Abstract

Little is known of helminth parasites in Micronesia in archaeological contexts. This study presents a parasitological analysis of soil and sediment samples from Ebon Atoll in the Marshall Islands, eastern Micronesia. Microscopic eggs of the dog (Canis lupus familiaris) nematode Toxocara canis, which could have adversely affected the health of local people as well as their dogs, were found at two sites, in one example in habitation layers dated to 1830–1625 calBP (95% CI), extending the date for the known presence of dogs in the Marshall Islands by at least 600 years. This study represents the first confirmed evidence of pre-European helminth parasites in Micronesia. As similar Melanesian and Polynesian studies have previously been reported, the study also completes the initial, pre-contact helminth record for the three main island regions of Oceania.

密克罗尼西亚的寄生虫新发现:马绍尔群岛埃本环礁考古遗址中的犬线虫虫卵将已知狗的存在时间延长了约 600 年
人们对密克罗尼西亚考古环境中的蠕虫寄生虫知之甚少。本研究对密克罗尼西亚东部马绍尔群岛埃本环礁的土壤和沉积物样本进行了寄生虫学分析。在两个遗址中发现了狗线虫Toxocara canis的显微虫卵,这种虫卵可能会对当地人和他们的狗的健康产生不利影响,其中一个遗址的居住层的年代为1830-1625 calBP(95% CI),这将马绍尔群岛已知有狗存在的年代延长了至少600年。这项研究首次证实了密克罗尼西亚在欧洲之前存在蠕虫寄生虫的证据。类似的美拉尼西亚和波利尼西亚研究之前也有报道,因此这项研究也完成了大洋洲三个主要岛屿地区接触前蠕虫的初步记录。

期刊介绍: Archaeology in Oceania is published online and in print versions three times a year: April, July, October. It accepts articles and research reports in prehistoric and historical archaeology, modern material culture and human biology of ancient and modern human populations. Its primary geographic focus is Australia, the islands of the Pacific Ocean and lands of the western Pacific rim. All articles and research reports accepted as being within the remit of the journal and of appropriate standard will be reviewed by two scholars; authors will be informed of these comments though not necessarily of the reviewer’s names.
