^aFive mice per immunization group were bled 1 day following the final dose.

^bBlood samples were processed to determine white blood cells (WBC), monocytes (MON), lymphocytes (LYM), neutrophils (NEU) and eosinophils (EOS). All the counts are given in 10² cells/µl.

Data are expressed as the mean ± SD of individual measurements. Differences among groups were not observed after ANOVA and Bonferroni's Multiple Comparison test. The results in this table represent one of two independent experiments.

Sp: B. subtilis WW02 spores; HkSp: Heat-killed B. subtilis WW02 spores.
