FIGURE 4.

Colonization of the wild-type and tolB mutant in bladder and kidneys of UTI mice. At 48 h of post infection, bladder, left kidney (kidney-L) and right kidney (kidney-R) were aseptically and separately removed. Each cell number of bacteria isolated from these organs was represented by CFU (colony forming unit). Each data point represents a sample from an individual mouse. Horizontal bars indicate the median values. The tolB mutant was colonized in both bladder and kidneys in significantly lower degree than the wild-type parent (P < 0.01). Asterisks denote significance for values.
