This study was designed to isolate of Enterohaemoragic E.coli O157:H7 from feces and urine in cattle.

175 samples (80 fecal and 95 urine) were collected to isolate EHEC O157:H7 during the period from March to June 2014 from Al- Hindia slaughter house from local breeding cattle, aged between 1-2 years and over 2 years, and the samples were subjected to culture on specific media Cefixime Tellurit- Sorbitol MacConkey agar at 37 ˚C for 18-24 hrs.

then the isolates were identified by biochemical tests (Indol test, Potassium cyanid test) and seriologically by Latex Kit test.

The results showed that 73(91.25%) out of 80 fecal samples and 39(41%) out of 95 urine samples were E.coli O157:H7 positive, the total of positive isolates were 64%.

That reveals the important role of feces and urine samples to contaminate the environment and disseminate of infection.
