研究目的：

主要目的： 1)结核病患者与健康受试者注射不同剂量EM的安全性与耐受性； 2)结核病患者中不同浓度EM皮试检出阳性率，健康受试者中不同浓度EM皮试阴性符合率。次要目的： 1)观察EM皮肤迟发性超敏反应发生、发展与消失过程； 2)为II期临床研究选择合适的剂量，将于3个剂量中选择2个剂量； 3)评估EM与同用途IGRA反应一致性； II期和III期临床研究EM与EC反应结果不一致时需以IGRA进行第三种试剂验证，样品采样需在皮试后进行，本研究进行皮试前后取样检测，评估皮试后取样是否对IGRA检测结果产生影响。

Objectives of Study：

Primary Objectives: 1.To evaluate the safety and tolerability of different doses of EM when administered to tuberculosis patients and healthy participants; 2.To determine the positive detection rate of EM skin tests at different concentrations in tuberculosis patients, and the negative compliance rate of EM skin tests at different concentrations in healthy participants. Secondary Objectives: 1.To observe the occurrence, development, and resolution of delayed-type hypersensitivity reactions to EM; 2.To select appropriate doses for Phase II clinical trials, with 2 doses to be chosen from 3 candidates; 3.To assess the consistency of reactions between EM and IGRA (which serves the same purpose); In cases of inconsistent results between EM and EC in Phase II and III clinical trials, IGRA shall be used as a third reagent for verification. Sample collection should be performed after skin tests. In this study, samples will be collected and tested both before and after skin tests to evaluate whether post-skin-test sampling affects IGRA test results.
