Index case (S.K.) was a postgraduate in one institute of Tohoku University and was diagnosed as pulmonary tuberculosis by regular health check-up. Examinations of sputa indicated Gaffky 6 on smear and +3 in culture, respectively. Five months after the diagnosis of the index case, a professor (O.K.) who was teaching S.K. in the same institute was diagnosed as tuberculosis by the chest X-ray survey. One month later, another postgraduate (M.J.) studying in other institute was found to affected with tuberculosis by regular health check-up. Since two institutes were distant from each other, it seemed that neither S.K. nor O.K. had an opportunity to contact with M.J. It was revealed, however, that two postgraduates received some lecture in the same classroom twice a week. Considering all these facts, three cases presented here are regarded as tuberculosis outbreak in the university.
首例病例（S.K.）是东北大学某研究所的一名研究生，通过定期健康检查被诊断为肺结核。痰液检查显示涂片为加夫基6级，培养为+3级。首例病例确诊五个月后，在同一研究所教S.K.的一位教授（O.K.）通过胸部X光检查被诊断为肺结核。一个月后，另一名在其他研究所学习的研究生（M.J.）通过定期健康检查被发现感染了肺结核。由于两所研究所相距甚远，似乎S.K.和O.K.都没有机会与M.J.接触。然而，据透露，这两名研究生每周在同一教室听两次讲座。考虑到所有这些事实，此处呈现的三例病例被视为该大学的结核病暴发。
