Abstract
A parasitological analysis was performed using 24 dog coprolite, 1 cultural deposit, and 4 dung samples collected during excavations of the Mangazeya settlement (66°42' N, 82°16' E), the first Russian city of the 17th century (Late Holocene) in the north of Western Siberia. Helminth eggs were found in 26 (89.7%) samples. Echinochasmus sp. eggs were found in 48.3% of the samples, including the cultural deposit, 2 dung, and 11 dog coprolite samples. The genus is currently absent in the helminth fauna of the region. Helminths of the genus could have entered the region with infested dogs, pigs, and humans who migrated to the region from European Russia. A new stable natural focus of echinochasmosis did not form after the introduction, probably because of unfavorable climatic conditions of the region.
在西伯利亚西部北部的17世纪（晚全新世）第一座俄罗斯城市Mangazeya聚落（66°42' N, 82°16' E）的挖掘中收集了24块狗粪化石、1块文化沉积物和4块粪便样本，对其进行了寄生虫学分析。检出虫卵26份（89.7%）。在48.3%的样本中发现棘球绦虫卵，包括养殖沉积物、2个粪便和11个狗粪化石样本。该属目前在该地区的蠕虫动物群中不存在。该属的蠕虫可能是随着受感染的狗、猪和从俄罗斯欧洲迁移到该地区的人一起进入该地区的。引入后，可能由于该地区气候条件不利，没有形成新的稳定的棘球绦虫自然疫源地。
