Introduction to helminth
Helminth means worm. Their motile activity is accomplished by wriggling movement. The helminth of medical importance belong to 3 classes: Nematoda, Trematoda and Cestoda.
Geohelminths refer to the helminths which complete their life cycles not requiring the processes of the development in intermediate hosts. They have only one host and a simple life cycle, such as ascarid, hookworm, pinworm and etc.
Biohelminths refer to those that have to undergo the development in intermediate hosts to complete their life cycle , such as filaria, liver fluke, pork tapeworm and so on.
