Abstract:
Differential display-PCR was used to clone the differential expressed genes between Mycobacterium tuberculosis virulence strain H37Rv and its avirulent mutant H37Ra. All of different genes were cloned, sequenced and some were analyzed by Northern-blotting. Two cDNAs that appeared to be expressed in H37Rv, but not in H37Ra, were cloned and sequenced. Rv0170, and Rv1894c, code for proteins with unknown functions. The two gene were present in H37Ra, but not expressed. These results show that mRNA DD methodology can represent a potential tool for investigation of M. tuberculosis gene expression.
