Relative lipopolysaccharide (LPS)-reactive antibody levels (A) and relative keyhole limpet hemocyanin (KLH)-reactive antibody levels (B) from day 5 to day 36. A, LPS-reactive antibody levels for offspring of female zebra finches exposed to LPS and offspring of females exposed to KLH or phosphate-buffered saline (control). B, KLH-reactive antibody levels for offspring of female zebra finches exposed to KLH and offspring of females exposed to LPS or control. Birds received a primary injection of LPS, KLH, or control on day 5 and a secondary injection on day 28. In A, data are from birds whose mothers were exposed to LPS and/or who were exposed to LPS themselves, whereas in B, data are from birds whose mothers were exposed to KLH and/or who were exposed to KLH themselves. Error bars represent mean ± SE, and an asterisk denotes a significant (P < 0.05) difference between groups for that day via post hoc t-tests.
