pubmed:abstractText |
For the detection of Mycobacterium tuberculosis by PCR, the IS6110 sequence was used. A modified target was constructed by insertion of 56 nucleotides in the IS6110 insertion element of Mycobacterium bovis BCG. This modified insertion sequence was integrated into the genome of Mycobacterium smegmatis, a mycobacterium species which does not contain the IS6110 element. When DNA from the modified M. smegmatis 1008 strain was amplified with IS6110-specific primers INS1 and INS2, a band of 301 bp was seen on agarose gel, whereas the PCR product of M. tuberculosis complex DNA was a 245-bp fragment with these primers. The addition of a small number of M. smegmatis 1008 cells to clinical samples before DNA purification enables the detection of problems which may be due to the loss of DNA in the isolation procedure or to the presence of inhibitors. The presence of inhibitors of the amplification reaction can be confirmed by the addition of M. smegmatis 1008 DNA after the DNA isolation procedure. Furthermore, competition between the different target DNAs of M. smegmatis 1008 DNA and M. tuberculosis complex DNA enables the estimation of the number of IS6110 elements in the clinical sample.
