Prophages have broad geographical distributions. World map overlaid with pie charts of prophage relative abundances in six continents (from left to right: North America, South America, Europe, Africa, Oceania, and Asia). To aid visualisation only prophages found in more than two isolates are shown (see Fig. S6 for all). Black lines link pie charts to continents. Numbers in brackets refer to the number of prophages represented by each pie chart for each continent. Map is available at https://www.naturalearthdata.com/
