In total 5392 snails were collected (Table 2) and 13.8% of snails were infected. Xiphidio cercariae and parapleurolophocercous cercariae were observed in each pond, while the non-FZT Transversotrema sp. was found in 2 ponds. Three snails shed other types of cercariae (2 echinostome, 1 monostome), which wereexcluded from further study. After shedding and crushing, the prevalence of both parapleurolophocercous and xiphidio positive snails was 6.6%, of Transversotrema 0.6%. No mixed infections were found, each snail was infected with a single type of parasite. Crushing increased the observed prevalence of shedding, varying from no extra positive snails in one pond, to an increase of 4.7% in another pond.
