Ancylostomiasis is infection with the hookworm Ancylostoma duodenale or Necator americanus. (See also Approach to Parasitic Infections.) The estimated worldwide prevalence of hookworm infection is 576 to 740 million, mostly in developing areas. Both A. duodenale and N. americanus occur in Africa, Asia, and the Americas.. Hookworm disease from Necator americanus and Ancylostoma duodenale affects approximately 700 million people, with N. americanus being the predominant species. Unlike other pathogens (e.g., bacterial infections), where “virulence” is described in regards to acute pathogenesis and case-fatality, hookworms are well-evolved, multicellular.

Human hookworm disease is a common helminth infection that is predominantly caused by the nematode parasites Necator americanus and Ancylostoma duodenale; organisms that play a lesser role include Ancylostoma ceylonicum,Ancylostoma braziliense, and Ancylostoma caninum. Hookworm infection is acquired through skin exposure to larvae in soil con.. Ancylostoma duodenale: Necator americanus: Size: Longer: Shorter: Blood loss: 10.20 mL/day 0.03 mL/day: Life Span: 1-2 years: 3-5 years or more: Egg production: 10,000 to 25000 /day 5000 to 10,000/day Mode of Transmission: Skin penetration and ingestion: Skin penetration only : Buccal capsule: Ancylostoma contains sharp teeth. Necator contains.
