Ancylostoma

(an'si-los'tō-mă, an-ki-),
A genus of Nematoda, the Old World hookworm, the members of which are parasitic in the duodenum. They attach themselves to villi in the mucous membrane, suck blood, and may cause anemia, especially in cases of malnutrition. The eggs are passed with the feces, and the larvae develop in moist soil to become infectious third-stage (filariform) larvae that enter the human body through the skin and possibly in drinking water; they migrate by the bloodstream to lung alveoli, are carried to bronchi and trachea, swallowed, and passed to the intestine, where they mature.
