Relationships between clinical signs and markers of acute phase reaction assessed in blood (a) or BALF (b) in calves with an acute respiratory infection induced by Chlamydia psittaci. Models of multiple regressions (n = 39). a Dependent variable: General Clinical Score (z-axis). Independent variables: concentrations of bovine serum albumin (BSA; x-axis) and LBP (y-axis) in blood serum. R2 = 35.4 %. P-Value of the model = 0.0004. b Dependent variable: Respiratory Score (z-axis). Independent variables: concentrations of Lipopolysaccharide Binding Protein (LBP; x-axis) and Haptoglobin (Hp; y-axis) in broncho-alveolar lavage fluid (BALF). R2 = 55.3 %. P-Value of the model = 0.0000
