Laboratório de Biologia Molecular de Parasitos, Departamento de Microbiologia e Parasitologia, Instituto Biomédico, Universidade Federal Fluminense, Niterói, Rio de Janeiro, 21041-210, Brazil.

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.

Functional diversity of microbial ecologies estimated from ancient human coprolites and dental calculus.

Philos Trans R Soc Lond B Biol Sci 2020 11 5;375(1812):20190586. Epub 2020 Oct 5.

Laboratories of Molecular Anthropology and Microbiome Research (LMAMR), University of Oklahoma, Norman, OK, USA.

Human microbiome studies are increasingly incorporating macroecological approaches, such as community assembly, network analysis and functional redundancy to more fully characterize the microbiome. Such analyses have not been applied to ancient human microbiomes, preventing insights into human microbiome evolution. We address this issue by analysing published ancient microbiome datasets: coprolites from Rio Zape ( = 7; 700 CE Mexico) and historic dental calculus ( = 44; 1770-1855 CE, UK), as well as two novel dental calculus datasets: Maya ( = 7; 170 BCE-885 CE, Belize) and Nuragic Sardinians ( = 11; 1400-850 BCE, Italy).

CoproID predicts the source of coprolites and paleofeces using microbiome composition and host DNA content.

PeerJ 2020 17;8:e9001. Epub 2020 Apr 17.

Department of Archaeogenetics, Max Planck Institute for the Science of Human History, Jena, Germany.

Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical distortions in archaeological sediments, making their source species difficult to identify on the basis of fecal morphology or microscopic features alone. Here we present a reproducible and scalable pipeline using both host and microbial DNA to infer the host source of fecal material. Read More

Genome data on the extinct Bison schoetensacki establish it as a sister species of the extant European bison (Bison bonasus).

BMC Evol Biol 2017 02 10;17(1):48. Epub 2017 Feb 10.

Institute for Integrative Biology of the Cell (I2BC), IBITECS, CEA, CNRS, Université Paris-Sud, Université Paris-Saclay, 91198, Gif-sur-Yvette cedex, France.

Background: The European bison (Bison bonasus), now found in Europe and the Caucasus, has been proposed to originate either from the extinct steppe/extant American bison lineage or from the extinct Bison schoetensacki lineage. Bison schoetensacki remains are documented in Eurasian Middle Pleistocene sites, but their presence in Upper Pleistocene sites has been questioned. Despite extensive genetic studies carried out on the steppe and European bison, no remains from the fossil record morphologically identified as Bison schoetensacki has been analyzed up to now.

Recovery of Toxoplasma gondii DNA in experimentally mummified skin and bones: Prospects for paleoparasitological studies to unveil the origin of toxoplasmosis.

Exp Parasitol 2016 Sep 10;168:51-5. Epub 2016 Jun 10.

Laboratory of Paleoparasitology, Escola Nacional de Saúde Pública/Fiocruz, Rio de Janeiro, RJ, Brazil.

Paleoparasitology studies parasite infections by finding the parasites' remains in preserved organic remains such as natural or artificial mummy tissues, skeletons, teeth, and coprolites, among others. However, some currently important infections like toxoplasmosis have not been studied by paleoparasitology. The reasons include this parasite's complex life cycle, the resulting difficulties in locating this protozoan in the intermediate host tissues, and the limitation of coprolite studies to felines, the protozoan's definitive host.

The Importance of Fossils in Understanding the Evolution of Parasites and Their Vectors.

Adv Parasitol 2015 18;90:1-51. Epub 2015 Aug 18.

Department of Life Sciences, Natural History Museum, London, UK.

Knowledge concerning the diversity of parasitism and its reach across our current understanding of the tree of life has benefitted considerably from novel molecular phylogenetic methods. However, the timing of events and the resolution of the nature of the intimate relationships between parasites and their hosts in deep time remain problematic. Despite its vagaries, the fossil record provides the only direct evidence of parasites and parasitism in the fossil record of extant and extinct lineages. Read More

Intrinsic challenges in ancient microbiome reconstruction using 16S rRNA gene amplification.

Sci Rep 2015 11 13;5:16498. Epub 2015 Nov 13.

Department of Anthropology, University of Oklahoma, Norman, OK, USA.

To date, characterization of ancient oral (dental calculus) and gut (coprolite) microbiota has been primarily accomplished through a metataxonomic approach involving targeted amplification of one or more variable regions in the 16S rRNA gene. Specifically, the V3 region (E. coli 341-534) of this gene has been suggested as an excellent candidate for ancient DNA amplification and microbial community reconstruction. Read More

Ancient mitochondrial DNA analyses of ascaris eggs discovered in coprolites from joseon tomb.

Korean J Parasitol 2015 Apr 22;53(2):237-42. Epub 2015 Apr 22.

Bioanthropology and Paleopathology Lab, Institute of Forensic Science, Seoul National University College of Medicine, Seoul 110-799, Korea.

Analysis of ancient DNA (aDNA) extracted from Ascaris is very important for understanding the phylogenetic lineage of the parasite species. When aDNAs obtained from a Joseon tomb (SN2-19-1) coprolite in which Ascaris eggs were identified were amplified with primers for cytochrome b (cyt b) and 18S small subunit ribosomal RNA (18S rRNA) gene, the outcome exhibited Ascaris specific amplicon bands. By cloning, sequencing, and analysis of the amplified DNA, we obtained information valuable for comprehending genetic lineage of Ascaris prevalent among pre-modern Joseon peoples. Read More

Ancient human microbiomes.

