Polymarase Chain Reaction may be the better method of detecting M.tuberculosis than other methods and lead us to carry out a series of research on this problem. This thesis is composed of five parts:(1)systematic evaluation for the first time of the ability of five defferent PCR methods to detect M. tuberculosis;(2) using the endonuclease and southern blot by a radioactive and a nonradioactive labeled probe, to confirm the specificity of the PCR products and to analyse the sensitivity of detection by southern blot method using digoxigenin-labeled probe;(3) evaluation of acid-fast staining, bacterial culture and PCR for the detection of M. tuberculosis in sputum, pleural and peritoneal effusion samples;(4) The feasibility of PCR for detection of M tuberculosis on formalin-fixed paraffin embedded tissues;(5) 26 cases of sarcoidosis were retrospectively studiedwith PCR for M. tuberculosis and nontuberculosis Mycobacterium and the problems on histopatholoical diagnosis of sarcoidosis are discussed.
