Ancylostoma
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 a state of 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. SEE ALSO: ancylostomiasis, Necator. SYN: Ankylostoma (1). [G. ankylos, curved, hooked, + stoma, mouth]
- A. braziliense a species characterized by one pair of ventral buccal teeth, normally an intestinal parasite of dogs and cats but also found in humans as a cause of human cutaneous larva migrans.
- A. caninum a species possessing three pairs of ventral teeth in the oral cavity; common in dogs, but also occurring in human skin as a cause of cutaneous larva migrans.
- A. ceylanicum species found in the civet cat of Ceylon; rarely, reported from humans as an intestinal parasite in Southeast Asia.
- A. duodenale the Old World hookworm of humans, a species widespread in temperate areas, in contrast to the more tropical distribution of the New World hookworm, Necator americanus, that is the only hookworm found in the U.S.
- A. tubaeforme a nematode species found in the cat; cutaneous larva migrans seen in humans.