J Hum Evol 2015 Feb 3;79:125-36. Epub 2015 Jan 3.

Department of Anthropology, University of Oklahoma, 101 David L. Boren Blvd., Norman, OK 73019, USA. Electronic address:

Very recently, we discovered a vast new microbial self: the human microbiome. Our native microbiota interface with our biology and culture to influence our health, behavior, and quality of life, and yet we know very little about their origin, evolution, or ecology. With the advent of industrialization, globalization, and modern sanitation, it is intuitive that we have changed our relationship with microbes, but we have little information about the ancestral state of our microbiome, and we therefore lack a foundation for characterizing this change.

Paleomicrobiology: revealing fecal microbiomes of ancient indigenous cultures.

PLoS One 2014 10;9(9):e106833. Epub 2014 Sep 10.

Department of Biology, University of Puerto Rico, San Juan, Puerto Rico.

Coprolites are fossilized feces that can be used to provide information on the composition of the intestinal microbiota and, as we show, possibly on diet. We analyzed human coprolites from the Huecoid and Saladoid cultures from a settlement on Vieques Island, Puerto Rico. While more is known about the Saladoid culture, it is believed that both societies co-existed on this island approximately from 5 to 1170 AD. Read More

Resolving lost herbivore community structure using coprolites of four sympatric moa species (Aves: Dinornithiformes).

Proc Natl Acad Sci U S A 2013 Oct 30;110(42):16910-5. Epub 2013 Sep 30.

Landcare Research, Lincoln, Canterbury 7640, New Zealand.

Knowledge of extinct herbivore community structuring is essential for assessing the wider ecological impacts of Quaternary extinctions and determining appropriate taxon substitutes for rewilding. Here, we demonstrate the potential for coprolite studies to progress beyond single-species diet reconstructions to resolving community-level detail. The moa (Aves: Dinornithiformes) of New Zealand are an intensively studied group of nine extinct herbivore species, yet many details of their diets and community structuring remain unresolved.

Microbial communities in pre-columbian coprolites.

PLoS One 2013 5;8(6):e65191. Epub 2013 Jun 5.

Department of Biology, University of Puerto Rico, San Juan, Puerto Rico, United States of America.

The study of coprolites from earlier cultures represents a great opportunity to study an "unaltered" composition of the intestinal microbiota. To test this, pre-Columbian coprolites from two cultures, the Huecoid and Saladoid, were evaluated for the presence of DNA, proteins and lipids by cytochemical staining, human and/or dog-specific Bacteroides spp. by PCR, as well as bacteria, fungi and archaea using Terminal Restriction Fragment analyses.

A lost link between a flightless parrot and a parasitic plant and the potential role of coprolites in conservation paleobiology.

Conserv Biol 2012 Dec 1;26(6):1091-9. Epub 2012 Oct 1.

Landcare Research, P.O. Box 40, Lincoln, Canterbury 7640, New Zealand.

Late Quaternary extinctions and population fragmentations have severely disrupted animal-plant interactions globally. Detection of disrupted interactions often relies on anachronistic plant characteristics, such as spines in the absence of large herbivores or large fruit without dispersers. However, obvious anachronisms are relatively uncommon, and it can be difficult to prove a direct link between the anachronism and a particular faunal taxon. Read More

High-resolution coproecology: using coprolites to reconstruct the habits and habitats of New Zealand's extinct upland moa (Megalapteryx didinus).

PLoS One 2012 29;7(6):e40025. Epub 2012 Jun 29.

Landcare Research, Lincoln, Canterbury, New Zealand.

Knowledge about the diet and ecology of extinct herbivores has important implications for understanding the evolution of plant defence structures, establishing the influences of herbivory on past plant community structure and composition, and identifying pollination and seed dispersal syndromes. The flightless ratite moa (Aves: Dinornithiformes) were New Zealand's largest herbivores prior to their extinction soon after initial human settlement. Here we contribute to the knowledge of moa diet and ecology by reporting the results of a multidisciplinary study of 35 coprolites from a subalpine cave (Euphrates Cave) on the South Island of New Zealand.

Mylodon darwinii DNA sequences from ancient fecal hair shafts.

Ann Anat 2012 Jan 17;194(1):26-30. Epub 2011 May 17.

McMaster Ancient DNA Center, McMaster University, Hamilton, ON, Canada.

Preserved hair has been increasingly used as an ancient DNA source in high throughput sequencing endeavors, and it may actually offer several advantages compared to more traditional ancient DNA substrates like bone. However, cold environments have yielded the most informative ancient hair specimens, while its preservation, and thus utility, in temperate regions is not well documented. Coprolites could represent a previously underutilized preservation substrate for hairs, which, if present therein, represent macroscopic packages of specific cells that are relatively simple to separate, clean and process.

Molecular breeding of polymerases for resistance to environmental inhibitors.

Nucleic Acids Res 2011 Apr 4;39(8):e51. Epub 2011 Feb 4.

MRC Laboratory of Molecular Biology, Hills Road, Cambridge CB2 0QH, UK.

Potent inhibitors limit the use of PCR assays in a wide spectrum of specimens. Here, we describe the engineering of polymerases with a broad resistance to complex environmental inhibitors using molecular breeding of eight different polymerase orthologues from the genus Thermus and directed evolution by CSR in the presence of inhibitors. Selecting for resistance to the inhibitory effects of Neomylodon bone powder, we isolated 2D9, a chimeric polymerase comprising sequence elements derived from DNA polymerases from Thermus aquaticus, Thermus oshimai, Thermus thermophilus and Thermus brockianus.
