Abstract
To compare the performance of the BacT/ALERT PZA kit (BioMerieux, Marcy l'Etoile, France) with the radiometric BACTEC 460TB PZA test (Becton–Dickinson method) for testing Mycobacterium tuberculosis susceptibility to pyrazinamide. A total of 50 M. tuberculosis strains were tested. Thirty of these strains had been previously considered pyrazinamide-susceptible and 20 pyrazinamide-resistant by BACTEC 460TB. Final overall agreement was 100%. Time needed for the susceptibility test was 6.69 days for the BacT/ALERT PZA kit versus 8.07 days for the BACTEC 460TB PZA test. BacT/ALERT PZA test is an excellent alternative to BACTEC 460TB for pyrazinamide susceptibility testing.Keywords
