Bovine serum albumin (BSA) in calves. (a) BSA in blood sera of calves before and after inoculation with Chlamydia (C.) psittaci. Post inoculation blood 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). (b) BSA in BALF supernatant of healthy and C. psittaci-infected calves. BALF values of infected animals were compared to the first sample from healthy controls, since at that time point the age difference between the animals was lowest (Mann–Whitney-U test with Holm adjustment). 1, 2, 3: first, second, and third sample from healthy controls; light blue: healthy control animals (n = 6); white: animals after inoculation with C. psittaci (n = 13). #: 0.05 ≤ P < 0.1; *: 0.01 ≤ P < 0.05
