Implications of the prevalence of Ascaris sp. in the funerary context of a Late Antique population (5th-7th c.) in Granada (Spain).

Objective: To evaluate the prevalence of gastro-intestinal parasites in human remains from Late Antiquity (5th - 7th c.) Granada (Spain).

Materials: 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).

Gastrointestinal parasite burden in 4th-5th c. CE Florence highlighted by microscopy and paleogenetics.

The study of ancient parasites, named paleoparasitology, traditionally focused on microscopic eggs disseminated in past environments and archaeological structures by humans and other animals infested by gastrointestinal parasites. Since the development of paleogenetics in the early 1980s, few paleoparasitological studies have been based on the ancient DNA (aDNA) of parasites, although such studies have clearly proven their utility and reliability. In this paper, we describe our integrative approach for the paleoparasitological study of an ancient population from Florence in Italy, dated to the 4th-5th c.

Multi-proxy analyses of a mid-15th century Middle Iron Age Bantu-speaker palaeo-faecal specimen elucidates the configuration of the 'ancestral' sub-Saharan African intestinal microbiome.

Background: The archaeological incidence of ancient human faecal material provides a rare opportunity to explore the taxonomic composition and metabolic capacity of the ancestral human intestinal microbiome (IM). Here, we report the results of the shotgun metagenomic analyses of an ancient South African palaeo-faecal specimen.

Methods: Following the recovery of a single desiccated palaeo-faecal specimen from Bushman Rock Shelter in Limpopo Province, South Africa, we applied a multi-proxy analytical protocol to the sample.

Paleoparasitology of Merovingian Corpses Buried in Stone Sarcophagi in the Saint-Martin-au-Val Church (Chartres, France).

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.

Assessing the Parasitic Burden in a Late Antique Florentine Emergency Burial Site.

Excavation (2008-2014) carried out under the Uffizi Gallery (Florence, Italy) led to the discovery of 75 individuals, mostly buried in multiple graves. Based on Roman minted coins, the graves were preliminarily dated between the second half of the 4th and the beginning of the 5th centuries CE. Taphonomy showed that this was an emergency burial site associated with a catastrophic event, possibly an epidemic of unknown etiology with high mortality rates.

Worldwide paleodistribution of capillariid parasites: Paleoparasitology, current status of phylogeny and taxonomic perspectives.

Introduction: Paleoparasitology, the study of parasites in the past, brings the knowledge of where and when they occurred in preterit populations. Some groups of parasites, as capillariids, have a complex and controversial systematic, hindering the paleoparasitological diagnosis. In this article, we synthesized the occurrence of capillariids in both the New and the Old World in ancient times, and discussed the difficulty of the diagnosis of species and the strategies for identification.

Palaeoparasitology and palaeogenetics: review and perspectives for the study of ancient human parasites.

While some species of parasites can be identified to species level from archaeological remains using microscopy (i.e. Enterobius vermicularis, Clonorchis sinensis), others can only be identified to family or genus level as different species produce eggs with similar morphology (i.

A First Case of Human Trichuriasis from a Roman Lead Coffin in France.

A paleoparasitological study was carried out on 2 lead coffins recovered from the Roman site of Jaunay-Clan (near Poitiers, France). For the first time, this particular type of burial gave positive parasitological results, and eggs of the whipworm were identified in 1 individual. In the present case, thanatomorphose associated with funerary practices may explain the scarcity of the recovered eggs.

Past Intestinal Parasites.

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.

Human Coprolites as a Source for Paleomicrobiology.

The paleomicrobiology of coprolites, which are fossilized fecal materials, has already yielded data about various organisms, including micro-eukaryotes, bacteria, and archaea, thus expanding our comprehension of ancient human dietary habits, gut microbiota, and intestinal and systemic infections. This mini-review briefly describes previous works and summarizes the main techniques used in handling coprolites and the findings obtained about ancient gut microbiota. Past intestinal and systemic infections are outlined.

Archaeological occurrences and historical review of the human amoeba, Entamoeba histolytica, over the past 6000years.

Understanding parasite history and the evolution of host/parasite relationships is one of the most important aspects of paleoparasitology. Within the framework of this research topic, this paper focuses on the human pathogenic amoeba, Entamoeba histolytica. The compilation of all the available archaeological data concerning this parasite leads to a first glimpse of the history of this parasite of current medical importance.

A New High-Throughput Approach to Genotype Ancient Human Gastrointestinal Parasites.

Human gastrointestinal parasites are good indicators for hygienic conditions and health status of past and present individuals and communities. While microscopic analysis of eggs in sediments of archeological sites often allows their taxonomic identification, this method is rarely effective at the species level, and requires both the survival of intact eggs and their proper identification. Genotyping via PCR-based approaches has the potential to achieve a precise species-level taxonomic determination.

The horse pinworm (Oxyuris equi) in archaeology during the Holocene: Review of past records and new data.

