Dynamics of humoral responses in mice after orally infected with <i>T</i>. <i>gondii</i> cysts.

<p>Detection of <i>T</i>. <i>gondii</i>-specific IgG (A) and IgM (B) in the serum of BALB/c mice (n = 3) infected with four cysts at 1, 3, 5, 7, 9, 11, 13, 15, 22, 30, 45 dpi with ELISA. Results are expressed as mean of the OD 450/630 ± S.D. Inverted black triangle <i>p</i><0.01 (different dpi compared with 1 dpi for IgG), * <i>p</i><0.05, ** <i>p</i><0.01(different dpi compared with 1 dpi for IgM).
