    test in Tokyo: Hideo MAEDA (Bureau of Social Welfare and Public Health, Tokyo Metropolitan Government). 2. Contact investigation of a tuberculosis outbreak: Kenichi MIYAMOTO (Takaido Community Health Center). We have experienced a TB outbreak in integrated junior and senior high school in Tokyo. Index patient was a student with persistent respiratory symptoms for six months before diagnosis of sputum smear-positive TB. Public health center started contact investigation immediately. QFT-positive rates were high in close contacts, especially in classmates. Additionally, a student outside of contact investigation was diagnosed as TB and considered to be infected from the first patient by VNTR analysis. Therefore, public health center expanded QFT-tests to all students and teachers in this school. Finally, 9 students and 2 teachers in this school were diagnosed as sputum smear-negative TB by contact investigation. 3. Utilization of molecular epidemiological procedure in contact investigation in Kyoto City: Masahiro ITO (Public Health Center of Kyoto City) Molecular epidemiological procedure using VNTR analysis has been used for contact investigation of tuberculosis since January 2011 in Kyoto City. One hundred forty four strains of Mycobacterium tuberculosis from patients with tuberculosis were investigated and 130 strains were fully analyzed. Fourteen clusters were found and the number of strains included in the cluster was ranged from two to 11. Epidemiological relationship between patients in one cluster was found, however, significant relationship in another clusters was not demonstrated. It was suggested that VNTR analysis is useful for molecular epidemiological analysis of tuberculosis. 4.
