A major 16th-Century Epidemic in Mexico Explained by Salmonella enterica genomes from victims

In Nature Ecology & Evolution (15 January 2018 issue) scientist identified Salmonella enterica as the potential cause of the epidemic known as ‘cocoliztli’ based on historical and archaeological evidence, to the 1545–1550 CE epidemic. Through the introduction of a new metagenomic analysis tool called MALT, applied in the study to search for traces of ancient pathogen DNA, they were able to identify Salmonella enterica in individuals buried in an early contact era epidemic cemetery. The scientists propose that S. Paratyphi C is a strong candidate for the epidemic population decline @ https://www.nature.com/articles/s41559-017-0446-6
