To analyze the presence of protozoan parasites in bird coprolites from the Tremembé Formation (Oligocene of the Taubaté Basin). Twenty avian coprolites embedded in pyrobituminous shale matrices. Samples were rehydrated and subjected to spontaneous sedimentation. Paleoparasitological analyses revealed oocysts compatible with the Eimeriidae family (Apicomplexa) and one single Archamoebae (Amoebozoa) cyst. The present work increases the amount of information about the spread of infections throughout the Cenozoic Era and reveals that the Brazilian paleoavifauna played an important role in the Apicomplexa and Amoebozoa life cycles. This is the first record of protozoans in avian coprolites from the Oligocene of Brazil. These findings can help in the interpretation of phylogenies of coccidian parasites of modern birds, as certain taxonomic characters observed in the Oligocene Protozoa characterize monophyletic groups in current molecular phylogenetic analyses. None of the oocysts were sporulated; therefore, it is not possible to identify the morphotypes to genus or species. Our results create new perspectives related to biogeographic studies of the parasitic groups described and may improve the understanding of the temporal amplitude of parasitic evolutionary relationships between Protozoans and birds. • Paleoparasitological analyzes in twenty Oligocene avian coprolites from Brazil were performed. • We report the first records of Eimeriidae and Archamoebae in avian coprolites from the Tremembé Formation. • The Oligocene birds from the Paraiba Valley were important for spreading of Eimeriidae and Archamoebae infections.

The optimization of techniques for recovering parasitic remains is key in paleoparasitology. The Mini-FLOTAC technique (MF) is based on passive flotation and is used for diagnosis of parasites and was never tested on ancient samples. Our objective was to assess the effectiveness of MF in paleoparasitology, aiming at improving the techniques for the recovery of parasitic remains in order to upgrade the interpretative potential of the paleoparasitological evidence. Three techniques were tested: MF, spontaneous sedimentation (SS), and centrifugation-sucrose flotation (CF) testing camelid and goat coprolites. Statistical tests were performed with the R software. Our result displayed that, in the case of SAC samples, MF recovered less number of parasitic species than SS, but obtained a greater number of positive samples for protozoa. For goat samples, MF recovered a higher number of positive samples and parasitic species than SS, added that it was the technique that recovered a greater number of parasite structures. Therefore, results vary according to the zoological origin of the samples and the parasitic species recorded. We suggest starting using MF on ancient samples as a complementary method to those traditionally used in paleoparasitology. It is important to highlight that MF was a simple and faster way. The incorporation of reliable quantitative techniques opens the door to a new way of analyzing archaeological remains, deepening the study of the parasite-host relationships and its evolution through time with an epidemiological approach. Although further studies are needed, our results suggest the complementarity of these techniques in future paleoparasitological studies. [ABSTRACT FROM AUTHOR]

To evaluate the prevalence of gastro-intestinal parasites in human remains from Late Antiquity (5th – 7th c.) Granada (Spain). The study included pelvic and cranial control samples from 17 skeletons from the archaeological sites of Los Mondragones (n = 13) and Rafael Guillén (n = 4). In the paleoparasitological study, soil samples from pelvic area and cranium were analyzed using the rehydration, homogenization, and micro-sieving method and visualization under brightfield microscopy. Ascaris sp. eggs were detected in pelvic samples from seven individuals. These findings may indicate that this parasite was endemic. Its detection frequency is one of the highest reported at group level in an osteological series from Late Antiquity. The prevalence of Ascaris sp. associated with skeletal remains has implications for assessing the lifestyle and health of populations in southern Spain during the Late Antique period. The number of individuals is small and taphonomic processes could have limited paleoparasitological findings Future interdisciplinary studies of this type are warranted in larger osteological series to improve knowledge of parasitosis in the past.

Recent efforts have been made to review the state of the art on a variety of questions and targets in paleoparasitology, including protozoan taxa. Meanwhile, these efforts seemed to let aside Cryptosporidium, and we then intended to review its paleoparasitological record to assess its past distribution and favored detection methods, and eventually highlight needed research trajectories. This review shows that contrary to other parasites, most of the positive results came from South-American sites and coprolites rather than sediment samples, highlighting the need to test this kind of material, notably in Europe where many negative results were reported in the published literature from sediment samples. Moreover, aDNA-based detections are nearly absent from the paleoparasitological record of this parasite, though punctually shown successful. With their potential to address the evolutionary history of Cryptosporidium species, notably through their 18S rRNA tree, aDNA-based approaches should be encouraged in the future. In sum, and though the limits of currently used methods and materials remain unclear, this review highlights the potential role of coprolites and aDNA for the study of Cryptosporidium species in the past and how this history shaped their current diversity and distribution, notably among human populations but also farm animals.

