Sumario:BACKGROUND: Historical records suggest that multiple burial sites from the 14th–16(th) centuries in Venice, Italy, were used during the Black Death and subsequent plague epidemics. METHODOLOGY/PRINCIPAL FINDINGS: High throughput, multiplexed real-time PCR detected DNA of seven highly transmissible pathogens in 173 dental pulp specimens collected from 46 graves. Bartonella quintana DNA was identified in five (2.9%) samples, including three from the 16th century and two from the 15th century, and Yersinia pestis DNA was detected in three (1.7%) samples, including two from the 14th century and one from the 16th century. Partial glpD gene sequencing indicated that the detected Y. pestis was the Orientalis biotype. CONCLUSIONS: These data document for the first time successive plague epidemics in the medieval European city where quarantine was first instituted in the 14th century.
