Oldest reconstructed bacterial genomes link farming, herding with emergence of new disease

Using Salmonella enterica genomes recovered from human skeletons as old as 6,500 years, an international team of researchers illustrates the evolution of a human pathogen and provides the first ancient DNA evidence in support of the hypothesis that the cultural transition from foraging to farming facilitated the emergence of human-adapted pathogens that persist until today.