Paleoparasitology is a discipline that applies existing conventional and molecular techniques to study parasites found in ancient ruins. This review focuses on the history of the discovery of parasites (mostly helminth eggs and larvae) in archaeological soil samples and mummies in Korea from the Three Kingdoms Period to the Joseon Dynasty (100 BCE-1910 CE). We also briefly review important milestones in global paleoparasitology. The helminth species reported so far in Korea included Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis (larva), Trichostrongylus sp. (larva), Paracapillaria philippinensis (syn. Capillaria philippinensis), Enterobius vermicularis, Fasciola hepatica, dicrocoeliids, Paragonimus westermani, Clonorchis sinensis, Metagonimus yokogawai, Pygidiopsis summa, Gymnophalloides seoi, Isthmiophora hortensis, Dibothriocephalus nihonkaiensis (syn. Diphyllobothrium nihonkaiense), and Taenia spp. tapeworms. The findings obtained by Korean paleoparasitologists/archaeologists have brought about deep insight into the status of helminthic infections in Korea’s past populations. Continued paleoparasitological research is essential for further understanding of ancient parasites and parasitic diseases in Korea. [ABSTRACT FROM AUTHOR]

The identification of a calcified hydatid cyst in the bioarcheological record is key to the diagnosis of cystic echinococcosis (i.e., hydatid disease), a parasitic infection caused by the tapeworm Echinococcus granulosus. This zoonosis can be linked to human–canid interactions, given the reproductive cycle of the parasite (from canids to herbivores/humans as intermediate hosts), and it is commonly associated with agropastoral communities in both the past and present. However, it is not easy to identify a calcified hydatid cyst in the archeological record because of preservation problems and its similarity with other calcifications of biological and geological origin. We report the presence of two fragmented ovoidal calcified formations associated with human remains in different medieval Islamic cemeteries from the Kingdom of Granada in al‐Andalus (Southern Iberia, 13th–15th centuries AD). These formations were analyzed by scanning electron microscopy and energy‐dispersive X‐ray spectroscopy. The localization, morphology, and composition of the calcifications indicate that they are hydatid cysts caused by E. granulosus, representing the first evidence of cystic echinococcosis in Islamic Medieval Europe. Our results are in line with archeological and historical records of human–animal interactions and agropastoral practices in al‐Andalus, and they highlight the importance of analyzing calcified masses in the osteoarcheological record.

The aims of the present study were: (1) to examine the parasite fauna found in carnivore coprolites from Cueva Huenul 1 archaeological site, located in northern Patagonia (Neuquén Province, Argentina), (2) to evaluate the role of this carnivores in the cycle of zoonotic parasites in the past, (3) to discuss the possible effect of the infections in humans that inhabit the cave during the Quaternary, and (4) to evaluate possible differences in egg measurements among layers. Several coprolites were obtained from layers dated since the Pleistocene-Holocene Transition. Faeces were whole processed, rehydrated, homogenised, and examined via light microscopy. Eggs of parasites were measured and photographed. Coprolites were assigned to a small feline. A total of 11 parasite species were found (8 nematode, 2 trematode, and 1 coccidian species). The paleoparasitological findings of this study display a great richness of parasitic species present in felines from CH1 through the Pleistocene-Holocene transition, some of them zoonotic. Early human societies that discontinuously occupied the site during the time scale studied could have been exposed to these infections. [ABSTRACT FROM AUTHOR]

To evaluate the presence of Dicrocoelium sp. in a child from a Late Antique funerary context from Cantabrian Spain and discuss whether the infection is true infection or pseudoparasitosis. Four skeletons, including one from a 5–7 year old child, have been analysed from the archaeological site of El Conventón, dated between the sixth and seventh centuries AD. The paleoparasitological study was conducted through the analysis of soil samples from different parts of the skeleton and funerary context using the rehydration, homogenization, and micro-sieving method, and visualized through brightfield microscopy. A soil sample from the pelvic region tested positive for Dicrocoelium sp. (possibly D. dendriticum). The child was infected with Dicrocoelium dendriticum, which based on archaeological and historical contexts may be related to hygiene or dietary behaviour. We present one of the few cases of the identification of a Dicrocoelidae parasite directly associated with a human skeleton that provides historical knowledge of a zoonotic disease. The diagnosis of a zoonosis through the identification of ancient parasites is complex. In addition, Dicrocoelium sp. in association with skeletal human remains is rare due to the potential low prevalence of this parasite. Highlight the importance of paleoparasitological analysis to link parasitic infection diseases with socioeconomic issues by using funerary contexts with skeletal remains.

