Comparison of three rapid and easy bacterial DNA extraction methods for use with quantitative real-time PCR.

ABSTRACT: The development of fast and easy on-site molecular detection and quantification methods for hazardous microbes on solid surfaces is desirable for several applications where specialised laboratory facilities are absent. The quantification of bacterial contamination necessitates the assessment of the efficiency of the used methodology as a whole, including the preceding steps of sampling and sample processing. We used quantitative real-time polymerase chain reaction (qrtPCR) for Escherichia coli and Staphylococcus aureus to measure the recovery of DNA from defined numbers of bacterial cells that were subjected to three different DNA extraction methods: the QIAamp DNA Mini Kit, Reischl et al.'s method and FTA Elute. FTA Elute significantly showed the highest median DNA extraction efficiency o
