Cercariae may penetrate the skin or are ingested by the aquatic bird/animal, develop into an adult worm, and the cycle starts again. The miracidium enters the snail, elongates into a sporocyst, then matures into a cercaria which burrows out of the snail into the water. An egg hatches in the water to become a free-swimming miracidium in search of a specific snail species. The adult worm lives in a bird/animal, and the eggs are excreted via the intestines in the faeces.
Schistosomes are parasitic flatworms with a lifecycle that involves aquatic birds (eg, ducks, geese, gulls, swans) or mammals (eg, beavers, muskrats), specific species of aquatic snails, and warm fresh or salt water. Swimmer’s itch is a disease of aquatic birds and humans are accidentally affected. However, it is only after repeated exposure to cercariae that the allergy develops and a rash eventuates. Young children are particularly susceptible as they tend to remain in shallow warm water where the snails are found in the highest numbers. Swimmer’s itch can affect anyone swimming in waters with infested snails.
