Distribution of shared glycotopes expressed on hemocytes from the susceptible (NMRI) and resistant (BS-90) strains of Biomphalaria glabrata. Treatment of hemocytes with larval transformation products (LTPs) significantly modulates expression of shared glycans as determined by reactivity to specific anti-glycan monoclonal antibodies. Prevalence data represent the mean ± S.D. of 3–6 independent replicates. Significance levels were set at α < 0.05 (2-factor ANOVA; see Results)
