Open field activity following increasing doses of E. coli in male and female mice.

Notes: Mean total distance moved of male (A) and female (B) FVB mice in the open field 3 hours after a single ip injection of different concentrations of E. coli. Bars represent group means ± SEM. Different letters above each bar indicate significant differences among groups (P < 0.05), otherwise group means are not significantly different from each other.

Abbreviations: cfu, colony forming unit; E. coli, Escherichia coli; ip, intraperitoneal; PBS, phosphate buffered saline; SEM, standard error of the mean.
