Popis: In diagnostic and research bacteriology settings with budget and staff restrictions, fast and cost-effective genome extraction methods are desirable. If not inactivated properly, cellular and/or environmental DNA nucleases will degrade genomic material during the extraction stage, and therefore might give rise to incorrect results in PCR experiments. When crude cell extracts, proteinase K–treated templates and purified DNAs prepared by phenol-chloroform-isoamylalcohol method as well as a commercial extraction kit were subjected to the Salmonella enterica Enteritidis specific STM2 PCR, with exception of crude cell extract, PCR products from all other three methods saved their integrity for 28 days post-generation. This work aimed to find out whether improvement to boiling method can guaranty stability of PCR products. As results showed, treatment of crude cell extracts from S. Enteritidis with proteinase K offers an inexpensive, fast and effective DNA extraction method suitable for high-throughput laboratories.
