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 are parasitic worms that cause a wide variety of infectious diseases, some of which involve the musculoskeletal system. Helminths may be classified into nematodes or roundworms.

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.A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Protozoa Protozoa are microscopic, one-celled organisms.

Helminths -- The three distinct phyla of helminths found as parasites in fin fish Pollock and other coastal fish of Norway may be heavily parasitized by larvae.An infection by a helminth is known as helminthiasis, helminth infection or intestinal worm infection. There is a naming convention which applies to all helminths: the ending -asis (or in veterinary science: -osis ) is added at the end of the name of the worm to denote the infection with that particular.

Introduction. Helminths (the word is derived from the Greek meaning “worms”; ref. 1) have plagued humans since before the era of our earliest recorded history.The eggs of intestinal helminths can be found in the mummified feces of humans dating back thousands of years (2–4), and we can recognize many of the characteristic clinical features of helminth infections from the ancient writings.The future of helminth taxonomy will be heavily influenced by DNA studies. The DNA database for helminth species is rapidly expanding and allows specimens collected today to be identified in the future. Therefore, it is important to preserve (in formalin-free fixative) a subset of specimens in ethanol for DNA extraction.

The clinically relevant groups are separated according to their general external shape and the host organ they inhabit.
