This study assessed the effects of a commensal, Chaetogaster limnaei limnaei, and a parasitic trematode, Schistosoma mansoni, on infection patterns and life-history responses in the aquatic snail Biomphalaria glabrata. Prevalence of infection was significantly higher in snails that were devoid of C. limnaei limnaei relative to those that were colonized by the commensal, indicating that the oligochaete may protect the host from trematode infection. This finding appeared to be the direct result of the commensal as opposed to indirect stimulation of the immune system, as hemocyte numbers did not differ between C. limnaei limnaei–colonized and noncolonized snails. Snail growth and reproduction were affected by the presence of C. limnaei limnaei and exposure to S. mansoni. Two-way ANOVA revealed a significant effect of both C. limnaei limnaei presence and trematode exposure on B. glabrata growth over the 5-wk study with C. limnaei limnaei–colonized and parasite-infected snails demonstrating the greatest growth. Snails exposed, but uninfected, by S. mansoni demonstrated the lowest growth regardless of commensal colonization. Chaetogaster limnaei limnaei colonization had no effect on egg production, but S. mansoni–infected snails produced significantly more eggs than individuals from other treatment groups. Survival remained over 85% in all treatment groups. The ecological implications of these results are discussed.
