Exopolysaccharide vaccine extracted from C.freundii induce immunity against infectional pathogens


Eleven isolates of Citrobacter. freundii were isolated from100 stool and urine specimens taken from diarrhea and recurrent –urinary tract infections (UTI) patients attended to AL-Sadar Hospital. specimens were cultured on specific media, then bacterial isolates were identified depending on morphological, biochemical and VITK-2. The results showed that the C. freundii comprise 11 / 78 (14.1 %) of total of positive bacterial growth on macConky agar from which 10.2 % isolated from patients suffering from diarrhea and 3.8 % isolated from UTIs .
