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 americanus: Activity patterns in the egg and the mechanism of hatching
Experimental Parasitology, 1974Abstract Necator americanus developed normally in distilled water and in solutions of up to 4% NaCl, hatching however, occurred only in the lower tonicities. Together with other observations, this led to the conclusion that, as with many other nematodes, osmotic changes were critical for emergence.

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 ...

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).
