- Ticks from different geographical locations in The Netherlands were tested for the presence of R. helvetica. Ticks (larvae, nymphs and adults) were collected from different area types, in different years, and the infection rate with R. helvetica is expressed as a percentage. As the infection rates between the different tick stages were not significantly different within each location, the overall infection rate is presented.
