![Molecular detection of Yersinia pestis was achieved in the dental pulp of remains of humans excavated from one Justinian and two Black Death mass graves in France by spacer amplification and sequencing (+, positive polymerase chain reaction [PCR] amplification and sequencing; –, absence of PCR amplification; ND, not done). Sequence analyses showed strains were of Orientalis genotype in all sets of remains; one of them exhibited two mutations numbered according to Y. pestis CO92 strain genome seq](/eid/images/03-0933-F2.gif)
