Genome-based summary of Salmonella enterica from African and American datasets, organized by continent, year of isolation, and serovar. Of the 6117 Salmonella enterica genomes that were successfully sequenced and that passed QC, 3100 (50.7%) were from Africa and 2313 (37.8%) were from America. Bubble size represents the number of genomes isolated between 1959 and 2017. The graphs represent the proportion of the main Salmonella serovars predicted based on genome analysis: 1844 S. typhimurium and 657 S. enteritidis from Africa, and 474 S. typhimurium and 676 S. enteritidis from America