To characterize patterns in the taxonomic diversity of parasites infecting the population of Aalst, Belgium, between the 12th and 17th centuries. 14 sediment samples from seven cesspits dated 1100–1700 CE. Digital light microscopy and Enzyme-linked immunosorbent assay (ELISA). We identified eggs of four species of helminths: whipworm (Trichuris trichiura), roundworm (Ascaris lumbricoides), Echinostoma fluke and Dicrocoelium fluke. ELISA results for protozoal parasites were negative. Taxonomic diversity of parasite infections remained constant from the 12th to the 17th centuries. Roundworm and whipworm, spread by poor sanitation, were dominant. Two species of zoonotic parasites were also identified, including for the first time ever in the Low Countries the Echinostoma fluke, which may have been spread by eating uncooked freshwater animal foods. Analysis of sediment samples spanning such a broad chronology (six centuries) from a single city offers the opportunity to track diachronic change, which is rare in paleoparasitological studies. We were unable to acquire samples from cesspits dating to the 14th century. Additional data from other Low Countries towns may strengthen the patterns identified in this paper. A similar approach can be used to investigate towns in different regions of the world. [ABSTRACT FROM AUTHOR]

Paleoparasitological investigation in the archeological site of the Caspian Sea littoral revealed the presence of human Dioctophyma renale infection, a ubiquitous kidney-residing helminth of mammals, during the Parthian Empire of Iran (247 BC–224 AD). This study reports the oldest human infection with giant kidney worm in the Middle East, mainly in an area where the infection is reported nowadays. The paucity of records throughout the literature suggests that the same species of parasite occurred with low frequency in the past, as well. The cemetery in the archeological site of Kiasar represented a unique opportunity of studying human and animal parasites of the Parthian Empire in Iran. [ABSTRACT FROM AUTHOR]

Parasites have affected and coevolved with humans and animals throughout history. Evidence of ancient parasitic infections, particularly, reside in archeological remains originating from different sources dating to various periods of times. The study of ancient parasites preserved in archaeological remains is known as paleoparasitology, and it initially intended to interpret migration, evolution, and dispersion patterns of ancient parasites, along with their hosts. Recently, paleoparasitology has been used to better understand dietary habits and lifestyles of ancient human societies. Paleoparasitology is increasingly being recognized as an interdisciplinary field within paleopathology that integrates areas such as palynology, archaeobotany, and zooarchaeology. Paleoparasitology also incorporates techniques such as microscopy, immunoassays, PCR, targeted sequencing, and more recently, high-throughput sequencing or shotgun metagenomics to understand ancient parasitic infections and thus interpret migration and evolution patterns, as well as dietary habits and lifestyles. The present review covers the original theories developed in the field of paleoparasitology, as well as the biology of some parasites identified in pre-Columbian cultures. Conclusions, as well as assumptions made during the discovery of the parasites in ancient samples, and how their identification may aid in better understanding part of human history, ancient diet, and lifestyles are discussed.

South American camelids (SAC) played a central biocultural role in Andean communities until today. Paleoparasitology, a discipline examining parasite remains from ancient times, can shed light on SAC, animals closely related to humans, providing insights into camelid populations, societies and the environment in the past. The objectives of this study are (1) to provide new insight into the parasite diversity of SAC from the Southern Puna, (2) to compare parasite diversity between different sites, and (3) to interpret the findings in relation to environmental and cultural changes in the Puna over time. The coprolites studied proceed from three archaeological sites in the Southern Puna: Cueva Inca Viejo (CIV), Punta de la Peña 4 (PP4) and Piedra Horadada 2 (PH2). A total of 153 coprolites were studied, subjected to rehydration, homogenization, filtration and spontaneous sedimentation. The assignation of the zoological origin of coprolites as SAC was based on their morphology, biogeographic origin, the presence of Eimeria macusaniensis and Lamanema chavezi/Nematodirus lamae and aDNA analysis. Seventeen parasite taxa belonging to Apicomplexa, Nematoda and Platyhelminthes were found, representing the highest richness recorded in ancient times until now. A noteworthy finding was the recovery of zoonotic species like Fasciola hepatica and capillariids, providing insight into possible zoonotic infections in ancient Andean populations. The record of Moniezia sp. and Strongyloides sp. suggest their presence in native Andean species before the arrival of Hispanic societies. The results revealed a parasitic fauna consistent with both modern and paleoparasitological studies. Variations in the composition of parasite assemblages were observed over time and between sites.

Parasites are the causative agents of infectious diseases that have affected humans throughout our evolution. Some appear to have been ubiquitous in past societies around the globe, but others were only viable in distinct regions where the conditions suited their complex life cycles. This review considers how we can recover and identify ancient parasites, before interrogating the literature to explore some of the ways this evidence can help us to better understand past societies. Variability in sanitation infrastructure, diet, cooking methods, lifestyle, behaviour and environment all affected the kinds of parasites that could infect past people, and determined how common infection was. The health consequences of parasite infection in different past communities are considered, as we think about the many ways health can be impaired by such infections. Where a good number of studies have focussed on one geographic region, variation in the apparent endemic range of certain parasite species allows an assessment of the relationship between humans and the surrounding environment. When parasites are found outside of their usual range this can be used as a marker of long distance travel and migrations. As the body of evidence for parasites in past populations expands, so do the ways we can use this information in an innovative manner to better understand those who lived in the past. • Parasites can be detected in archaeological contexts. • Their presence indicate diet and efficacy of sanitation technologies. • Many impact the health of past populations. • When found outside their endemic range can indicate migrations and trade.

