Results obtained in this study showed that EHEC O157 has been isolated and identified from most of the examined milk and dairy products samples except from raw camel’s milk, Ricotta and ice cream samples, as refereeing to positive results confirmed sequencing of by 16S rDNA (Table-1). In our results, the percentage of suspected EHEC growth on TC-SMAC was 25% (27/108), whereas confirmation by sequencing 16S rDNA yielded 10% (11/108). Discrepancies between the isolation rates of bacteria by conventional methods and those by molecular identification (PCR and 16S rDNA sequencing) have been reported earlier .
