Second Pandemic Plague Genomes from Poland and Russia

Morozova, I. et al. New ancient Eastern European Yersinia pestis genomes illuminate the dispersal of plague in Europe. Philos. Trans. R. Soc. B 375:20190569 (2020) doi:10.1098/rstb.2019.0569

Abstract:

Yersinia pestis, the causative agent of plague, has been prevalent among humans for at least 5000 years, being accountable for several devastating epidemics in history, including the Black Death. Analyses of the genetic diversity of ancient strains of Y. pestis have shed light on the mechanisms of evolution and the spread of plague in Europe. However, many questions regarding the origins of the pathogen and its long persistence in Europe are still unresolved, especially during the late medieval time period. To address this, we present four newly assembled Y. pestis genomes from Eastern Europe(Poland and Southern Russia), dating from the fifteenth to eighteenth century AD. The analysis of polymorphisms in these genomes and their phylogenetic relationships with other ancient and modern Y. pestis strains may suggest several independent introductions of plague into Eastern Europe or its persistence in different reservoirs. Furthermore, with the reconstruction of a partial Y. pestis genome from rat skeletal remains found in a Polish ossuary, we were able to identify a potential animal reservoir in late medieval Europe. Overall, our results add new information concerning Y. pestis transmission and its evolutionary history in Eastern Europe.

Second Pandemic Plague Genomes From Riga

Susat, J. et al. Yersinia pestis strains from Latvia show depletion of the pla virulence gene at the end of the second plague pandemic. Scientific Reports 10:14628 (2020), doi:10.1038/s41598-020-71530-9

Abstract:

Ancient genomic studies have identified Yersinia pestis (Y. pestis) as the causative agent of the second plague pandemic (fourteenth–eighteenth century) that started with the Black Death (1,347–1,353). Most of the Y. pestis strains investigated from this pandemic have been isolated from western Europe, and not much is known about the diversity and microevolution of this bacterium in eastern European countries. In this study, we investigated human remains excavated from two cemeteries in Riga (Latvia). Historical evidence suggests that the burials were a consequence of plague outbreaks during the seventeenth century. DNA was extracted from teeth of 16 individuals and subjected to shotgun sequencing. Analysis of the metagenomic data revealed the presence of Y. pestis sequences in four remains, confirming that the buried individuals were victims of plague. In two samples, Y. pestis DNA coverage was sufficient for genome reconstruction. Subsequent phylogenetic analysis showed that the Riga strains fell within the diversity of the already known post‑Black Death genomes. Interestingly, the two Latvian isolates did not cluster together. Moreover, we detected a drop in coverage of the pPCP1 plasmid region containing the pla gene. Further analysis indicated the presence of two pPCP1 plasmids, one with and one without the pla gene region, and only one bacterial chromosome, indicating that the same bacterium carried two distinct pPCP1 plasmids. In addition, we found the same pattern in the majority of previously published post‑Black Death strains, but not in the Black Death strains. The pla gene is an important virulence factor for the infection of and transmission in humans. thus, the spread of pla‑depleted strains may, among other causes, have contributed to the disappearance of the second plague pandemic in eighteenth century Europe.

CfP EAA Barcelona 2018: Re‐thinking medieval and early modern pestilences from a biosocial perspective: advanced methods and renewed concepts in archaeological sciences

Deadline: 15 February 2018
Re‐thinking medieval and early modern pestilences from a biosocial perspective: advanced methods and renewed concepts in archaeological sciences

While contagious diseases have affected the human species since its origins, great medieval epidemics (e.g. plague, leprosy, tuberculosis) have sparked particular interest for decades. In recent years, archaeology has played an increasing role in the scientific study of medieval pestilences, notably by providing reliable data on both the paleobiology of epidemic victims and their burial treatment. Despite the various breakthroughs reached by interdisciplinary research, the study of past epidemics still needs to get improved, particularly through an integrated analysis of biological and social dimensions of these diseases, which are closely interrelated. We invite contributions regarding both recent methodological advances in the retrospective diagnosis of infectious diseases and the output of archaeological sciences on social and cultural factors acting in human populations’ adaptability to these diseases.

The session shall address various questions, among which:
– What are the new lines of research and future perspectives in paleopathological and palaeomicrobiological study of these diseases?
– What information paleobiological data derived from skeletal assemblages can provide on the epidemiological characteristics of the diseases?
– What was the endemicity of diseases in various places, how did they evolve over time, and how did various diseases competed each other?
– How funerary archaeology and textual sources contributes to reappraise the history of these diseases (e.g. attitudes towards the victims in terms of their integration and/or exclusion, depending on the time period and cultural framework)?
– Which methodological implementation would be desirable in the future to allow retrospective diagnosis of still poorly-known diseases (e.g. ergotism)?

Plague, an infectious disease caused by the bacterium Yersinia pestis, occurred in at least three major historical pandemics: the Justinianic Plague (6th to 8th century), the Black Death (1348-1352, with further epidemic outbreaks until the 18th century), and the Modern or Hong Kong Plague (19th to 20th century). However, it appears that the disease may be much older: DNA from Bronze Age human skeleton has recently shown that plague first emerged at least as early as 3000 BC. As any disease, plague has both a biological as well as a social dimension. Different disciplines can therefore explicate different aspects of plague which can lead to a better understanding of the disease and its medical and social implications.

The session was held on 2nd September 2016 as part of the 22nd Annual Meeting of the EAA with the aim of bringing together researchers from different disciplines who work on plague. It addressed a series of research questions, such as:

  • Which disciplines can contribute to the research on plague?
  • What are their methodological possibilities and the limitations of their methodologies?
  • How can different disciplines work together in order to gain a more realistic and detailed picture of plague in different periods and regions?
  • How did different societies react to plague? In which way may we prove or disprove evidence for such reactions – and which disciplines may contribute to the debate?
  • What where the common aspects, and what the differences of the various plague outbreaks? Are there any epidemiological characteristics that are essential and/or unique to plague?
  • What are possible implications of the pandemic spread and endemic occurrence of plague through the ages for the interpretation of historical and cultural phenomena?

Effects of 1342 rainfalls at the Neckar river, southwest Germany

Written, archaeological, and geographical sources show the heavy effects of the rainfalls in summer 1342. The mostly refer to the river Main, the middle Rhine, Elbe, and Weser.  A charter from the town of Esslingen situated at the river Neckar, dated 9th of September 1342 documents a court ruling. The local Augustinian monastery sued  against Kaisheim abbey, which owned a nearby vineyard. Soil was flooded into the Augustinian monastery. The document shows that the rainfalls in summer 1342 also affected the Neckar valley.
