“…Echinococcus sp. findings have been reported in both the New and the Old World, but mainly as taeniids, except when molecular confirmation of the genera was achieved (Côté et al 2016; Gonçalves et al 2003; Paknezhad et al 2017; Reinhard 1990; Wilke and Hall 1975). Oviposition of these helminths differs importantly.…”

We conducted a paleoparasitological study on sediment samples from two trash pits and a cesspool, collected during an archaeological assessment of a building located in the historic downtown of the city of Córdoba, Argentina. People have used these premises for residential and commercial purposes since the beginning of the seventeenth century, although the samples analyzed correspond to nineteenth-century contexts. Light microscopy examination revealed the presence of parasite eggs of whipworm (Trichuris sp.), possibly roundworm (Ascaris lumbricoides), and tapeworm (taeniid). The presence of these fecal-oral and food-borne transmitted helminths supports other lines of evidence that indicate poor sanitation and hygiene habits and inadequate food processing, which may have contributed to the high incidence and mortality of gastrointestinal diseases recorded at that time. The paleoparasitological data agree with the historical information on the health status of the populations that inhabited the city of Córdoba in the past, especially in relation to their habits and diet.

“…Parasitic particles from archaeo‐anthropological materials denounce a status of zoonosis, whose existence is established starting from Neolithic domestication events and sharing of living areas (Mazoyer & Roudart, 2006). Worldwide reports of helminth eggs have been reported for populations of Fertile Crescent (Diamond, 2002; Driscoll et al., 2009; Zeder, 2008), Western Iran (Paknezhad et al., 2017) and Atacama Desert (northern Chile) (Ramirez et al., 2021). The discovery of several cestode eggs in the dental calculus of an individual buried in the Pila cave could seem counterintuitive.…”

Plants have always represented a key element in landscape delineation. Indeed, plant diversity, whose distribution is influenced by geographic/climatic variability, has affected both environmental and human ecology. The present contribution represents a multi‐proxy study focused on the detection of starch, pollen and non‐pollen palynomorphs in ancient dental calculus collected from pre‐historical individuals buried at La Sassa and Pila archaeological sites (Central Italy). The collected record suggested the potential use of plant taxa by the people living in Central Italy during the Copper‐Middle Bronze Age and expanded the body of evidence reported by previous palynological and palaeoecological studies. The application of a microscopic approach provided information about domesticated crops and/or gathered wild plants and inferred considerations on ancient environments, water sources, and past health and diseases. Moreover, the research supplied data to define the natural resources (e.g., C4‐plant intake) and the social use of the space during that period. Another important aspect was the finding of plant clues referable to woody habitats, characterised by broad‐leaved deciduous taxa and generally indicative of a warm‐temperate climate and grassy vegetation. Other unusual records (e.g., diatoms, brachysclereids) participated in defining the prehistoric ecological framework. Thus, this work provides an overview on the potential of the human dental calculus analysis to delineate some features of the ancient plant ecology and biodiversity.

“…Although DNA of E. multilocularis was not identified in this study, the detection of DNA of other taeniids of foxes reveals that feed potentially pose a source for E. multilocularis eggs. So far, methods used to estimate the environmental or food contamination with taeniid eggs/DNA are not allowing to assess their viability, and hence, the results of such studies have to be carefully interpreted, especially considering that parasite DNA (e.g., Trichuris) [93] and also taeniid eggs [94] can be detected in archeological samples.…”

Purpose of Review Cystic and alveolar echinococcosis, caused by Echinococcus granulosus sensu lato and E. multilocularis, respectively, and Taenia solium cysticercosis are serious but neglected zoonotic diseases, caused by extra-intestinal cestode (tapeworm) infections. Humans are dead-end hosts for Echinococcus spp and acquire the infections by uptake of parasite eggs, either with contaminated food or via exposure by hand-mouth contact to eggs derived from the contaminated environment, including skin or coat of definitive hosts. Data related with the production of eggs of these parasites, their survival in the environment and the methodology for detection in food and environmental samples are summarized.Recent Findings The detection of taeniid DNA, more specifically from E. multilocularis, in food and soil has recently been described in some European countries. These findings have been directly connected with an increase in prevalence of human infections in countries like Poland. Summary The isolation and molecular identification of taeniid eggs is technically challenging and little standardized. The detection of taeniid DNA per se does not imply viability of eggs, and this must be considered when interpreting molecular results for transmission risk. Finally, easy, affordable, and sensitive methods replacing animal experiments should be developed to assess the viability of taeniid eggs isolated from environmental and food/water sources.
