According to a study from Vitoria, Brazil, "We evaluated the ability of a PCR assay to identify Mycobacterium tuberculosis complex (MTBC) from positive BACTEC (R) 12B broth cultures. A total of 107 sputum samples were processed and inoculated into Ogawa slants and BACTEC (R) 12B vials." "At a growth index (GI) >= 30, 1.0 ml of the 12B broth was removed, stored, and assayed with PCR. Molecular results were compared to those obtained by phenotypic identification methods, including the BACTEC (R) NAP method. The average times required to perform PCR and NAP were compared. Of the 107 broth cultures evaluated, 90 were NAP positive, while 91 were PCR positive for MTBC. Of...
