Apr 10, 2023 · A. duodenale along with other soil-transmitted helminths (STH) are transmitted through contact with contaminated soil. In the last few decades, zoonotic transmission of 3 other Ancylostoma species has been documented. In these cases, the transmission occurred from domesticated animals to humans.

Humans are the principal host for both A. duodenale and N. americanus. A. ceylanicum may be zoonotic, as two haplotypes have been identified, one found only in humans thus far and the other found in humans, dogs, and cats. A. caninumis the common dog hookworm.
Hookworm species have a worldwide distribution, mostly in areas with moist, warm climates where larvae can survive in the environment. Both Necator americanus and Ancylostoma duodenale are found in Africa, Asia, Australia and the Americas. Only N. americanus is found in south India and predominates in the Americas, while only A. duodenaleis found i...
Intestinal hookworm infections are commonly asymptomatic. Attachment of the hookworms to the intestinal wall may stimulate abdominal pain, nausea, and anorexia. Iron deficiency anemia caused by blood loss at the site of intestinal attachment of adult worms may occur especially in heavy infections. Occult blood in the stool may also be seen in heavy...
Ancylostomiasis is infection with the hookworm Ancylostoma duodenale or Necator americanus. Symptoms include rash at the site of larval entry and sometimes abdominal pain or other gastrointestinal symptoms during early infection. Later, iron deficiency may develop because of chronic blood loss.
Jul 12, 2023 · Two types of hookworms infect humans: Ancylostoma duodenale and Necator americanus. The adult and larvae stage of the worms live in the human intestine and can spread through contaminated soil. There are two primary ways people become infected with hookworms: skin-to-soil and ingestion through contaminated food or water sources.
Transmission of A. duodenale is by contact of skin with soil contaminated with larvae. The way it enters the human body was understood in the 1880s, after an epidemic of ancylostomiasis among miners working in the hot and humid Gotthard Tunnel ( Switzerland ).

Aug 31, 2023 · There are two major species of hookworm that cause human infection: Ancylostoma duodenale (in Mediterranean countries, Iran, India, Pakistan, and the Far East) and Necator americanus (in North and South America, Central Africa, Indonesia, islands of the South Pacific, and parts of India).
Jul 16, 2021 · Background. Human hookworm disease is a common helminth infection worldwide that is predominantly caused by the nematode parasites Necator americanus and Ancylostoma duodenale; organisms that...