To investigate how lifestyle may have impacted the risk of contracting intestinal parasites in medieval England. Regular clergy (such as those living in monasteries) and the lay population form interesting groups for comparison as diet and lifestyle varied significantly. Monasteries were built with latrine blocks and hand washing facilities, unlike houses of the poor. Sediment samples from the pelvis, along with control samples from feet and skull, of 19 burials of Augustinian Friars (13th-16th century), and 25 burials from All Saints by the Castle parish cemetery (10th-14th century), Cambridge. We analysed the sediment using micro-sieving and digital light microscopy to identify the eggs of intestinal parasites. Parasite prevalence (roundworm and whipworm) in the Augustinian friars was 58%, and in the All Saints by the Castle parishioners just 32% (Barnards Test score statistic 1.7176, p-value 0.092). It is interesting that the friars had nearly double the infection rate of parasites spread by poor hygiene, compared with the general population. We consider options that might explain this difference, and discuss descriptions and treatment of intestinal worms in medical texts circulating in Cambridge during the medieval period. This is the first study to compare prevalence of parasite infection between groups with different socioeconomic status from the same location. Quality of egg preservation was suboptimal, so our data may under-represent the true prevalence. Larger studies with greater statistical power, covering different time periods and regions.

Coprolites are one of the sources of evidence most commonly used in paleoparasitological studies. However, the zoological origin identification is not always possible. Parasites of the genus Eimeria (Apicomplexa: Eimeriidae) are obligate protozoan which have evolved to exhibit a great diversity of host range, and present strict host specificity. Usually, the identification of Eimeria spp. can be done by morphological characteristics such as size and shape of the oocysts. Moreover, molecular diagnostic methods such as PCR have proven to be very useful methodologies for an accurate taxonomic identification. In recent years, molecular techniques have started to be applied in paleoparasitological studies. Here, we provide the first integrative approach that combine light microscopic studies and ancient DNA (aDNA) in order to detect and identify Eimeria spp. on artiodactyl coprolites recovered from an archeological context from northwestern Patagonia, Argentina. The main objective is to discuss the advantages of complementing these two approaches as a promising tool to identify the zoological origin of coprolites. Furthermore, we provide paleoparasitological data about the presence of Eimeria spp. in coprolites of South American ungulates. Light microscopic studies allowed the identification of oocysts attributed to Eimeria spp. in 13 of the 40 coprolites. Amplification and sequencing of the aDNA ITS1 detected the presence of Eimeria spp. in 5 of the 10 samples, and allowed the taxonomic identification of these sequences as belonging to Eimeria arloingi. Furthermore, the results obtained from cytochrome b gene (Cytb) analysis confirmed the identity of the host as Capra hircus. Results displayed the presence of coccidiosis in goats from historical times. This study highlights that both techniques are complementary and promotes the use of the identification of Eimeria spp. in ancient samples in order to identify the zoological origin.

Paleoparasitological studies have made important contributions to our understanding of the past epidemiology of parasites, infection in past populations and lifestyle in the past. In some cases, these ancient parasites can also provide evidence for long distance travel or migration of people in the past. Three sediment samples from a 15th–16th c. CE latrine from the Spanish nation house in Bruges, Belgium were analysed for preserved helminth eggs using microscopy. Bruges was a major trading centre in medieval Europe, thus it was home to a large merchant population with extensive trading networks. Paleoparasitological analysis revealed a preserved parasite egg from Schistosoma mansoni , which causes intestinal schistosomiasis. Roundworm, whipworm, liver fluke and Taenia tapeworm eggs were also found in the latrine which is consistent with parasites previously found in the local population in the medieval period. These new data provide direct evidence for the movement of S. mansoni outside of its endemic area. Today the vast majority of S. mansoni infections occur in Sub-Saharan Africa, with additional endemic areas in the Arabian peninsula and South America. The introduction of S. mansoni into South America is proposed to have occurred relatively recently in human history, as the result of forced movement of people from Africa to the Americas with the Atlantic slave trade. Thus, this infection may have occurred in a merchant who acquired the parasite during trade voyages to Africa or in an individual living in Africa who migrated to Bruges.

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.

