We describe a Hib genome isolated from a 6-year-old Anglo-Saxon plague victim, from approximately 540 to 550 CE, Edix Hill, England, showing signs of invasive infection on its skeleton. We find that the genome clusters in phylogenetic division II with Hib strain NCTC8468, which also caused invasive disease. While the virulence profile of our genome was distinct, its genomic similarity to NCTC8468 points to mostly clonal evolution of the clade since the 6th century. We also reconstruct a partial Yersinia pestis genome, which is likely identical to a published first plague pandemic genome of Edix Hill.


The site of Edix Hill (Barrington, Cambridgeshire, UK) is an Anglo-Saxon cemetery dating between 500 and 650 CE. We sampled teeth from two individuals recovered from an unphased double burial (grave 85). The grave housed an adult male skeleton (25–35 years) (Sk 447A, EDI086/PSN625) with antemortem cranial trauma and a non-adult skeleton (6 years) (Sk 447B, EDI064/PSN604) showing non-pathognomonic signs of disease described below. They were excavated from a shallow grave, which seems to have been disturbed on multiple occasions leading to the recovery of partial skeletons. The deposition history of the grave could not be reconstructed based on site stratigraphy. However, the recovery of Y. pestis reads from both skeletons is suggestive of their contemporaneity. Radiocarbon dating of individual EDI064 (416-541 calAD) further supports an association with the first wave of the Justinianic plague 541–544 CE.
