Whole-genome sequencing and Phylogeographic analysis of Salmonella enterica serovar Napoli strains isolated from human cases occurred in Lombardy and Emilia-Romagna, Northern Italy

Salmonella enterica serovar Napoli (S. Napoli) is uncommon in Europe except in Italy,where it ranks among the top five serovars causing human infection. However, information about its epidemiology, ecology and virulence is poor, and no foodborne or environmental factor has been identified so far. In this project, forty-four S. Napoli strains isolated from human cases in Lombardy and Emilia- Romagna, Italy (2012-2014), were subjected to whole-genome sequencing (WGS) using the Illumina MiSeq platform.
