Historical Perspective
The earliest known instance of pinworms is evidenced by pinworm eggs found in coprolite, carbon dated to 7837 BC at western Utah.
Enterobius gregorii
The pinworm Enterobius gregorii is a parasitic roundworm of the phylum Nematoda.
In 1983 Jean-Pierre Hugot declared his isolation of a new human parasite. While examining oxyuridae of Malagasy Lemurs and in Old World monkeys, he concluded that what had been previously assumed to be a single species of parasite was in fact couples of sister-species. Two types of spicules were described, Enterobius vermicularis (L., 1758) having the larger spicule (100 to 122 micrometers), and Enterobius gregorii n. sp. had the shorter spicule (70 to 80 micrometers).
This fine distinction is only of minor importance to all but the most statistically-minded researcher, however. For all practical purposes, the morphology, life cycle, clinical presentation, and treatment of Enterobius gregorii is identical to Enterobius vermicularis.
