Survival profiles of Bp -844 and Bt -UE5 in Mφs and MoDCs. Immature (A and B) and IFN-γ activated (C and D) cells were exposed to Bp-844 and Bt-UE5 at a MOI of 1 and the mean numbers of intracellular bacteria determined up to 16 hr post-infection are shown. The error bars for each data point represent the standard error from the mean. Number in parenthesis indicates the number of donors in each experiment. * indicates a significant difference as analyzed with paired-samples t-test, with P < 0.01.
