[Mycobacterium szulgai as positive control helps to detect contaminations in the detection of Mycobacterium tuberculosis-complex in formalin fixed, paraffin embedded tissues by 16SrDNA PCR]. / Mycobacterium szulgai als Posititivkontrolle zur Detektion von Kontaminationen beim Nachweis des Mycobacterium tuberculosis-Komplexes durch eine spezifische 16S-rDNA-PCR an FFPE-Material.

ABSTRACT

The detection of Mycobacterium tuberculosis complex DNA by PCR using formalin-fixed paraffin-embedded material has become an integral part of molecular-pathological diagnostics. We describe an approach that enables the detection of contamination by using Mycobacterium szulgai as a positive control, contributing to the reduction of false-positive results.
