Nematoda

Introduction: Nematoda

Description of Nematoda

Nematoda: The roundworms, a large phylum that includes many of the helminths parasitic in humans and a far greater number of plant-parasitic and free-living soil and aquatic nonparasitic species. For practical purposes, the parasitic nematodes may be placed in two groups, based on their adult habitat in the human body: 1) the intestinal roundworms (e.g., the genera Ascaris, Trichuris, Ancylostoma, Necator, Strongyloides, Enterobius, and Trichinella); and 2) the filarial roundworms of the blood, lymphatic tissues, and viscera (e.g., the genera Wuchereria, Mansonella, Loa, Onchocerca, and Dracunculus).
