Evaluation of PCR in Detection of Mycobacterium tuberculosis from Formalin-Fixed, Paraffin-Embedded Tissues: Comparison of Four Amplification Assays
1 Jun 1998
Abstract excerpt
We compared the sensitivities and specificities of four nested PCR assays for the detection of Mycobacterium tuberculosis from formalin-fixed, paraffin-embedded tissues. Thirty-seven autopsy samples from human immunodeficiency virus-positive patients were analyzed: 15 were M. tuberculosis positive, 11 served as negative controls, and 11 were Ziehl-Neelsen positive without cultural confirmation of M. tuberculosis....
