Parasitology A hematophagous nematode of family Ancylostomatidiae–eg, Old World hookworm–Ancylostoma duodenale and New World hookworm–Necator americanus that sensitizes the penetration site–eg, skin, causing 'ground itch', or lungs–eg, Loeffler syndrome as the worms wiggle through, causing eosinophilia and, due to bloodsucking, anemia Lab Rhabditidiform larvae may be confused with Strongyloides stercoralis; eggs may be confused with Trichostrongylus and Meloidogyne spp. See Ancylostoma duodenale, Necator americanus.
