(Feb. 18th, 2015) Italian Cemetery Holds Skeletons With Perfectly Preserved Cholera

An Italian church graveyard could preserve more than bodies: Researchers are searching the cemetery for the DNA of ancient strains of cholera. Cholera is a deadly diarrheal disease caused by a bacterium called Vibrio cholerae . In the 1850s, an epidemic swept the world. In 1854, during this epidemic, London doctor John Snow famously traced one outbreak to a contaminated water pump in the Soho district of the city. The case is still cited today as a triumph of epidemiology. Many victims of the 1850 outbreak rest in the church cemetery of Badia Pozzeveri, a village in the northern Italian province of Tuscany. In the yard of the San Pietro a Pozzeveri church, villagers hastily buried cholera victims and encased their bodies in lime. Ohio State University anthropologist Clark Spencer Larsen and his colleagues have been excavating this cholera graveyard for four years. They believe the villagers were trying to prevent the spread of the disease with the lime treatment. Inadvertently, however, they ended up preserving the bones of their loved ones - and potentially the DNA of the bacteria that killed them. "To our knowledge, these are the best preserved remains of cholera victims of this time period ever found," Larsen said in a statement . "We're very excited about what we may be able to learn." http://news.osu.edu/news/2015/02/15/an-italian-cemetery-may-provide-clues-on-cholera's-evolution/ FULL STORY
