  1. Ticks were collected by blanket dragging on various locations in The Netherlands and Belgium (three locations). The 95%-confidence intervals, which were calculated using Fisher's exact test, are between brackets. The five locations with infection rates significantly lower than 3% are indicated in bold. The four locations with infection rates significantly higher than 3% are indicated in cursive bold.
