Endoscopic Discovery and Capture of Necator americanus in the Stomach
Endoscopy, 1983We report a case of the endoscopic discovery and removal of a specimen of Necator americanus hooked into the gastric mucosa of a black woman from Zaire. We extracted the parasite by means of biopsy forceps. Signs of previous bites were seen in the antrum. This exceptional localization might be due to a jejuno-duodeno-gastric reflux.

Sequence data mining in search of hookworm (Necator americanus) microRNAs.
Gene, 2016The new world hookworm, Necator americanus is a soil-transmitted nematode responsible for Necatoriasis (a type of helminthiasis) in hosts such as humans, dogs, and cats. N. americanus genome and transcriptome has been sequenced and a draft assembly analysis has been published highlighting protein coding genes and possible drug target proteins. Hookworm

Skin penetration byNecator americanus larvae
Zeitschrift f�r Parasitenkunde Parasitology Research, 1982Skin penetration by Necator americanus larvae has been investigated in vitro. Larvae were able to penetrate completely human skin from both the epidermal and dermal directions; their passage through the epidermis was marked by cellular destruction.

Genes and genomes of Necator americanus and related hookworms
International Journal for Parasitology, 2000The human hookworms (Necator americanus and Ancylostoma duodenale) infect over one billion people. The phylogenetic relationships of the human hookworms suggest independent acquisition of the human host. The hookworms probably have a haploid chromosome number n = 6, and an XX-XO sex determination mechanism is likely to be used.

The exsheathment of Necator americanus infective larvae.
The Southeast Asian journal of tropical medicine and public health, 2007Infective 3rd-stage larvae of Necator americanus were treated with human sweat under various conditions, and compared with human serum, 1.5% saline solution, and distilled water. The infective larvae were observed under inverted microscopy. The highest percentage (14.0%) of the exsheathed larvae was found in human sweat after 2 hours' incubation at 37 ...

The immunogenicity of hookworm (Necator americanus) acetylcholinesterase (AChE) in man
Parasite Immunology, 1993SummaryA number of different but complementary approaches have been used to demonstrate the immunogenicity of Necator americanus acetylcholinesterase to infected individuals. Western blotting of parasite somatic extracts with human post‐infection sera and a specific rabbit antiserum to AChE resulted in the development of almost identical antigen ...

Secretion of Metalloproteases by Living Infective Larvae of Necator americanus
The Journal of Parasitology, 1992Fresh living third-stage larvae of Necator americanus released a significant amount of label within 2 hr of their incubation on 125I-labeled gelatin-coated polystyrene plastic plates. This protease activity was primarily susceptible to o-phenanthroline, which identifies the activity as predominantly metalloprotease.

Site of resistance to Necator americanus in hamsters.
Acta tropica, 1986Resistance to the development of human hookworm, Necator americanus was examined in 3- to 6-week-old young adult hamsters. Only 3% of N. americanus infective third stage larvae (NaL3) reached maturity in the intestines of young adults as opposed to as many as 60% in 2-day-old baby hamsters. This seemingly effective resistance prevailing in young adults

Necator americanusand the Domestic Pig
Journal of Helminthology, 1923The occurrence of Ankylostomes resembling human hookworms in the domestic pig has been the subject of several recent papers, the most noteworthy being the contributions of Ackert and Payne (1922 and 1923) and Gordon (1922 and 1923).
