Toward precision detection of pyrazinamide resistance: critical concentration assessment and rapid molecular method validation

This study evaluated broth microdilution (BMD) and fluorescence PCR melting curve analysis (MeltPro MTB/PZA, targeting pncA mutations) for detecting pyrazinamide (PZA) resistance-associated mutations in rifampicin-resistant tuberculosis (RR-TB). PZA susceptibility was assessed in RR-TB isolates from...
