An·cy·los·to·ma du·o·de·na·'le

the Old World hookworm of humans, a species widespread in temperate areas, in contrast to the more tropic distribution of the New World hookworm, Necator americanus, which is the only hookworm found in the U.S.

Ancylostoma duodenale

The only hookworm native to the US, which enters the body as a 3rd-stage larva through breaks in the skin (e.g., bare feet in contact with contaminated soil); once in the circulation, larvae migrate to the pulmonary alveoli, where they are coughed up and swallowed, then enter the duodenum and attach themselves to the intestinal villi.

Clinical findings
Intense pruritus, erythema and a vesicular rash at the site of larval penetration; anaemia; malnutrition.
 
Management
Mebendazole; iron for anaemia.
