Reduction in the number of cercariae released from infected snails by spirulina feed. A In each column, the dots indicate the number of cercariae released from infected snails that were fed, and the boxes indicate the 25–75% range (one of three experiments is shown). Student’s t test was used to determine the significance of differences in means between two groups. B Each column shows the survival rate of infected snails treated with the feed (mean of three experiments). C In each column, the dots indicate the number of cercariae when infected snails were given feed containing different concentrations of spirulina, and the boxes indicate the 25–75% range. One-way ANOVA was employed, followed by the Tukey test for post hoc analysis of significant differences
