Invasion of the uroepithelial cells by UPEC. (A) Invasion percentage of bladder 5637 epithelial cells by J96 grown in either pH 7.0 with no NaCl medium (J96-1) or pH 5.5 with 400 mM NaCl medium (J96-P). * p < 0.05 vs. J96-P. (B) Invasion percentage of renal 786-O epithelial cells by either J96-1 or J96-P. * p < 0.05 vs. J96-1. (C) Invasion percentage of 5637 and 786-O epithelial cells by non-fimbriated E. coli 83972 and P-fimbriated 83972 (83972-P). * p < 0.05 vs. 5637 cells infected by 83972-P.
