Organ and experiment had a significant effect on the tissue spirochete load of B. afzelii in the bank voles. The spirochete loads were standardized per mg of DNA and then log10-transformed. For the Finnish bank voles, the tissue spirochete loads were higher compared to the Swiss bank voles. The rank order of the organ spirochete loads (from lowest to highest) depended on the experiment: bladder, ear, ventral skin, ankle joint for the Swiss bank voles and bladder, ventral skin, ankle joint, ear for the Finnish bank voles. Shown are the medians (black line), the 25th and 75th percentiles (edges of the box), the minimum and maximum values (whiskers), and the outliers (circles).
