Mean haematological parameters from red foxes experimentally infected with Angiostrongylus vasorum and uninfected controls 0–9 weeks post-inoculation (p.i.). Mean counts of peripheral blood eosinophils (a), total white blood cells (WBC) (b) and platelets (c) in foxes during experimental Angiostrongylus vasorum infection. Groups: Juv50 (■), Juv200 (▲), JuvC (●) (controls), Ad50 (□), Ad200 (Δ), and AdC (○) (controls). Calculated reference ranges are indicated by horizontal dashed lines; only upper limit visible for eosinophils. Significant differences between infected and control groups are marked for dose 50 (*) and (^) for dose 200 at P < 0.05. Note: Juv, juvenile foxes; Ad, adult foxes; 50/200, animals inoculated with 50 or 200 infective third-stage larvae, respectively
