Groups of school children aged 6-14 years were tested with PPDS and one of the following five antigens simultaneously, namely PPDA, PPDF, PPDG, PPDPL and PPDY, PPDS was prepared from the human tubercle bacillus, and the others were prepared from M. avium, M. fortuitum, the 'Gause' organisms, M. marinum and M. kansasii respectively. It was observed that there was some increase in induration size to PPDA, PPDG, PPDL, PPDS and PPDY with increase in age, while M. fortuitum gave a preponderance of small reactions with no increase of size with age. It was also observed that there was evidence of cross sensitization between PPDS and all the other antigens, particularly in those who had negative or doubtful reactions.
对6至14岁的学龄儿童组同时进行了PPDS和以下五种抗原之一的检测，即PPDA、PPDF、PPDG、PPDPL和PPDY。PPDS由人结核杆菌制备，其他分别由鸟分枝杆菌、偶然分枝杆菌、“高斯”菌、海分枝杆菌和堪萨斯分枝杆菌制备。观察到，随着年龄的增长，对PPDA、PPDG、PPDL、PPDS和PPDY的硬结大小有一定增加，而偶然分枝杆菌引起的小反应占优势，且硬结大小不随年龄增加。还观察到，有证据表明PPDS与所有其他抗原之间存在交叉致敏，特别是在那些反应为阴性或可疑的人中。
