Necator

A genus of nematode hookworms (family Ancylostomatidae, subfamily Necatorinae) distinguished by two chitinous cutting plates in the buccal cavity and fused male copulatory spicules. Species include N. americanus, the so-called New World hookworm (although it is also prevalent in the tropics of Africa, southern Asia, and Polynesia); the adults of this species attach to villi in the small intestine and suck blood, causing abdominal discomfort, diarrhea (usually with melena) and cramps, anorexia, loss of weight, and hypochromic microcytic anemia, which may occur in advanced disease. SEE ALSO: Ancylostoma. [L. a murderer]
