Pyrazinamide resistance in Mycobacterium tuberculosis fails to bite? Institute of Tropical Medicine
In contrast to most other antimycobacterial drugs where--particularly in multidrug-resistant (MDR) strains--a limited number of resistance mutations dominate, pyrazinamide (PZA) resistance associated mutations remain highly diverse with limited clustering. This apparent lack of evolutionary selection for successful PZA resistance mechanisms deserves attention. A clear understanding of the epidemiology of PZA resistance acquisition and spread ...
