School children in lagos were tested with PPD-S and one of the following tuberculins simultaneously namely PPD-G, PPD-A, PPD-Y, PPD-F, and PPD-PL. The tuberculins were prepared from Mycobacterium tuberculosis, the Gause organism, M. avium, M. Kansasii, M. fortuitum and M. marinum respectively. It was found that for the different antigens, among those children who had indurations from 0 to 4 mm those small sized reactions wer generally due to sensitization by opportunist mycobacteria. In contrast to this, among those who had indurations over 10 mm, the reactions were due to sensitization by the human tubercle bacillus. Testing of patients with bacteriologically and radiologically proved tuberculosis showed that practically all of them reacted in an expected manner, i.e. PPD-S elicited larger reactions than PPD-Y, PPD-A, PPD-G, PPD-LL and PPD-F.
对拉各斯的学童同时进行了PPD-S和以下结核菌素之一的检测，即PPD-G、PPD-A、PPD-Y、PPD-F和PPD-PL。这些结核菌素分别由结核分枝杆菌、高斯菌、鸟分枝杆菌、堪萨斯分枝杆菌、偶然分枝杆菌和海分枝杆菌制备。结果发现，对于不同的抗原，在硬结为0至4毫米的儿童中，那些小尺寸反应通常是由机会性分枝杆菌致敏引起的。与此形成对比的是，在硬结超过10毫米的儿童中，反应是由人结核杆菌致敏引起的。对经细菌学和放射学证实患有结核病的患者进行检测表明，实际上他们所有人的反应都符合预期，即PPD-S引起的反应比PPD-Y、PPD-A、PPD-G、PPD-LL和PPD-F更大。
