AbstractThe main goal of current study is an investigation of detection and expression of hemolysin toxin in E.coli isolates in clinical veterinary infection cases included Mastitis milk, Abortion samples and diarrhea samples from cattle in Al-Diwaniyah city by using real time-polymerase chain reaction technique. Total samples that used in this study are (24) isolates, included (9) isolates from mastitis cases, (5) isolates from abortion cases, and (10) isolates have taken from Diarrhea cases in cattle. The total prevalence of hemolysin in E.coli isolates is 18/24 (75%), where the percentage of occurrence of hemolysin production E.coli isolates by using real-time PCR was 7/9 (77%), 5/5 (100%), and 6/10 (60%) in Mastitis milk, Abortion and Diarrhea cases in cattle respectively. In concluding, production of hemolysin toxin by E.coli isolates have contrast activity depend on the type of sample; the study found the abortion isolates have high gene expression followed by diarrhea isolates, then milk isolates.
