Figure 4. Syringe lysis in excystation media may slightly improve sporozoite yield.

The box and whisker plots show the min to max number of sporozoites excysted prior to and after syringe lysis in excystation media for H. hammondi and T. gondii. Each point represents the number of sporozoites excysted for a given experiment. This data shows a general, but not significant, increase in the number of sporozoites excysted after syringe lysis. (Two-way ANOVA, Sidak’s multiple comparison test, H. hammondi P=0.47, T. gondii P=0.88).
