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.
Hookworm life cycle. The host is infected by the larvae, not by the eggs, and the usual route is through the skin. Hookworm larvae need warm, moist soil, above 18 °C, in order to hatch. They will die if exposed to direct sunlight or if they become dried out. Necator larvae can survive at higher temperatures than Ancylostoma larvae. [citation ...

Since N. americanus and Ancylostoma duodenale (also known as Old World hookworm) are the two species of hookworms that most commonly infest humans, they are usually dealt with under the collective heading of "hookworm infection". They differ most obviously in geographical distribution, structure of mouthparts, and relative size. [2]
Hookworm diseases (ancylostomiasis and necatoriasis), which are caused by Necator americanus and Ancylostoma duodenale Trichuriasis , which is caused by Trichuris trichiura Soil-transmitted helminthiasis is classified as one of the neglected tropical diseases projected to be controlled/eradicated by 2020 through the London Declaration on ...
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.
Ancylostoma ceylanicum is a parasitic roundworm belonging to the genus Ancylostoma. It is a hookworm both of humans and of other mammals such as dogs , cats , and golden hamsters . It is the only zoonotic hookworm species that is able to produce symptomatic infections in humans, with the majority of cases being in Southeast Asia .
Cutaneous larva migrans (abbreviated CLM) is a skin disease in humans, caused by the larvae of various nematode parasites of the hookworm family (Ancylostomatidae).The parasites live in the intestines of dogs, cats, and wild animals; they should not be confused with other members of the hookworm family for which humans are definitive hosts, namely Ancylostoma duodenale and Necator americanus.
