Abstract
The occurrence of certain parasites in human groups from different regions has been used to study the geographical origin of both hosts and parasites. The presence of hookworm infection in an isolated tribe in remote regions of Paraguay led to speculations about its origin, since the prehistoric migrations through the Behring Land Bridge could not have brought the parasite, which needs for its mantenance a temperature of about 22ºC in the soil. It was then proposed that only transpacific migrations of Asiatic populations could have brought the parasite to America. This discussion dates back to the beginning of this Century and it was only with recent paleoparasitological findings that it arose again. This paper is a review of hookworm findings in archaeological material and suggests possible routes followed by their hosts to reach the New World.
A ocorrência de certos parasitos em grupos humanos de diferentes regiões tem sido usada para o estudo da origem geográfica tanto da população humana como de seus parasitos. A presença da ancilostomose, em tribos isoladas de regiões remotas do Paraguai, levou a especulações sobre a sua origem, uma vez que as migrações pré-históricas pelo caminho de Bering não poderiam ter sido responsáveis pela introdução do parasito que necessita, para sua manutenção no solo, de temperatura em torno de 22ºC. Propôs-se então que somente migrações transpacíficas de populações asiáticas poderiam ter intoduzido o parasito na América. Esta discussão data do início do século e somente com os recentes achados da paleoparasitologia foi retomada novamente. Este trabalho é uma revisão sobre o encontro de ancilostomídeos em material arqueológico e sugere possíveis rotas seguidas pelos hospedeiros para alcançar o Novo Mundo.
