Methods: A total of 52 clinical isolated strains of M. tuberculosis L-forms were collected. rpoB gene polymorphism was analyzed by polymerase chain reaction and single-strand conformation polymorphism (PCR-SSCP) and conventional antimicrobial susceptibility test (AST). Their results were compared. Results: AST results showed that 38 of 52 clinical isolated strains were drug resistance (73.08％),while PCR-SSCP indicated 65.38％ (32/52) rpoB gene polymorphism. There was no statistic significance(χ2= 2.4914) between the 2 methods. Conclusion:Combined the application of PCR-SSCP with AST in detecting rpoB drug resistant gene polymorphism of M. tuberculosis L-form from pneumoconiosis patients with tuberculosis may have advantages at earlier diagnosis and guidance of clinical medications.展开更多

So far, it has not been established a satisfactory method for early diagnosis and studying on epidemiology for leprosy, we want to develop a molecular biological method for solving this point. Materials and methods. Based on the M. leprae gene coding groEL, 65kD and 16S rRNA, three polymerase chain reactions were developed by using plikaytis’, Woods’ and Pattyn’s procedures. It was optimized that the experimental parameters for each PCR, and a comparative study on practivity among three PCRs was also conducted for practical purpose.Results and conclusion. For detecting infection with M. leprae, all of PCRs established by us were highly sensitive and specific, but for practicl purpose, the woods’ PCR optimized by us ought to be chosen firstly.展开更多
