Thomy-headed worm infection in north american prehistoric man

Abstract

Examination of ova and parasites from coprolites of probable human origin revealed eggs of the phylum Acanthocephala. Specimens were gathered from Danger Cave in Utah, an area heavily populatd with definitive rodent hosts for the Acanthocephala species Moniliformis clarki. It is postulated that prehistoric man developed Acanthocephala infection by ingesting the arthropod intermediate host, or that he was a victim of false parasitism by ingesting the whole rodent.
