چکیده مقاله:

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.

Salmonella enterica Serovar Enteritidis, Japan

To the Editor: Nontyphoidal sal-monellae are the important causative agents of foodborne diseases in Japan and other industrialized countries. Salmonella enterica serovar Enter-itidis has risen to the leading cause of infection among Salmonella spp. since 1989 (1). Emergence of drug-resistant S. Enteritidis has been rarely reported while S. Typhimurium, another serovar of major public health co...

An Allelotyping PCR for Identifying Salmonella enterica serovars Enteritidis, Hadar, Heidelberg, and Typhimurium

Current commercial PCRs tests for identifying Salmonella target genes unique to this genus. However, there are two species, six subspecies, and over 2,500 different Salmonella serovars, and not all are equal in their significance to public health. For example, finding S. enterica subspecies IIIa Arizona on a table egg layer farm is insignificant compared to the isolation of S. enterica subspeci...

Occurrence of multidrug-resistant Salmonella enterica serovar Enteritidis isolates from poultry in Iran

Salmonella enterica is recognized as one of the major food-borne pathogens with more than 2,500 serotypesworldwide. The present study addresses antimicrobial resistance of Salmonella enterica serovar Enteritidisisolates in Iran. A collection of 151 Salmonella spp. isolates collected from poultry were serotyped toidentify Salmonella Enteritidis. Sixty-one Salmonella Enteritidis were subsequently...