This study aims to (i) analyse whether speleothems may contain fossil parasitic worm eggs and, if so, (ii) identify the pathogens involved, and (iii) place them in geological, palaeontological, and chronological contexts to know the zoonoses that could affect human and animal populations during the Middle Pleistocene. A sample of calcite dated to the beginning of MIS 9 and MIS 8 from the Bàsura cave (Liguria, Italy) was analysed. The chemical protocol applied is characterised using hydrochloric acid, the reduction of hydrofluoric acid application time, and by the absence of the use of base, dense liquor or acetolysis. An embryophore of a taeniid was recovered. Endoparasitic worm eggs can be found in speleothems. A taeniid embryophore was found in a calcite level dated to MIS 9. Zoonoses related to the Taeniidae family existed 300,000 years ago in the northern Mediterranean region and may have affected Middle Pleistocene predators, carnivores, or humans. Speleothems are good tools for paleoparasitological studies. This is the oldest taeniid recovered and identified. A more precise determination of the genus of this taeniid is not possible in the absence of more precise palaeontological data. An application of this approach to other Pleistocene speleothems could broaden the spectrum of parasites and their zoonoses over remote Pleistocene periods. [ABSTRACT FROM AUTHOR]

Nowadays, wildlife is one of the most important sources of zoonoses, and it is a major concern for public health. Nevertheless, little is known about the role of wildlife as a reservoir and source of infectious diseases in the past. South America presents a wide diversity of wildlife. In the south of the continent, Argentina shelters a large diversity of neotropical carnivores. Although the paleoparasitological studies on carnivores have been increasing in southern Argentina, most of the efforts have been focused in a handful of sites located in western Patagonia. In this paper, two coprolites of felid found in Cueva Galpón, an initial late Holocene mortuary site from northeast Patagonia (Argentina), were studied for paleoparasitological purposes. Samples were processed by rehydration and homogenization, filtered and processed by spontaneous sedimentation. The samples were assigned to Puma concolor (puma) or Panthera onca (jaguar). Microscopic observations revealed that both coprolites were positive for parasite remains. High parasite richness was observed. Six nematodes, one cestode, and one coccidian morphotypes were reported. This is the first time that Gnathostoma sp. and Spirocerca sp. were recovered from holocenic times from Patagonia. This finding implies that some diseases such as taeniasis, spirocercosis, gnathostomosis, ascariasis, and coccidiosis could be present in holocenic wildlife from Patagonia prior to the Spanish colonization and domestic animal introduction. The overall results suggest that felids could have played a role as reservoirs and source of some parasitic species, some of which are zoonotic. Therefore, this animal could have entailed a risk agent for human health in the site. [ABSTRACT FROM AUTHOR]

Parasites are useful pathogens to explore human–animal interactions because they have diverse life cycles that often rely on both as hosts. Moreover, some species are not host specific and are transmitted between animals and humans. Today most emerging infections are zoonoses. Here, we take a specific look at the emergence and re‐emergence of zoonotic parasites throughout hominin evolution and consider evolutionary, cultural, and ecological factors involved in this. We combine genetic studies focused on molecular phylogenetic reconstructions, most often using the ribosomal RNA gene unit and mitochondrial genes from modern parasites, archaeological evidence in the form of preserved parasite eggs and antigens in skeletal and mummified remains, and modern epidemiological data to explore parasite infections throughout hominin evolution. We point out the considerably ancient origins of some key zoonotic parasites and their long coevolutionary history with humans and discuss factors contributing to the presence of many zoonotic parasites in the past and today including dietary preferences, urbanization, waste disposal, and the population density of both humans and domesticated animals.

Sambaquis or shellmounds are archeological sites constructed by hunter-fisher-gatherers that inhabited the Brazilian coast about 10,000–2000 yrs BP. Jabuticabeira II (JABII: 2890 ± 55 to 1805 ± 65 BP) is one of dozens of contemporaneous sambaquis of the Santa Catarina state, South Brazil, and contains hundreds of neatly organized burials, indicating great population density. In order to gather information about the health, diet and way of life of people in JABII, a paleoparasitological, paleogenetic, and micro-human remains investigation was carried out. Pelvic region and environmental control samples from six individuals exhumed from JABII were submitted to microscopic and ancient DNA (aDNA) investigation. Paleoparasitological analyses based on light microscopy were negative. However, a variety of informative microremains were found. Diatoms, fish scales, and algae characterize the marine and estuarine environment. Ipomoea batatas and Zea mays starch grains suggested cultivated items as part of their diet in agreement with the literature. The finding of Podocarpus sp. pollen grain, characteristic of highlander vegetation, suggests human mobility of JABII individuals which were settlement in the coast. Paleogenetic analyses showed Ascaris sp. helminth infection based on nad 1 gene fragment detected from an individual excavated at L3 FS7 burial (1826 ± 40 BP). This aDNA result places the antiquity of Ascaris sp. infection, and haplotypes that are circulating in humans and other animals nowadays, in Pre-Columbian South American times.

