“…The coprolites recovered from archaeological sites are valuable sources for identification of the parasites that were prevalent in ancient times; however, well-preserved coprolites are not much available (7,8). The present study reports the identification of two helminths eggs in the well-preserved ungulate coprolites from Chehrabad salt mine of Zanjan, North West of Iran.…”

“…The parasitic worms of equids such as strongyles have a worldwide distribution (2)(3)(4)(5)(6), while the available data of their presence in ancient times is very scarce (7,8). Strongyle nematodes are amongst the most prevalent pathogenic helminth inhabiting the large intestine of herbivores.…”
Background: The ancient Chehrabad Salt mine, a well-known archaeological site in Iran, has recently received increasing interest from Iranian and international archeologists. Also, the biological remains from this site have provided valuable sources for studying the pathogenic agents of ancient times. This study aimed to identify the parasitic helminth eggs preserved in the herbivores coprolites.
Methods: From 2011 to 2015, we received three coprolites belonging to herbivorous animals recovered during excavations in Chehrabad Salt mine of Zanjan, Iran. The coprolites were dated back to the Sassanid era (224-651 AD) by using radiocarbon accelerator mass spectrometry (AMS) and archeological stratigraphy methods. Following rehydration of the specimens in a 0.5% trisodium phosphate solution, the suspensions were mounted in glycerin jelly on glass slides and examined by a light microscope with 100x and 400x magnifications.
Results: Two coprolites belonged to donkeys and one to an unknown herbivore species. The recovered eggs belonged to members of two helminths families, Strongylidae, and Anoplocephalidae. Also, within the two coprolites, some mites, presumably of the order Oribatida, were observed.
Conclusion: The presence of two different nematodes in the equids coprolites provide clues of the burden of helminths infection on working animal at the Sassanid time and demonstrates the appropriate preservation condition of biological remains in the ancient salt mine of Chehrabad as well.

“…Similarly, Dufour et al (95) published a synthesis on the horse pinworm, Oxyuris equi, in archaeology and showed that the parasite had been present in central Europe from c. 2500 BP. It seems to have diffused into western Europe by way of the horse migration that accompanied humans, in particular during the Roman period.…”

This chapter aims to provide some key points for researchers interested in the study of ancient gastrointestinal parasites. These few pages are dedicated to my colleague and friend, Prof. Adauto Araújo (1951-2015), who participated in the writing of this chapter. His huge efforts in paleoparasitology contributed to the development and promotion of the discipline during more than 30 years.
“…Over the past years, an increasing number of analyses have been performed on non-human materials, opening up the study of ancient animal (non-human) parasitic diversity (Beltrame et al., 2011, 2014, 2015a, 2015b, 2017, 2018; Borba-Nunes et al, 2017; Dentzien-Dias et al., 2013; Dufour et al., 2015; Fugassa et al., 2018; Le Bailly and Bouchet, 2010; Leles et al., 2018; Sianto et al., 2012, 2014; Slepchenko and Reinhard, 2018; Vieira de Souza et al., 2012; Wood et al., 2013). In such contexts, parasites can be used as evidence for animal presence, and shed light on the spread of parasitic species in wild fauna through time.…”
This paper presents an original palaeoparasitological study performed on samples from a sedimentary core in a peat bog (Asi Gonia, White Mountains, Crete, Greece). The aim of the study is to test the preservation and concentration of parasitic remains in peat sediments, to discuss animal presence around the site throughout the record, and to compare the results with other biomarkers of environmental history. In this aim, 22 sediment samples distributed between the Roman period and the present were processed and the residues were observed under light microscopy in search of parasitic markers (microscopic eggs or oocysts). The majority of the samples (86.4%) tested positive for the presence of helminth eggs. Several taxa were observed throughout the studied period, including Trichuris sp., Ascaris sp., Capillaria sp., Fasciola sp., Paramphistomum sp. and Macracanthorhynchus sp. The assemblage of parasite markers changes throughout the record and the variations show close correlations with previously published grazing indicators (fungal spores) and vegetation changes (pollen grains). This study sheds lights on animal associations and changing environments in the watershed over the past 2000 years. Indeed, we detected three main phases consisting of: Roman animal herding with pigs in an evergreen oak forest, then a more irregular but almost constant presence of ruminants during a second Byzantine and modern phase in a heather maquis landscape and, finally, present-day grazing in a phrygana/steppe landscape. These results highlight how palaeoparasitology can contribute to multi-proxy approaches in peat bog sedimentary sequences.
