Three-hundred and seventeen healthy individuals were investigated on a volunteer basis for tuberculin sensitivity using the dual-intradermal tuberculin test technique. 251 of them were in contact with dairy animals and 64.9 per cent of such people were found specific reactors. Those who were not in contact with dairy animals (66 persons) gave 65.2 per cent rate of specific reactivity. To interpret the tuberculin sensitivity reaction, non-specific reactivity must be excluded, especially in tropical countries. Positive tuberculin reaction is defined when the diameter of induration is 10 mm or more for persons in contact with dairy animals and tuberculous patients or consuming raw milk and 5 mm or more for other persons.
采用双皮内结核菌素试验技术，对317名健康个体进行了结核菌素敏感性的自愿调查。其中251人接触过奶牛，这些人中64.9%被发现为特异性反应者。未接触过奶牛的人（66人）特异性反应率为65.2%。为了解释结核菌素敏感性反应，必须排除非特异性反应，尤其是在热带国家。当与奶牛和结核病患者接触或饮用生奶的人硬结直径为10毫米或更大，其他人为5毫米或更大时，结核菌素反应呈阳性。
