Correlations between sporocyst quantity and cercarial output for SmLE (HS) and SmBRE (LS) parasites. a There was a strong correlation between the proportion of sporocysts present in the snail tissue and the quantity of cercariae released by the same snail (Pearson’s r = 0.77, P = 1.058 × 10−12). This correlation was mainly driven by the SmLE (HS) parasite population (Pearson’s r = 0.43, P = 0.022) (b). c There was no significant correlation for the SmBRE (LS) parasite population (Pearson’s r = − 0.17, P = 0.343)
