ABSTRACT

Exploratory examinations were performed in sediments of archaeological levels from Cerro Casa de Piedra, cave 7 (CCP7). The aim of the present study was to identify parasitic remains present in the floor where human occupation has been reported. Parasite remains of Eimeria macusaniensis, molineids and two capillariids nematodes were identified. A single oocyst of Eimeria ivitaensis was found, resulting in the first report from Patagonia. Parasites found in this work were previously reported in camelid coprolites. Parasitological findings showed camelids presence into the cave and a high contamination of domestic area. These findings reinforce the hypothesis about the role of caves in parasites circulation among mammals community of Patagonia.

摘要

在Cerro Casa de Piedra 7 号洞穴 (CCP7)的考古层沉积物中进行了探索性检查。本研究的目的是确定据报告有人居住的地板上是否存在寄生虫遗骸。鉴定出澳门艾美耳球虫、拟线虫和两种毛细线虫的寄生虫遗骸。发现了艾美耳球虫的单个卵囊，这是巴塔哥尼亚的第一份报告。这项工作中发现的寄生虫之前曾在骆驼科粪化石中报道过。寄生虫学调查结果显示，洞穴中存在骆驼科动物，且居住区域受到高度污染。这些发现强化了关于洞穴在巴塔哥尼亚哺乳动物群落寄生虫循环中的作用的假设。
