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 ...
Cutaneous larva migrans (also known as creeping eruption) is a zoonotic infection with hookworm species that do not use humans as a definitive host, the most common being Ancylostoma braziliense and A. caninum.

In humans, larvae of the hookworms Ancylostoma duodenale or Necator americanus travel through the bloodstream to the lungs, penetrate the alveoli, ascend to the epiglottis, are swallowed, and then mature in the intestines.
Larvae of Ancylostoma duodenale can also cause infection when people consume food that contains the larvae. Once larvae enter the body, they move through the bloodstream to the lungs. The larvae pass into the air spaces of the lungs and move up the respiratory tract.
Apr 10, 2023 · Ancylostoma duodenale, the human hookworm, is the most common parasitic infection in countries with poor access to adequate water, sanitation, and hygiene. Anclyostoma duodenale along with other soil-transmitted helminths (STH) are transmitted through contact with contaminated soil.
Feb 21, 2018 · The two major types of hookworms that cause infection are Necator americanus and Ancylostoma duodenale. The eggs of these hookworms end up on the ground after passing through human feces.
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 of hosts such as humans, cats and dogs, where it is able to mate and mature.
Jul 16, 2021 · Human hookworm disease is a common helminth infection worldwide that is predominantly caused by the nematode parasites Necator americanus and Ancylostoma duodenale; organisms that play a...
The human hookworms include the nematode species, Ancylostoma duodenale and Necator americanus. A larger group of hookworms infecting animals can invade and parasitize humans (A. ceylanicum) or can penetrate the human skin (causing cutaneous larva migrans), but do not develop any further (A. braziliense, A. caninum, Uncinaria stenocephala).
