Fig. 2From: Antigen-specific assessment of the immunological status of various groups in a leprosy endemic regionAntigen-specific responses of leprosy patients, stratified by Ridley-Jopling classification. Sera from leprosy patients characterized as a. TT; b. BT; c. BB; d. BL or e. LL were analyzed for antibodies against LID-1 (IgG), NDO-LID (IgG and IgM), NDO-HSA and PGL-I (IgM). Each point represents the EI of an individual serum sample. The mean EI is represented by the horizontal line. The traced horizontal line is threshold for determining a positive result (EI = 1.1)Back to article page
