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 ...
Once the mantis ingests the infected insect, the C. formosanus starts to grow. When it is mature, the worm secretes proteins that take over the host's nervous system, which directs the mantis to a body of water and causes it to jump in so that the worm can be excreted, at which point it breaks free to reproduce leaving a half empty mantis husk.

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 providing the means for the parasitic species to exit ...
Gongylonema pulchrum infections are due to humans acting as accidental hosts for the parasite. There are seven genera of spirudia nematodes that infect human hosts accidentally: Gnathostoma, Thelazia, Gongylonema, Physaloptera, Spirocerca, Rictularia. The G. pulchrum parasite is a nematode worm of the order Spirurida. It is a relatively thin ...
This parasite is known to infect insect species in the order orthoptera. Amongst the host species are grasshoppers, crickets, cockroaches, snails, mosquito larvae, or other small aquatic animals and insects. Mammals are not capable of being infected. However, dogs, cats, and even humans have been known to swallow adult worms accidentally. [7]

Once ingested by the insect the worm larva penetrates the gut wall and develops in a cyst in the tissue outside. [4] It emerges as an adult worm in a few months. [3] Gordius worms have been recovered from human vomit, [7] feces, [8] and urine. When worms are expelled from the gastrointestinal tract, their mode of entry was likely ingestion of ...
