(zoology) A genus of hookworm of the family Ancylostomatidae, e.g. Necator americanus

(mycology) A genus of fungus of the family Corticiaceae, e.g. Necator decretus


In zoology, Necator is a genus belonging to the family Ancylostomatidae. It is a hookworm that parasitizes animals. An example of this is Necator americanus, which is human hookworm. It is one of the genera of hookworms that infest humans. Another is Ancylostoma (particularly A. duodenale). Necator americanus is very similar to the A. duodenale when it comes to morphology. Nevertheless, N. americanus is smaller than A. duodenale and the former has a pair of cutting plates in the buccal capsule. N. americanus has a more defined hook shape than Ancylostoma.1

Another is Necator suillus, which is a hookworm found in pigs. These species are intestinal parasites, feeding on blood in the intestines of their hosts. Infestation with Necator hookworms is referred to as necatoriasis.

In mycology, Necator is a genus of the family Corticiaceae. Corticiaceae is a family of fungi that includes mainly a group of corticioid genera (i.e. patch- or crust-forming fungi). One species belonging to the genus Necator is reported, i.e. Necator decretus. This fungal species is found in Southeast Asia.2
