Larval (L), nymphal (N) and adult (A) stages of Ixodes ricinus (IR), I. trianguliceps (IT), I. frontalis (IF), I. arboricola (IA) and I. hexagonus (IH) feeding on different vertebrate species were tested for the presence of A. phagocytophilum DNA. The infection rates of ticks from animal species in bold are significantly higher than those of ticks from the vegetation (Table 1). The 95%-confidence intervals of these infection rates, which were calculated using Fisher's exact test, are between brackets. Data from sand lizards are derived from a previous study [32].
