[Molecular epidemiologic study of tuberculosis--a study on isolates of M. tuberculosis in southern half of Osaka Prefecture].

Restriction fragment length polymorphism, RFLP or DNA fingerprinting technique provides a very useful tool for the study of epidemiology of tuberculosis transmission in human. We performed RFLP analysis with the IS6110 insertion sequence of the organisms isolated from culture-positive patients who visited our Hospital during the period from January to December 2001. Our Hospital covers patients living in southern half of Osaka Prefecture including a part of Osaka City, which is the highest TB prevalence area in Japan.
