Lungworms are parasitic nematode worms of the order Strongylida that infest the lungs of vertebrates. The name is used for a variety of different groups of nematodes, some of which also have other common names; what they have in common is that they migrate to their hosts' lungs or respiratory tracts, and cause bronchitis or pneumonia.
Parasites often have complex life cycles and can infect humans in a number of ways including through insect vectors, contact with soil, or direct ingestion. [3] Parasites can affect the lungs in a number of mechanisms, including as a direct infection, while migrating to other organs, or through an inflammatory response to a toxin (see loeffler's syndrome).

In humans, A. cantonensis is the most common cause of eosinophilic meningitis or meningoencephalitis. [2] Frequently the infection will resolve without treatment or serious consequences, but in cases with a heavy load of parasites the infection can be so severe it can cause permanent damage to the central nervous system (CNS) or death.

Humans usually contract paragonimiasis when they eat undercooked freshwater crabs (for instance species of the genus Nanhaipotamon) or crayfish, that contain live metacercariae. In the intestine, the parasite will move into the abdomen and commonly into the lungs. In the lung, the parasites encyst and cross fertilize each other.
Spirometra erinaceieuropaei is a parasitic tapeworm that infects domestic animals and humans. The medical term for this infection in humans and other animals is sparganosis. [1] Morphologically, these worms are similar to other worms in the genus Spirometra. They have a long body consisting of three sections: the scolex, the neck, and the ...
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 ...
