Intestinal hookworm disease in humans is caused by Ancylostoma duodenale, A. ceylanicum, and Necator americanus. Classically, A. duodenale and N. americanus were considered the two primary intestinal hookworm species worldwide, but newer studies show that a parasite infecting animals, A. ceylanicum , is also an important emerging parasite ...

Ancylostoma duodenale is a species of the roundworm genus Ancylostoma. It is a parasitic nematode worm and commonly known as the Old World hookworm.
