Kinetics of respiratory score and lipopolysaccharide-binding protein (LBP) in blood serum of calves. (a) Respiratory score and (b) concentration of LBP in blood serum of calves before and after inoculation with Chlamydia (C.) psittaci. Blue bars represent time-points of broncho-alveolar lavage and corresponding blood sampling. Blue panel with solid line: exact time point, blue panel with dashed line: blood collection one day after broncho-alveolar lavage. Post inoculation values were compared to the value 1 h before inoculation (−1 h) with the Wilcoxon signed rank test with Holm adjustment. -7 d: 7 days before inoculation; −4 d: 4 days before inoculation; dpi: days past inoculation; grey: animals prior to inoculation with C. psittaci; white: animals after inoculation with C. psittaci (n = 13). The 13 calves served as untreated controls in two previous treatment studies where the general clinical scores and concentrations of LBP in blood sera have been published separately [31, 34]