Growing evidence suggests that biodiversity mediates parasite prevalence. We have compiled the first global database on occurrences and prevalence of marine parasitism throughout the Phanerozoic and assess the relationship with biodiversity to test if there is support for amplification or dilution of parasitism at the macroevolutionary scale. Median prevalence values by era are 5% for the Paleozoic, 4% for the Mesozoic, and a significant increase to 10% for the Cenozoic. We calculated period-level shareholder quorum sub-sampled (SQS) estimates of mean sampled diversity, three-timer (3T) origination rates, and 3T extinction rates for the most abundant host clades in the Paleobiology Database to compare to both occurrences of parasitism and the more informative parasite prevalence values. Generalized linear models (GLMs) of parasite occurrences and SQS diversity measures support both the amplification (all taxa pooled, crinoids and blastoids, and molluscs) and dilution hypotheses (arthropods, cnidarians, and bivalves). GLMs of prevalence and SQS diversity measures support the amplification hypothesis (all taxa pooled and molluscs). Though likely scale-dependent, parasitism has increased through the Phanerozoic and clear patterns primarily support the amplification of parasitism with biodiversity in the history of life.

Despite the ubiquity of parasitism, the knowledge regarding fossil parasites remains fragmentary. As an example, South American clade Xenarthra was a predominant group of mammals during the Cenozoic; however, its paleoparasitological knowledge has many gaps, with only a few reports in armadillos and fewer in ground sloths. Darwin’s ground sloth (Mylodon darwini) was a mega mammal widely distributed in the Neotropics; however, its parasitic fauna is poorly known with the sole report of unidentified nematode eggs. Thus, this study aimed to determine additional host-parasite associations and to discuss its possible role as a reservoir of zoonotic parasites. Fifty-two coprolites from Cueva del Milodón Natural Monument were analyzed through coprological analysis to determine the presence of parasites. From these, 18 (34.62%) coprolites had parasitic helminth eggs belonging to 6 taxa: Calodium sp., Ascaridida, Hymenolepididae, Anoplocephalidae, Taeniidae, and Digenea. All these findings are new records for this sloth; also, two of them, Calodium sp. and Anoplocephalidae, have represented a risk for the health of ancient humans. Eggs of Calodium were similar to those previously isolated from ancient humans in Patagonia. Thus, Darwin’s ground sloth has represented a potential reservoir of zoonotic helminths, which is interesting considering this species was in close contact with humans in ancient Patagonia. Thus, additional collaboration with paleontologists is highlighted considering the incipient development of paleoparasitology in Chile, which could elucidate the presence of important pathogens, contributing to a better understanding of the evolution and changes in the distribution and virulence of certain parasites through time.

South American camelids (SAC) have occupied a central role in the development of Andean societies. They are widely distributed in South America and since ancient times are an important factor in Andean economies and social and ritual life. The archaeological site Punta de Peña 4 (PP4) is located in Antofagasta de la Sierra Basin (Southern Puna of Argentina). PP4 is a rock overhang and presents a large occupational sequence (early Holocene until historic times). The aim of this contribution is to study parasite diversity and the relationship among parasites and SAC through holocenic times in the Southern Puna of Argentina. Besides, differences in parasite egg preservation in the site were discussed. A total of 65 coprolites assigned to SAC were rehydratated, homogenized, filtered, allowed to spontaneous sedimentation and examined for parasite remains. Given the morphology of the coprolites, the biogeographic origin and the presence of coccidian oocysts of Eimeria macusaniensis in some of them, a camelid origin of the coprolites is suggested. This is the first paleoparasitological study from PP4, an archaeological site of Antofagasta de la Sierra, a key region in northwestern Argentina and Central Andes. Eleven taxa of parasites were found belonging to Apicomplexa, Platyhelminthes, and Nematoda. Specific parasite species of SAC were found, such as E. macusaniensis and Lamanema chavezi/Nematodirus lamae. A remarkable finding was the presence of Moniezia sp. and Strongyloides sp. in coprolites from different levels of PP4, pointing out the presence of these genera in native artiodactyls of the region previous to the arrival of Hispanic societies. Results displayed a change in the number of parasite taxa present in SAC through time. The parasite-SAC relation through time and differences in parasite egg preservation between levels and sectors (covered and uncovered) of the site are discussed. [ABSTRACT FROM AUTHOR]

Although research conducted in East Asia has uncovered parasite eggs from ancient toilets or cesspits, data accumulated to date needs to be supplemented by more archaeoparasitological studies. We examined a total of 21 soil samples from a toilet-like structure at the Hwajisan site, a Baekje-period royal villa, in present-day Korea. At least 4 species of helminth eggs, i.e., Trichuris trichiura, Ascaris lumbricoides, Clonorchis sinensis, and Trichuris sp. (or Trichuris vulpis) were detected in 3 sediment samples of the structure that was likely a toilet used by Baekje nobles. The eggs of T. trichiura were found in all 3 samples (no. 1, 4, and 5); and A. lumbricoides eggs were detected in 2 samples (no. 4 and 5). C. sinensis and T. vulpis-like eggs were found in no. 5 sample. From the findings of this study, we can suppose that the soil-transmitted helminths were prevalent in ancient Korean people, including the nobles of Baekje Kingdom during the 5th to 7th century.

