Résumé
"Molecular study of Trypanosoma cruzi (T. cruzi) anciant DNA (aDNA) in the soft (nonskeletal) tissues of 283 naturally(spontaneously) mummified bodies from coastal sites located in southern Peru and northern Chile demonstrated a Chagas diseaseprevalence rate of about 41% over the past 9,000 years. This rate is similar to that of several endemic areas within this region priorto initiation of public health control programs. This report focuses on the presence of T. cruzi aDNA in the coprolites of some ofthese mummies. Review of the possible mechanisms that may explain the presence of this parasite in the coprolites indicatesnumerous antemortem and postmortem circumstances that conceivably could have been responsible. In given conditions, all ofthese may need to be considered. These considerations indicate that the presence of T. cruzi aDNA in mummy coprolites cannotcategorically be considered as evidence of ingestion of the parasite."
