosy, became positive cases.
