Conversely, mice harboring AIBC C. rodentium showed significantly lower levels of expression than Acute group mice of all the tested genes, except Nos2 (P = 0.0513) (Fig. 2D to G), although with a spread of expression levels that was broader than that of UI+Kan mice (Fig. 2D to G), which likely reflects the gradual resolution of inflammation following an acute infection. Here, NOS2 is linked to infection.
