متن کاملPaleoparasitology: perspectives with new techniques.
Paleoparasitology is the study of parasites found in archaeological material. The development of this field of research began with histological identification of helminth eggs in mummy tissues, analysis of coprolites, and recently through molecular biology.

However, in a parasitic disease the presence of a given parasite is always necessary, at least in a given moment of the infection. Some...
متن کاملQuantitative paleoparasitology applied to archaeological sediments.
Three techniques to extract parasite remains from archaeological sediments were tested. The aim was to improve the sensibility of recommended paleoparasitological techniques applied in archaeological remains. Sediment collected from the pelvic girdle of a human body found in Cabo Vírgenes, Santa Cruz, Argentina, associated to a Spanish settlement founded in 1584 known as Nombre de Jesús, was us...

However, our knowledge abo...
