A total of 137 adult Panamanians were skin-tested with 2 standard tuberculins (PPD-S and PPD-T) and 3 antigens prepared from atypical mycobacteria: PPD-B (Battey), PPD-Y (M. kansasii), and PPD-X (M. xenopi). PPD-T elicited fewer doubtful reactions than PPD-S. Both PPD-B and PPD-X, when used as antigens in dual testing, greatly reduced the number of doubtful reactions.
总共137名成年巴拿马人接受了2种标准结核菌素(PPD-S和PPD-T)以及3种由非典型分枝杆菌制备的抗原的皮肤试验:PPD-B(巴蒂)、PPD-Y(堪萨斯分枝杆菌)和PPD-X(蟾蜍分枝杆菌)。PPD-T引发的可疑反应比PPD-S少。当PPD-B和PPD-X用作双重检测的抗原时,都大大减少了可疑反应的数量。
