|Contribution||Wrote medical text that included mention of various parasitic worms.|
|Notes||Ibn Sina, known in the West as Avicenna, mentioned worms that appear to include tapeworms and nematodes including ascarids, pinworms and Dracunculus medinensis. The date is approximate. The reference is: M. Cordero del Campillo, Vet. Parasitol. 33: 93-116, 1989. See also Grove. This is one of many accounts of macroparasites in antiquity. See the more precisely dated 1379 Brie for the reason for including a few, but only a few, such records in the Germ Theory Timeline.|
