  2. Swimmer’s Itch (sum up in your notes) • Swimmer's itch is an itchy rash caused by certain parasites that normally live in freshwater snails and sometimes on waterfowl (duck). • On warm, sunny days, these parasites can be released into mainly fresh water or occasionally salt water. During your swim, the parasites might burrow into your skin, where they cause the swimmer's itch rash. But humans aren't suitable hosts for them, so the parasites soon die while still in your skin. • Although uncomfortable, swimmer's itch is usually short-lived. The rash of swimmer's itch, also called cercarial dermatitis, typically clears up on its own within a few days. In the meantime, you can control itching with over-the-counter or prescription medications.

  3. Swimmer’s Itch Animation Every lake in Michigan can have swimmer’s itch parasite 1/80 of an inch long and clear

  4. 2 ways to control swimmer’s itch 1. biological – dog tapeworm shots to each duck 2. chemical – copper sulfate poured into lakes; kills snails/clams (not good)

  5. Swimmer’s Itch Microscope Lab • The students will crush snails found in Muskegon Lake to see if we can find the swimmer’s itch parasite. • In notebook, draw sketches if you find miracidiacercariae
