Specific IgA levels in fecal pellets after oral immunization. The mice (10 every group) received three consecutive immunization, three times at 2-week intervals. The control group of mice received the same dose of pPG612.1. Fecal pellets were collected 1, 2, and 7 days after every immunization. Both of the groups immuned with pPG612.1-VP4 or pPG612.1-VP4-LTB produced specific IgA. Statistically significant difference (** P < 0.01) was observed in fecal pellets of mice administered with recombinant strains after one day. The levels of IgA in fecal pellets induced by pPG612.1-VP4 appeared lower than those induced by pPG612.1-VP4-LTB (*P < 0.05,**P < 0.01). Results are the IgA titers ± standard errors of the means in each group.
