Human parasites include various protozoa and worms. Human parasites are divided into endoparasites, which cause infection inside the body, and ectoparasites, which cause infection superficially within the skin. The cysts and eggs of endoparasites may be found in feces, which aids in the detection of the parasite in the human host while also ...
Cestoda. Cestoda is a class of parasitic worms in the flatworm phylum (Platyhelminthes). Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbon-like worms as adults, known as tapeworms. Their bodies consist of many similar units known as proglottids—essentially packages of eggs which are regularly shed ...
Trematoda is a class of flatworms known as flukes or trematodes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate.
Nematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, [1][2][3] or Gordian worms) are a phylum of parasitoid animals superficially similar to nematode worms in morphology, hence the name. Most species range in size from 50 to 100 millimetres (2.0 to 3.9 in), reaching 2 metres (79 in) in extreme cases, and ...
The smallest nematodes are microscopic, while free-living species can reach as much as 5 cm (2 in), and some parasitic species are larger still, reaching over 1 m (3 ft) in length. [46]: 271 The body is often ornamented with ridges, rings, bristles, or other distinctive structures. [47] The head of a nematode is relatively distinct.
Parasitoid. A parasitoid wasp (Trioxys complanatus, Aphidiinae) ovipositing into the body of a spotted alfalfa aphid (Therioaphis maculata, Calaphidinae), a behaviour that is used in biological pest control [a][2] In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host's expense, eventually ...
