LPT results, per C. burnetii phase 1 and phase 2 stimulus, related to parturition. Lymphocyte proliferation test results of the control goats and Coxiella-inoculated goats. Data are expressed as average results of the group in fold induction compared to medium-incubated cells. The X-axis indicates weeks related to parturition (time point 0). A: results after stimulation with C. burnetii Phase 1 (▲: C. burnetii-inoculated goats; −: control goats). B: results after stimulation with C. burnetii Phase 2 antigen (●: C. burnetii-inoculated goats; −: control goats); *: P ≤ 0.05; **: P ≤ 0.01.
