\an`cy*los*to*mi"a*sis\([a^][ng]`k[i^]*l[o^]s*t[-o]*m[imac]"[.a]*s[i^]s),
   n. [NL., fr. Ankylostoma, var. of Agchylostoma, generic name
   of one genus of the parasitic nematodes.] (Med.)
   A disease caused by the hookworm parasites of the genus
   Ancylostoma (especially Ancylostoma duodenale), and
   Necator americanus. Typically, infection in humans occurs
   in the small intestine. In the small intestine they suck the
   blood from the wall and, when present in large numbers,
   produce a severe anaemia. Called also miner's anaemia,
   tunnel disease, brickmaker's anaemia, Egyptian
   chlorosis.
