| Resumo: |
Double repetitive element (DRE) PCR amplification is a simple Mycobacterium tuberculosis typing method, however amplification failure or poor resolution of bands commit its efficacy. In order to verify if whether or not these features could be minimized by improving DNA extraction procedures or Taq polymerise quality, DRE-PCR was performed on 24 M. tuberculosis DNA samples extracted by heat-shock, mechanical and enzymatic methods applying conventional and hot start Taq pol. We demonstrated that when dealing with the Mycobacterium tuberculosis DRE-PCR typing method, Taq pol of better quality might be more important to improve amplification than the DNA extraction method.
