Two common hookworm infections in humans are ancylostomiasis and necatoriasis, caused by the species Ancylostoma duodenale and Necator americanus respectively. Hookworm eggs are deposited in the stools of infected people. If these end up in the environment, they can hatch into larvae (immature worms), which can then penetrate the skin. One type ...
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.
In humans, treatment is by anthelminthic medications, such as albendazole and mebendazole. [13] Treatment in animals can be done with a variety of anthelminthics. [1] A high-protein diet, supplemental iron, or a blood transfusion may also be necessary. [1] Levamisole and pyrantel pamoate are also used to treat hookworm anemia and hookworm disease.

The key ...

The hookworms, Necator americanus and Ancylostoma duodenale, hatch as first-stage juveniles within the soil and develop to an infective third-stage juvenile.Infection occurs by direct penetration through the skin of the host.
