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 work environment often contained standing water, sometimes knee-deep, and the larvae were capable of surviving several weeks in the water, allowing them to infect many of the workers. In 1897, it was established that the skin was the principal avenue of infection and the biological life cycle of the hookworm was clarified.
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 ...

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 caninum is a species of nematode known as a hookworm, which principally infects the small intestine of dogs. [ 1 ] [ 2 ] [ 3 ] The result of A. caninum infection ranges from asymptomatic cases to death of the dog; better nourishment, increasing age, prior A. caninum exposure, or vaccination are all linked to improved survival.
