rFimA-specific IgG and IgA Ab responses in young adult and aging mice. BALB/c (8- and 48-week-old) mice were nasally immunized as described in Fig. 2 legend. Seven days after the last immunization, the levels of rFimA-specific plasma IgG (a) and IgA (b) Abs were determined by rFimA-specific ELISA. The values shown are the mean ± SE (n = 20). *p < 0.05, when compared with mice group given rFimA alone
