The increase in cases of resistance and the reduced discovery of new drugs have limited progress in therapeutic control strategies against tuberculosis (TB). The first-line drug PZA has the ability to eliminate latent mycobacteria and is included in new TB treatment regimens. Despite its importance, the mechanism of action of PZA is still unclear. PZA-resistant MTB is associated with mutations in the pncA gene that affect PZAse activity. Currently, strains resistant to PZA, pncA wild-type, have been reported, suggesting the possibility of alternative resistance mechanisms. This work aims to find genes potentially related to alternate resistance to PZA, through the evaluation of the complete transcriptome of MTB-H37RV and 3 strains resistant to PZA, sequenced by NextSeq550, Illumina. The results evidenced transcriptional changes by PZA in the functional pncA strains, suggesting a transcriptional action mediated by POA. This work constitutes an important finding in the exploration of genes involved in the alternative mechanism of resistance to PZA. Among the main genes with a possible relationship to alternative resistance to PZA are lipid metabolism genes, metal regulatory proteins, transcriptional regulators, and efflux pumps.
