Introduction to Helminths. The term “Helminths” mean “worms” in parasitology. It refers to the parasitic worms, those comprises two large phyla: Phylum Platyhelminths (flat worms) and Phylum Nemathelminths or Nematoda (true round worms), and two smaller ones: Phylum Nematomorpha (hair snakes) and Phylum Acanthocephala (thorny-headed worms), in addition to one class group from phylum Annelida, the class Hirudinea (Leeches)..

It is commonly known as thread worms. They are unsegmented, typically elongated and cylindrical with a fundamental bilateral symmetry. They have a complete digestive tract, dioecious with few exceptions (the nematodes are usually bisexual, but in a few instances the female may be parthenogenetic).. Gh. . . Fajir. . Helminthic.
