Table 2 Presence of rickettsiae in Dutch wildlife.

From: Ixodes ricinus ticks are reservoir hosts for Rickettsia helvetica and potentially carry flea-borne Rickettsia species

Animal (n) R. helvetica(n) R. conorii(n) R. SP. IRS(n)
Mouse (146) 29% (43) 1.4% (2) 14% (20)
Roe deer (21) 19% (4) 0 0
Wild boar (29) 6.9% (2) 0 0
Red deer (10) 0 0 0
  1. Wildlife from different geographical locations (see Figure 1) was tested for the presence of Rickettsiae. Whole blood samples of animals (number) were collected between 2000 and 2002, and the infection rate with R. helvetica and R. conorii is expressed as a percentage.
