From: Stress significantly increases mortality following a secondary bacterial respiratory infection
Stress alters the antiviral response but not the acute-phase response responses. (A) IFN-γ levels in nasal secretions on day 3 post-BHV-1 infection were compared between weaned and maternal separation (WMS) and pre-adapted (PA) calves (n = 10/group) and data was also sorted for calves that died (Dead; n = 12) or survived (Day 0; n = 8) following M. haemolytica infection. Data presented are values for individual animals and horizontal bars represent median values for each group. *p < 0.05. (B) Serum haptoglobin levels determined by capture ELISA were compared between WMS and PA calves (n = 10/group) and data was also sorted for calves that died (Dead; n = 12) or survived (Day 0; n = 8) following M. haemolytica infection. Data presented are values for individual animals and horizontal bars represent median values for each group. **p < 0.01.
