Examen paleoparasitológico de sedimentos de un sitio arqueológico, Río Mayo, Chubut, Argentina

Abstract

Sediments belonging to an archaeological rescue were examined for parasites. The archaeological site consists in a rockshelter, close to Río Mayo locality, southwest of Chubut province and associated to european contact, probably s. XIX. Organic remains proceeding from the pelvic girdle were examined. By means of quantitative and qualitative techniques, eggs of anoplocephalids and nematodes, Trichuris sp., were observed. Macroscopic inspection of the sample showed rodent coprolites; the paleoparasitologic analysis exhibited eggs of anoplocephalids, Trichuris sp, Capillaria sp and an unidentified ascaridid. Probable contamination of the deposit with rodent parasites is discussed. © 2007 Sociedad Chilena de Parasitología. Organo Oficial de la Federación Latinoamericana de Parasitólogos.
