Abstract

We studied the effect of DNA preparation methods of Listeria monocytogenes DNA on PCR sensitivity for L. monocytogenes detection with specific primers. We tested eight lysis protocols for releasing of DNA with detergents, enzymes and/or high temperatures. Considering PCR detection limit in a range from 105 to 106 cfu/ml, rapidity, low cost and preparation simplicity, we chose lysis solution consisting of 0.05 M NaOH and 0.125 % SDS to be used in the optimal procedure for L. monocytogenes DNA preparation.
