Comparison between IS6110 and MPB64 Primers for the Diagnosis of Mycobacterium Tuberculosis in Bangladesh by Polymerase Chain Reaction (PCR)

The study was carried out to evaluate the efficacy of two different primers in PCR based diagnosis of tuberculosis on the basis of the time involvement, steps of PCR, cost and accuracy of results. Among 17 clinically suspected pulmonary tuberculosis patient’s (M:F 65:35) sputum samples, 12were found positive by both primers. Among 81 routine samples (sputum=12; blood=27; cerebrospinal fluid=16; ascitic fluid=12 and urine=14), 12 were found to be positive by IS6110 primer while 13 were found positive by MPB64. The result of M. tuberculosis DNA PCR in sputum, ascitic fluid, CSF and urine samples were found to be similar in both the primers used.
