In this study, three bacterial DNA extraction procedures were compared prior to real-time PCR. Healthy pear leaves and twigs were crushed in antioxidant maceration buffer and spiked with Erwinia amylovora to final concentrations from 2.1 x 10(6) to 2.1 x 10(1) cells ml(-1). Bacterial DNA was extracted from aliquots of spiked crude extracts using (i) isopropanol, (ii) REDExtract-N-Amp (TM) Plant PCR kit, and (iii) Taylor's modified DNA purification procedure. The ams region of the chromosomal DNA was selected as target for the real-time PCR. In this study, the REDExtract-N-Amp (TM) and Taylor's modified DNA extraction procedure were most successful in removing PCR inhibitors, leading to detection of 2.1x10(2) E. amylovora CFU/ml. At this concentration, pathogen can be efficiently detected in less than 5 h in spite of inhibitors and plant DNA reducing sensitivity of the reaction. These two methods increased amplification efficiency in real-time PCR compared to a simple isopropanol DNA ex...traction procedure from plant tissues, where the lowest detected concentration was 2.1 x 10(4) CFU/ml. In our research, real-time PCR has proven to be very sensitive method for detection of E. amylovora in plant material. It was 100 times more sensitive compared to other conventional PCR procedures.
