Snail survival and cercariae production in experimental condition: constant temperature and natural photoperiod

Radix sp.	Temperature (°C)	Survival avg. (days) (± SE)	Number of emerged cercariae/snail (± SE)
Non–infected	19	23 (±1)	–
With T. ocellata	19	12 (±1)*	1657 (±54)a
With D. pseudospathaceum	19	11 (±1)*	990 (±110)b
With T. clavata	19	8 (±1)*	503 (±35)c

Different letters indicate statistically significant difference between compared values (a/b, p < 0.01, b/c, p < 0.01, a/c, p < 0.001)

*Statistically different from non-infected ones (Tukey test p < 0.001)