Abstract A paleoparasitological analysis was carried out on a large coprolite assigned to a carnivoran mammal, recovered from the Municipality of Uruguaiana, in the western region of the State of Rio Grande do Sul, Brazil, where the Upper Pleistocene Touro Passo Formation crops out. For this, an individual sample was extracted from the specimen using an electric drill, dissociated with 10% hydrochloric acid solution, washed with distilled water, and sifted through a 500 mesh Tyler sieve. After laboratory processing, the sediment retained on the sieve was mixed with glycerin and examined by optical microscopy, which revealed the presence of 14 protozoan oocysts and three nematode eggs. The morphological characteristics of the oocysts (i.e., spherical shape, thick-walled, internal zygote apparently at the beginning of sporulation, as well as their size) and of the eggs (i.e., ovoidal shape, rounded ends, smooth surface, thin-shelled, embryo in their interior, along with their morphometry) suggest that these specimens belong respectively to the orders Eucoccidiorida and Strongylida (Family Ancylostomatidae) represented by several parasitic species of the alimentary tract of modern carnivore. This is the first record of paleoparasites discovered in a vertebrate host from the Touro Passo Formation.

Paleoparasitology is a discipline of bioarchaeology that studies human and animal parasites and their evolution through time. It is at the frontier between biological sciences and the humanities, and aims to provide valuable clues about the lifestyles of former populations. Through examples chosen among recent case studies, we show in this review how paleoparasitology contributes to issues related to food, health, hygiene, organic waste management, and site occupation by ancient populations, but also, in the longer term, to questions of the evolution of the human/animal relationship and the history of diseases. This article provides an overview of this research field, its history, its concepts, and in particular, its applications in archaeology and the history of diseases. [ABSTRACT FROM AUTHOR]

Parasitism is inherent to life and observed in all species. Extinct animals have been studied to understand what they looked like, where and how they lived, what they fed on, and the reasons they became extinct. Paleoparasitology helps to clarify these questions based on the study of the parasites and microorganisms that infected those animals, using as a source material coprolites, fossils in rock, tissue, bone, mummy, and amber, analyses of ancient DNA, immunodiagnosis, and microscopy.

In the southern cone of South America, inhabit a large diversity of Neotropical carnivores. Carnivore coprolites are a valuable source of paleoecological and paleoparasitological information. The rock shelter Gruta del Indio (GI) is an emblematic archeological and paleontological site located from Mendoza, Argentina. Several studies were conducted at this site, which provided a stratified sequence spanning the last ∼31 ky BP. The aim of this work was to study parasite remains found in coprolites assigned to carnivores from GI, with the purpose of contributing to the paleoecological knowledge of the site. Twenty coprolites were examined for parasites. Samples were rehydrated in a 0.5% water solution of trisodium phosphate, then homogenized, filtered, and processed by spontaneous sedimentation. The macroscopic remains were separated and dried at room temperature and were examined for diet analysis. All micromammal prey belonged to the Order Rodentia, and six histricomorphs could be identified. Also, bird bones, plant, arthropod, and hair remains were found. Five coprolites contained parasite remains, and eight nematode species were recovered. This is the first paleoparasitological study at this site, and the findings broaden the knowledge of the biogeographic history of the gastrointestinal helminths found. The obtained results evidence the importance of carnivore coprolite studies recovered from archeological contexts in the reconstruction of paleoecological scenarios. Also, the importance of carnivores for the dispersion of their own parasites and the parasites of their prey are discussed. These parasitological findings contribute with the study of the presence of potential parasitic zoonoses in the Holocene. [ABSTRACT FROM AUTHOR]

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.

