The role of worm parasitism in snail mating. Introduction: Researcher Curt Lively and his colleagues conducted an experiment in which the collected feces of ducks which are considered as a major source of bacteria and egg eggs of parasitic worms. They treated the feces in following ways: 1. Heat sterilized the feces which killed both bacteria as well as worm egg. 2. Heat sterilized the feces and replaced the bacteria. 3. Using bleach to kill bacteria and leaving the worm eggs as such. 4. No treatment They then added the fecal samples to aquaria in which parasite free mud snail was present.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
