Other articles where Helminth is discussed: anthelmintic: Helminths can be divided into three groups: cestodes, or tapeworms; nematodes, or roundworms; and trematodes, or flukes. The helminths differ from other infectious organisms in that they have a complex body structure. They are multicellular and have partial or complete organ.Helminths are characterized by the presence of attachment organs which include suckers, hooks, lips, teeth, and dentary plates. Key Terms. parasitic worm: Parasitic worms are referred to helminths as they live and feed on living hosts. Helminths receive both nourishment and protection by disrupting the hosts ability to absorb nutrients.Helminths develop through egg, larval (juvenile), and adult stages. Table 86-1 gives the names applied to various larval helminths. Knowledge of the different stages in relation to their growth and development is the basis for understanding the epidemiology and pathogenesis of helminth diseases, as well as for the diagnosis and treatment of patients harboring these parasites.

Ascaris and hookworm eggs become infective as they mature.This chapter deals with the structure and development of the three major groups of helminths. Helminths develop through egg, larval (juvenile), and adult stages. Table 86-1 gives the names applied to various larval helminths. Knowledge of the different stages in relation to their growth and development is the basis for understanding.Helminths are parasitic worms that feed on a living host to gain nourishment and protection, while causing poor nutrient absorption, weakness and disease in the host.
