    Abstract:
    A rapid diagnostic dipstick test (RDT) that detects Yersinia pestis F1 antigen has been recently applied on 18 putative plague victims exhumed from four archaeological burial sites in southeastern France dating back to the 16(th), 17(th) and 18(th) centuries. The Y. pestis antigen F1 was detected in 12 ancient samples out of 18 (67%). Negative controls confirmed their negativity (100%). Our results emphasize that the detection threshold of the RDT for plague (0.5 ng/ml) is sufficient for a first retrospective diagnosis of Y. pestis infection in ancient remains, and confirm the high specificity and sensitivity of the assay. Double-blind analyses performed by using two different techniques (RDT and 'suicide PCR') led us to the identification of the Y. pestis F1 antigen and the Y. pestis pla and gplD genes. These data provide clear evidence of the presence of Y. pestis in the examined specimens.
