摘要

Objective Use quantitative realiin e polym erase chain reaction m eihod for detecting the coding gene' s expression ]evel of A g85B ,38kD a and M PT64 in M ycobacterium tuberculosis and expbre variability of their proteantigen in transcriptional level bete een the drug-resistant and the sensitive ,bete een the Beijng genotype and non-Beijng genotype and the value of use quantitative reartin e polym erase chain reaction diagnosing live M ycobacteiim tubercubsis .M ethods The specific prin ers of fbpB ,pstsl ,m pt64 and Siga were designed accoirding to GenBank database .The gene fragments were cbned to pMD18-T sin p]e vector respectively, and ream binant plaan idsweie purified and quantified spectophotm eteicalry .W e established theme1hod of detecting the expressbn of fbpB,pstsl,mpt64 by using SYBR Green I,and then selected 46 M ycobacterim tubercubsis strains and theN ontubercubsis m ycobacterk(2 ) to do study .qRT-PCR m eihod was used to detecthg 1he gene' s expressbn of fbpB ,ps1sl ,m pi64 in 46 M ycobacteriim tuber-cubsis,international standard strain H37Rv and 2 Nontubereubsismycobacterk. Results The amplification result h live M ycobacterim tibereubsis is S curve ,The deaih and Nontubereubsis m ycobacterk can' t detecting fluorescencal signal and the curve is linear.The gene's expressbn of m pt64 in diug-rssistant strains is downreguhted compare to sensitive strahs and H 37Rv,The result have statistical significance (t= 3 .093 (P<0 .01) ; t=2 .545 ( P<0 .05)) .The gene's expressbn of psisl in Beijing genoiype is downregulated compare to nornB eijng genoiype and H 37Rv,The result have statistical significance (t= 3 .093 (P<0 .01); t=2 .545 (P
