<p>The present disclosure provides a method and system for the PCR amplification of a target sequence which suppresses non-specific amplification products. The disclosure concerns the use of a primer pair optimized to amplify a nucleic acid of a contaminant in the background of genomic DNA of a first organism. When DNA from a second organism suspected for comprising the contaminant is subjected to the same PCR-based amplification reaction, detection sensitivity and specificity of the contaminant is enhanced when an amount of genomic DNA of the first organism is present in the amplification reaction.</p> |
