It was achieved by inoculation 106 CFU from three E. coli O157:H7 strains; ATCC 35150 (Strain 1), (Strain 2) and (Strain 3) isolated from River Nile and El-Rahawy Drain, respectively into two portion; sterile and non-sterile portion of ground, River Nile and El- Rahawy Drain water. All strains possesses five virulence genes (stx1 (Shiga toxin 1), stx2 (Shiga toxin 2), eae (intimin), rfbE (O157 antigen), and fliC (flagellar antigen)). It was found that, the prolonged survival E. coli O157:H7 was observed up till 98 days in sterilized wastewater followed by survival for 84 days in both sterilized ground and River Nile water. E. coli O157:H7 survived in all sterilized tested water types longer than non sterilized water. It was found that the E. coli O157:H7 isolated from wastewater sample had the longest survival time (98 days) in sterilized wastewater compared to the other strain (reference strain and isolate of River Nile).</div>
