Immune response to sympatric and allopatric parasites in a snail-trematode interaction.

When the controls (no exposure) were deleted and the data set was analyzed as a three-factor experiment, there was only a marginally significant effect of parasite source on hemocyte count ( F = 3.69, d.f. = 1, 40, P = 0.06); no other effects or interactions were significant (Fig. 3 , Table 3 ).

In contrast, however, the interaction effect was highly significant for infection success; but there were no significant main effects for either host source or parasite source (Fig. 1 , Table 1 ).
