The bacteria responsible for causing the 1348 Black Death, identified as one of the most cataclysmic events in human history, has been identified by researchers from Canada and Germany.
Using a novel method of DNA enrichment coupled with high-throughput DNA sequencing, Hendrik Poinar, an evolutionary geneticist from the McMaster University and Johannes Krause of the University of Tubingen have discovered that the now-extinct version of the Yersinia pestis bacterium initiated the bug that caused 30-50 million European deaths between 1347 and 1351. Never before have researchers understood the exact cause of the plague, which continues to claim some 2,000 deaths a year worldwide.
