Table 2 Post-mortem worm counts and worm recovery (%) in red foxes (juveniles and adults) infected with 50 or 200 infective third-stage larvae of Angiostrongylus vasorum, including uninfected controls. Worm isolation comprised three subsequent procedures (reverse perfusion, dissection and baermanization of the lungs). Statistical analysis (ANOVA) included infected groups only
