Necator (nematode)

	Necator (nematode) ''Necator'' is a genus of nematodes that includes some species of hookworms. ''Necator americanus'' causes necatoriasis.

	Necator Americanus ''Necator americanus'' is a species of hookworm (a type of helminth) commonly known as the New World hookworm. Like other hookworms, it is a member of the phylum Nematoda. It is an obligatory parasitic nematode that lives in the small intestine of human hosts. Necatoriasis—a type of helminthiasis—is the term for the condition of being host to an infestation of a species of ''Necator''. Since ''N. americanus'' and ''Ancylostoma duodenale'' (also known as Old World hookworm) are the two species of hookworms that most commonly infest humans, they are usually dealt with under the collective heading of "hookworm infection". They differ most obviously in geographical distribution, structure of mouthparts, and relative size. ''Necator americanus'' has been proposed as an alternative to ''Trichuris suis'' in helminthic therapy. Morphology This parasite has two dorsal and two ventral cutting plates around the anterior margin of the buccal capsule. It also has a pair of subdorsal ...

picture info	Charles Wardell Stiles Charles Wardell Stiles (May 15, 1867 – January 24, 1941) was an American parasitologist born in Spring Valley, New York. He was notable for working on a campaign against hookworm infestation in the American South, where it had been found to cause high rates of anemia, a debilitating disease. Biography He studied science at Wesleyan University in Connecticut (1885–86), Collège de France (1886–87), the University of Berlin (1887–89) and the University of Leipzig (1889–90). In 1891, he continued his education at the zoological station in Trieste and at the Institut Pasteur in Paris. He obtained his doctorate in Leipzig under the direction of parasitologist Rudolf Leuckart (1822–1898). He taught classes in medical zoology at Johns Hopkins School of Medicine and at Georgetown University. He also worked as a zoologist for the U.S. government at the Bureau of Animal Industry in the Department of Agriculture (1891–1902), and was later chief zoologist at the Hygienic Labor ...

picture info	Hookworm Hookworms are intestinal, blood-feeding, parasitic roundworms that cause types of infection known as helminthiases. Hookworm infection is found in many parts of the world, and is common in areas with poor access to adequate water, sanitation, and hygiene. In humans, infections are caused by two main species of roundworm, belonging to the genera ''Ancylostoma'' and '' Necator''. In other animals the main parasites are species of ''Ancylostoma''. Species The two most common types of hookworm that infect humans are ''Ancylostoma duodenale'' and ''Necator americanus''. Hookworm species that are known to infect domestic cats are ''Ancylostoma braziliense'' and ''Ancylostoma tubaeforme''. Wild cats are infected by ''Ancylostoma pluridentatum''. Dogs are commonly infected by ''Ancylostoma caninum'', but may also be infected by ''Uncinaria stenocephala'' and ''Ancylostoma braziliense''. In Asia, ''Ancylostoma ceylanicum'' is endemic among dogs and cats and infects humans. Cattle ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Necatoriasis Necatoriasis is the condition of infection by '' Necator'' hookworms, such as ''Necator americanus''. This hookworm infection is a type of helminthiasis (infection) which is a type of neglected tropical disease. Signs and symptoms When adult worms attach to the villi of the small intestine, they suck on the host's blood, which may cause abdominal pain, diarrhea, cramps, and weight loss that can lead to anorexia. Heavy infections can lead to the development of iron deficiency and hypochromic microcytic anemia. This form of anemia in children can give rise to physical and mental retardation. Infection caused by cutaneous larvae migrans, a skin disease in humans, is characterized by skin ruptures and severe itching. Cause Necatoriasis is caused by '' N. americanus''. ''N. americanus'' can be divided into two areas – larvae and adult stage. The third stage larvae are guided to human skin by following thermal gradients. Typically, the larvae enter through the hands and feet fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Rhabditida Genera Rhabditida is an order of free-living, zooparasitic, and phytoparasitic microbivorous nematodes living in soil. The Cephalobidae, Panagrolaimidae, Steinernematidae, and Strongyloididae seem to be closer to the Tylenchia, regardless of whether these are merged with the Rhabditia or not.Tree of Life Web Project (2002b)Nematoda Version of 2002-JAN-01.
