Transcription profile of an azole resistant mutant of Mycobacterium truberculosis


ABSTRACT: We used DNA microarrays to detect differentially expresses genes in a spontaneous mutant of Mycobacterium tuberculosis H37Rv resistant to azoles. We identified three adjacent upregulated genes encoding a transcription regulatory protein and two membrane proteins belonging to the family of RND efflux transporters. Hybridization were performed using RNA extracted from three different biological samples coming from cultures grown in mid-exponential phase.

Tuberculosis (TB) remains the leading cause of mortality due to a bacterial pathogen, Mycobacterium tuberculosis. Moreover, the recent isolation of M. tuberculosis strains resistant to both first- and second-line antitubercular drugs (XDR-TB) threatens to make the treatment of this disease extremely difficult and becoming a threat to public health worldwide. Recently, it has been shown that azoles are potent inhibitors of mycobacterial cell growth and have antitubercular activity in mice, thus f  ...[more]
