Infec??o por Enterobius vermicularis em popula??es agro-pastoris pré-colombianas de San Pedro de Atacama, Chile

摘要

Enterobius vermicularis eggs were found in human coprolites collected from the archaeological site of San Pedro de Atacama, North of Chile, in occupational layers dated from 1,000 BC. Agricultures and herding were begining at this period of time in this region of South America. The paleoparasitological data amplifies the knowledge about the distribution of human oxyuriasis in Pre-Columbian America.
