FIG. 6.

L. monocytogenes growth in organs of animals treated with a selective iNOS inhibitor, L-NIL. (A) L. monocytogenes score at day 2 as determined in L-NIL-treated (open triangles) or mock-treated animals (closed triangles). (B) CFU in spleen, liver, and cerebellum tissues at day 2 after treatment with L-NIL (hatched dots) or mock treatment (open dots). The graph accounts for 15 animals per group, infected at different days. The difference between the control group and the L-NIL-treated group is significant (P < 0.01) for the cerebellum. The dotted line indicates the threshold of detection. Horizontal bars indicate the medians in each panel.
