FIG. 4.

Effect of SXT on bacterial persistence in the bladder. C57BL/6 mice were infected with UTI89 SR and treated with SXT for 3 days (black circles) or 10 days (red circles) or were left untreated (white circles). Bladders were harvested at days 3 and 28 after infection, and serial dilutions of the bladder homogenates were titered to determine the level of culturable UTI89 SR remaining in the bladder. The black bars indicate the median values.
