Role of X-ray on theTreatment of UTI Induced By Escherichia coli

This study was conducted to investigate the effect of differentdoses of x-ray on the treatment of experimentally UTI induced by E.coli isolate in rabbits which used as an animal model. E.coli isolate was obtained from patient suffering from UTI in AL-Krama hospital- Baghdad city,the isolate was diagnosis by cultural,morphological, biochemical tests and confirmed by using API 20 E system. Results of treatment with X-ray showed no growth of E.coli from all tested organs kidney,urinary bladder ,spleen,liver,heart and lung in negative control (group 1) which were not infected with E.coliwhile other groups showed various value of bacterial isolation according to the doses of x-ray. On the other hand group 6 which were treated with high doses of x-ray showed negative results for the isolation of E.coli from all the tested organs. The results of group2(infected without treatment ) showed the ability of E.colito infectkidney and bladder with the appearance of acute clinical signs as compared with the negative control. The results of histopathological changes showed the role of x-ray in decreasing the pathological signs in tissue and giving negative results for E.coli isolation in comparison with the positive control(group 2) which showed acute histopathological changes.
