Coxiella burnetii DNA in ticks during and after feeding. Each red dot represents one tick, which was used for DNA extraction after feeding on blood inoculated with 106 GE/ml of C. burnetii Nine Mile phase II. The means are indicated by a horizontal line. During the first two time points, the ticks were still feeding. Ticks were kept separated from each other after detaching from the membrane. Mock-infected ticks (one per time point, not shown) had no Cq-value. The data derive from two independent experiments and were normalized for the two Ixodes ricinus housekeeping genes actin and elongation factor 2
