Genomic diversity of Salmonella Derby populations from animals to humans: study on source attribution and identification of specific host associations

In the European Union (EU), Salmonella enterica subsp. enterica serotype Derby (S. Derby) is the most abundant serotype isolated from pork meat. In France this pathogen is mainly isolated from pork and poultry meat and ranks since 2000 between the 5th and 8th position of the most frequently isolated serotypes in humans. Despite significant threat to human health, few studies have focused on the genetic diversity of this pathogen and all suffer from the low discriminatory power of the sub-typing method used or the lack of strains.
