Effect of challenge with lipopolysaccharide (LPS) on corticosterone (CORT) concentrations one hour after primary challenge (A), haptoglobin concentrations 12 hours after secondary challenge (B), and anti-LPS antibody titers 8 days after secondary challenge (C). Birds challenged with LPS had significantly higher CORT concentrations and elevated anti-LPS antibody titers relative to control birds, but LPS challenge did not significantly impact haptoglobin concentrations. Diamonds represent birds that received CORT treatment, and circles are those that did not receive CORT.
