Peruvian and Chilean mummies and coprolites provide a source of population-based parasitological information. This is especially true of the fish tapeworm, Adenocephalus pacificus. Our analysis of Chinchorro and Chiribaya mummies and diversified coprolite samples from Chile and Peru show variation in infection. There is a statistically significant difference in prevalence between Chinchorro hunter-gatherer and Chiribaya mixed-subsistence contexts. Furthermore, the most pronounced differences occur between populations within these groups. Chinchorro differences in cemeteries at the same location can be related to El Niño–Southern Oscillation variations. Pronounced prevalence variations between 3 Chiribaya villages within 7 km of each other relate to fish distribution and preparation variation. As with other recent archaeoparasitology studies, eggs-per-gram data exhibit overdispersion.

秘鲁和智利的木乃伊和粪化石提供了基于人群的寄生虫学信息的来源。对于鱼类绦虫（Adenocephalus pacificus）来说尤其如此。我们对新克罗木乃伊和奇里巴亚木乃伊以及来自智利和秘鲁的各种粪化石样本的分析显示了感染的差异。新克罗狩猎采集者和奇里巴亚混合生活环境之间的流行率存在统计学上的显着差异。此外，最明显的差异发生在这些群体内的人群之间。同一地点墓地的新克罗差异可能与厄尔尼诺-南方涛动变化有关。相距 7 公里以内的 3 个 Chiribaya 村庄之间明显的患病率差异与鱼的分布和制备差异有关。与最近的其他考古寄生虫学研究一样，每克卵数数据表现出过度分散。
