Inactivated Francisella tularensis (iFt)-Mueller Hinton Broth (MHB) induces superior resistance to Ft LVS-induced systemic tissue damage compared to that of iFt-Brain-Heart Infusion (BHI): mice were immunized on days 0 and 21 with phosphate-buffered saline (white bars), iFt-MHB (gray bars), or iFt-BHI (black bars) and challenged with Ft LVS grown in MHB. Lactate dehydrogenase activity was quantified in serum drawn on indicated days postchallenge. Prechallenge sera were drawn 11 days after boost. Each bar represents mean ± SE (error bar) of two independent experiments with a total of eight mice per group. *p < 0.05.
