NK cell-like function of PBMCs after IV administration of CNV-NT. Mean ± SD of NK cell-like function of PBMCs at time 0 (pretreatment), and then 7, 14, and 28 days post IV CNV-NT spore administration when evaluated in ratios of PBMC:CTAC cells of 1:1, 10:1, 25:1 and 50:1. There was a significant difference between day 7 (P < 0.012 for all ratios) (a), day 14 (P < 0.005 for all ratios) (b) and day 28 (P < 0.048 for all ratios) (c) and baseline.
