Enterobius vermicularis
The earliest known instance of Enterobius vermicularis is evidenced by pinworm eggs found in coprolite, carbon dated to 7837 BC at western Utah.[1]
Enterobius gregorii
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 had the shorter spicule (70 to 80 micrometers).[2]
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.
