Fig. 1. Bloodstream isolates of Salmonella Typhimurium used in this study.
Isolates were collected from either the Unité des Bactéries Pathogènes Entériques of the Institut Pasteur Centres (n = 72, light blue) or the MLW Clinical Research Center (n = 608, dark blue). Bar graphs show the number of isolates of different sequence types collected by centre per year. Donut charts indicate the proportion of sequence types collected per country and show the total number of isolates from each location in the centre. Note that only isolates from African countries (M’gascar, Madagascar; Congo, Republic of the Congo) are shown in donut plots. Letters in superscript relate to the location on the map. The colour code is shown at the bottom of the figure.
