Characterization of gyrA and gyrB mutations associated with fluoroquinolone resistance in Mycobacterium tuberculosis isolates from Morocco

The results of this preliminary study highlight the high prevalence of FQ resistance among MDR-TB isolates in Morocco and consequently the need for rapid detection of FQ resistance once MDR-TB is confirmed to adjust treatment in a timely manner and to interrupt the propagation of more severe forms of M. tuberculosis drug resistance.
