'Water obtained from alternative sources should be brought to a rolling and boiled for at least one minute to kill any cercariae.
All snails were inspected for shedding cercariae, and although cercariae from snails at site 5 were seen, identification by microscopy (x100) was unsuccessful.
After this step, five snails were placed in clear glass vials (30 mL capacity) with 25 mL of dechlorinated water, that is, 5 mL per snail, where they were exposed to light (100 W lamps), at one distance of 30 cm for 1 h to stimulate the release of cercariae (Smithers & Terry 1965).
The presence of partenites (rediae) and larvae (cercariae) in the body of mollusks was determined using a microscope "XS-6320 (MICROmed, Poltava, Ukraine)".
Once within the snail, successful miracidia transform into a sporocyst, a sac-like structure that generates genetically identical cercariae (another small, swimming larvae--see Figure 1), which emerge periodically from infected snails to seek out the next host in the parasite's life cycle.
The miracidium must then pass through an intermediate snail host, before the next larval stage of parasite; the furcocercous cercariae emerges that can infect a new mammalian host by directly penetrating the skin (Soulsby, 1982, Bhatia et al., 2010).
