Drugs are frequently used to kill parasites in the host. In earlier times, turpentine was often used for this, but modern drugs do not poison intestinal worms directly. Rather, anthelmintic drugs now inhibit an enzyme that is necessary for the worm to make the substance that prevents the worm from being digested. [citation needed]
A nematode infection is a type of helminthiasis caused by organisms in the nematode phylum. [1] An example is enterobiasis. Several antinematodal agents are available.
Ancylostoma duodenale is a species of the roundworm genus Ancylostoma.It is a parasitic nematode worm and commonly known as the Old World hookworm. It lives in the small intestine especially the jejunum [citation needed] of definitive hosts, generally humans, [2]: 307–308 [3] where it is able to mate and mature.
The most common treatments for hookworm are benzimidazoles, specifically albendazole and mebendazole. BZAs kill adult worms by binding to the nematode's β-tubulin and subsequently inhibiting microtubule polymerization within the parasite. [14] In certain circumstances, levamisole and pyrantel pamoate may be used. [12]
The worms mate inside the host, in which the females also lay their eggs, to be passed out in the host's feces into the environment to start the cycle again. N. americanus can lay between nine and ten thousand eggs per day, and A. duodenale between twenty-five and thirty thousand per day.
Loa loa filariasis, (Loiasis) is a skin and eye disease caused by the nematode worm Loa loa.Humans contract this disease through the bite of a deer fly (Chrysops spp.) or mango fly, the vectors for Loa loa.
The most prescribed treatment for gnathostomiasis is surgical removal of the larvae but this is only effective when the worms are located in an accessible location. [1] In addition to surgical excision, albendazole and ivermectin have been noted in their ability to eliminate the parasite. [ 3 ]
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 nematode, and like other worms within its class, it has no circulatory or respiratory system.
