Anti-adherence effect of cranberry extract consumption on uropathogenic E. coli (UPEC) adherence to cat urinary epithelial Crandell-Rees feline kidney (CRFK) cells. The effect is shown in micrographs of Giemsa-stained preparations in which feline UPEC strain C571 appears adhering to CRFK urinary epithelial cells after growth in urine samples. A – uninfected CRFK cells; B – UPEC adherence to CRFK cells after growth in urine sample U2 collected from cat 2 given the control diet; C – UPEC adherence to CRFK cells after growth in urine sample U2CR0.1 collected from cat 2 given cranberry powder at 0.1% in its diet; D – UPEC adherence to CRFK cells after growth in urine sample U2CR0.3 collected from cat 2 given cranberry powder at 0.3% in its diet
