Fig. 4From: Acute phase proteins as local biomarkers of respiratory infection in calvesProtein fractions in blood sera of calves before and after inoculation with Chlamydia psittaci. 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 post inoculation; grey: animals prior to inoculation with Chlamydia (C.) psittaci; white: animals after inoculation with C. psittaci (n = 13); #: 0.05 ≤ P < 0.1; *: 0.01 ≤ P < 0.05; ** 0.001 ≤ P < 0.01Back to article page