Sloths and ground sloths (Xenarthra: Tardigrada) are among the most conspicuous mammals in the Cenozoic faunas of South America. During the late Pleistocene and the early Holocene, all the megafaunal xenarthrans became extinct. While much attention has been paid to understanding the causes of megafauna extinction, less attention has been given to understanding the impacts of the loss of the megafauna on other organisms with whom they interacted. Paleoparasitology offers the opportunity to look back into the past and observe directly how parasites responded to environmental change and host decline events. The present work is the first paleoparasitological study on megaherbivores dung from the archaeological site Cueva Huenul 1 (northwestern Patagonia, Argentina). Twenty one dung samples were examined for parasites. Samples were processed by rehydration in a 0.5% water solution of trissodium phosphate, followed by homogenization, filtered and processed by spontaneous sedimentation. Additionally, microhistological analyses of three samples were made. The dung samples were identified as belonging to a ground sloth. Ground sloths from northwestern Patagonia were infected by the nematodes Trichostrongylus sp., Nematodirus sp., at least three Strongylida-type species, Trichuris sp., one ascaridid and one unidentified nematode. Also, the results indicated that the diet was mainly based on shrub species (Schinus johnstonii , Prosopis sp., Berberis empetrifolia , Ephedra chilense and Retanilla patagonica), typical of the Monte vegetation. Also, the cacti Maihuenia and the grasses Festuca kurtziana , Hordeum comosum , Stipa speciosa and Poa sp. (Family Poaceae) were found but in less frequency. The host-parasite-environment interactions, the potential parasitic diseases and ecological consequences of the ground sloth extinction are discussed. This study shows the potential of paleoparasitological studies of ancient feces to contribute to the understanding of the evolutionary histories of parasites and hosts. [ABSTRACT FROM AUTHOR]

To differentially diagnose a calcified formation recovered from a 13th century AD grave from the Tuscan monastery of Badia Pozzeveri, Lucca, Italy. A calcified formation from the thoraco-abdominal region of a skeleton buried in the monastery cemetery. Cone Beam Computed Tomography, Scanning Electron Microscope and Energy Dispersive X-Ray Spectroscopy. A hollow, calcified ovoid formation was identified as typical of a hydatid cyst, permitting the diagnosis of cystic echinococcosis in a 35-45year-old female. The study reveals the circulation of the parasite Echinococcus granulosus in the region of Lucca in late medieval Tuscany. This finding is the fourth case of cystic echinococcosis from an archaeological context in Italy and provides insight into environmental conditions that appear to have affected members of a community, irrespective of social status. Caution and the application of multiple analyses must be exercised in the differential diagnosis to discriminate among calcified formations. Analysis of stable isotopes of the calcified formation, such as 15N and 13C, in order to compare them with isotopic values of the host individual and to further confirm the parasitic origin of the find.

This study was designed to search for ancient parasites in abdominal content and coprolites from Bolivian mummies. Twelve mummified individuals from the Andean highlands, housed at the National Museum of Archaeology (MUNARQ) in La Paz, Bolivia. Microscopic analysis of rehydrated samples (coprolites and abdominal content), following Lutz's spontaneous sedimentation technique. Eggs of Enterobius vermicularis were identified in coprolites from one mummy, and capillariid eggs in the organic abdominal content from another individual. This is the first evidence of ancient intestinal parasites in Bolivian mummies. This pioneering study focused on the search of ancient intestinal parasites in human remains of the Bolivian Andes and contributes to greater knowledge of paleoparasitology in South America. All mummies in the MUNARQ belonged to the Andean Bolivian highlands (post-Tiwanaku era or Late Intermediate Period), although the exact provenance of the material and the associated contexts are not well recorded. Considering the great number of well-known archaeological sites and other unexplored sites in Bolivia, in addition to large collections in museums, further paleopathological and paleoparasitological molecular studies in mummies and skeletons are called for.

Paleoparasitological analysis was carried on 4 Merovingian skeletons, dated from the late-5th to the late-9th centuries, and recovered in the church of Saint-Martin-au-Val in Chartres (Center region, France). The corpses were buried in stone sarcophagi, which were still sealed at the time of excavation. Parasite marker extraction was conducted on sediment samples taken from the abdominal and pelvic regions, but also on samples taken from under the head and the feet as control samples. Microscopic observation revealed the presence of 3 gastrointestinal parasites, namely the roundworm (Ascaris lumbricoides), the whipworm (Trichuris trichiura) and the fish tapeworm (genus Diphyllobothrium). This analysis contributes to a better knowledge of the health status and the lifestyle of ancient medieval populations during the Merovingian period, for which very few paleoparasitological data were available, up until now. It demonstrates the presence of the fish tapeworm for the first time during this period. [ABSTRACT FROM AUTHOR]

As we learn more about parasites in ancient civilizations, data becomes available that can be used to see how infection may change over time. The aim of this study is to assess how common certain intestinal parasites were in China and Korea in the past 2000 years, and make comparisons with prevalence data from the 20th century. This allows us to go on to investigate how and why changes in parasite prevalence may have occurred at different times. Here we show that Chinese liver fluke (Clonorchis sinensis) dropped markedly in prevalence in both Korea and China earlier than did roundworm (Ascaris lumbricoides) and whipworm (Trichuris trichiura). We use historical evidence to determine why this was the case, exploring the role of developing sanitation infrastructure, changing use of human feces as crop fertilizer, development of chemical fertilizers, snail control programs, changing dietary preferences, and governmental public health campaigns during the 20th century.