This paper focuses on the horse pinworm, Oxyuris equi, in archaeology during the Holocene period, and presents an overview of past published occurrences, early mentions in texts, and new data from our paleoparasitology research. This original compilation shows that the most ancient record of the horse pinworm dates to ca. 2500 years before present (ybp) in Central Asia and to ca.

Intestinal parasites in First World War German soldiers from "Kilianstollen", Carspach, France.

Paleoparasitological investigations revealed the presence of intestinal helminths in samples taken from the abdominal cavities of two German soldiers, recovered in the First World War site named "Kilianstollen" in Carspach, France. Eggs from roundworm, whipworm, tapeworm and capillariids were identified. The morphological and morphometrical comparison, followed by statistical analyses, showed that the Carspach capillariid eggs are similar to rodent parasites.

Polyphasic analysis of a middle ages coprolite microbiota, Belgium.

Paleomicrobiological investigations of a 14(th)-century coprolite found inside a barrel in Namur, Belgium were done using microscopy, a culture-dependent approach and metagenomics. Results were confirmed by ad hoc PCR--sequencing. Investigations yielded evidence for flora from ancient environment preserved inside the coprolite, indicated by microscopic observation of amoebal cysts, plant fibers, seeds, pollens and mold remains.

Viruses in a 14th-century coprolite.

Coprolites are fossilized fecal material that can reveal information about ancient intestinal and environmental microbiota. Viral metagenomics has allowed systematic characterization of viral diversity in environmental and human-associated specimens, but little is known about the viral diversity in fossil remains. Here, we analyzed the viral community of a 14th-century coprolite from a closed barrel in a Middle Ages site in Belgium using electron microscopy and metagenomics.

Testing new parasite egg extraction methods in paleoparasitology and an attempt at quantification.

In order to improve paleoparasitological analyses, we tested different acid (hydrochloric and hydrofluoric acids) and base (sodium hydroxide) combinations for parasite egg extraction in archaeological sediments. We used a method of egg counting to compare these results to those obtained with the standard paleo-parasitological RHM extraction protocol (rehydration-homogenization-micro-sieving). Tests show that the use of hydrochloric acid results in a concentration of some taxa like Ascaris sp.

Diphyllobothrium in the past: Review and new records.

This paper presents a paleoparasitological review of the fish tapeworm genus Diphyllobothrium. Comprehensive data from published articles and original results from the Reims paleoparasitology laboratory show that the fish tapeworm has co-evolved with humans for several thousand years, influenced by human dietary habits, cultural differences, and sometimes environmental changes. This taxon has been present in the Old World for at least 9500 years (early Neolithic period) and in the New World for 10,000 years.

Ancient dicrocoeliosis: Occurrence, distribution and migration.

This paper focuses on the lancet fluke, Dicrocoelium sp., and includes a complete review of the literature as well as numerous new research results. The compilation of all these data led to a global overview of ancient dicrocoeliosis history.

Identification of Taenia sp. in a mummy from a Christian Necropolis in El-Deir, Oasis of Kharga, ancient Egypt.

For the first time, a palaeoparasitological study was performed on 12 mummies from a Christian cemetery excavated in El-Deir, Oasis of Kharga, Egypt. The analysis revealed the presence of a tapeworm, probably Taenia sp., in a single individual.

New finding of Giardia intestinalis (Eukaryote, Metamonad) in Old World archaeological site using immunofluorescence and enzyme-linked immunosorbent assays.

In this study, nine organic sediment samples from a medieval archaeological site at Pineuilh, France, were examined for Giardia intestinalis using two commercially available immunological kits [enzyme-linked immuno sorbent and immunofluorescence (IFA) assays]. Both techniques detected G. intestinalis in one sample, dated to 1,000 Anno Domini.

Parasitism in Kansas in the 1800s: a glimpse to the past through the analysis of grave sediments from Meadowlark cemetery.

During the excavations of the XIX century Meadowlark cemetery (Manhattan, Kansas, US), samples of sediments were taken from around five skeletons, and analyzed to detect intestinal parasites. No helminth eggs were found, but immunological ELISA tests for Entamoeba histolytica were positive in three samples. The immunological techniques have been successfully used in paleoparasitology to detect protozoan infections.

Paleoparasitological remains revealed by seven historic contexts from "Place d'Armes", Namur, Belgium.

Human occupation for several centuries was recorded in the archaeological layers of "Place d'Armes", Namur, Belgium. Preventive archaeological excavations were carried out between 1996/1997 and seven historical strata were observed, from Gallo-Roman period up to Modern Times. Soil samples from cesspools, latrines, and structures-like were studied and revealed intestinal parasite eggs in the different archaeological contexts.

Diphyllobothrium: Neolithic parasite?

During paleoparasitological analyses on several Neolithic sites in Switzerland (Arbon-Bleiche 3) and southwestern Germany (Hornstaad-Hörnle I, Torwiesen II, and Seekirch-Stockwiesen), numerous eggs of Diphyllobothrium sp. were recovered. This is one of the earliest occurrences of this parasite during the prehistoric period in the Old World.
