Effect of S. solidus growth on susceptibility to D. pseudospathaceum. Sticklebacks with either high resistance (HR) or low resistance (LR) were experimentally infected with single S. solidus larvae. Parasite indices (parasite weight corrected for host weight) and susceptibility to the eye fluke Diplostomum pseudospathaceum (number of metacercariae in the eye lenses 1 day after exposure to 100 cercariae) were determined in week 3, 6, and 9 post S. solidus infection.
