NR4A1 and infection: There was no significant difference in the overall level of acute UPEC bacteriuria at 24 hours post infection (hpi) during the initial infection between the mouse strains (Figure 4A), although the proportion of mice with low titers (<104 CFU/mL) was significantly greater in Nur77-/- compared to WT mice (0% WT, 14% Nur77-/-; Fisher’s exact P < 0.05).
