Table 1 Live weights and ante mortem parasitological data of red foxes (juveniles and adults) infected with 50 or 200 infective third-stage larvae of Angiostrongylus vasorum, including uninfected controls

From: The effect of host age and inoculation dose on infection dynamics of Angiostrongylus vasorum in red foxes (Vulpes vulpes)

Group n Mean ± SD live weight 21 dpi (kg) Mean accumulated larval counts 41–63 dpi (range) (L1/g)* Prepatent period (range of group) (days)
Juv50 7 5.2 ± 0.9a 62 (13–183)a,b 41–48
Juv200 7 5.3 ± 0.3a 150 (35–432)b 41–48
Ad50 7 6.2 ± 0.4a 53 (2–156)a,b 48–55
Ad200 7 6.1 ± 0.7a 4 (0–16)a 48–57#
JuvC 3 5.0 ± 0.2a
AdC 3 5.7 ± 0.2a
  1. Numbers in columns with different superscripts are significantly different
  2. Abbreviations: dpi days post-inoculation, SD standard deviation
  3. *Statistical analysis by ANOVA on larval counts (r 2 = 0.38): Age: F (1,23)= 8.39, P = 0.0081; Dose: F (1,23)= 0.63, P < 0.44; Age*dose: F (1,23)= 5.94, P = 0.023; Groups were significantly different at P < 0.05 by Bonferroni post-hoc tests
  4. #Two red foxes harbouring 2 and 23 worms did not reach patency
