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.

The purpose of this study was to investigate bacterial contamination and heavy metal concentrations in 80 samples of raw milk (cow: 40 and buffalo: 40) gathered from local markets in Baghdad, Iraq. The culture results were classified into ten categories: E. coli was 100% in each cows and buffaloes, Enterobacter Spp 23.75% (25% cow, 22.5% buffalo), Pseudomonas Spp 13.75% (15% cow,12.5% buffalo), Klebsiella Spp 15% (17.5% cow, 12.5% buffalo), Staphylococcus aureus 12.5% (15% cow, 10% buffalo), Staph. epidermidis 5% (for each cow and buffalo), Proteus spp. 10% (12.5% cows, 7.5% buffaloes), E. coli O157 15% (25% cow, 5% buffalo), Yersinia enterocolitica 3.75% (5% cow, 2.5% buffalo) and Salmonella 13.75% (25% cow 2.5% buffalo). The averages of heavy metals concentrations in cow milk samples were 0.62±0.25, 0.25±0.22, 0.31±0.20 and 21±2 mg/kg and in buffalo milk samples were 0.60±0.3, 0.33±0.15, 0.27±0.11 and 18±2.5 mg/kg for Lead (Pb), Cadmium (Cd), Copper (Cu) and Nickel (Ni) respectively. The high concentrations of pathogenic bacteria and metals found in the milk products is a sign of inadequate hygiene and sanitation during milking and post-milking operations, as well as excessive levels of heavy metal pollution in the environment which will affect meat and milk produced by these animals.

Urinary Schistosomiasis is one of important diseases that cause irritation and damage of urinary tract and other systems and tissues and can not be expected by doctors when diagnosing urinary tract diseases.The current study is conducted to investigate the prevalence of schistosomiasisin Baghdad / Al-Rusafa. 191urine samples were collected fromresidents ofsome areas of Al-Rusafain Baghdad governarate (Almashtal, Albaladyat, Alameen, Baghdad aljadida and Alnahrawan) for the period from March until the end of September 2010.The samples were examined by the precipitation and examination of micro hematuria by reagent strips. The total infection percentage was 9.42% (18/191) and was significantly higher in males compared tofemales12.64% (11/87), 6.73% (7/104) respectivly, and in ages
