Figure 1

Source assignment by cut-off probability. The breakdown of the number of unique ST isolates assigned to each source (Figure 1A) and the numbers of cases assigned to each source (Figure 1B). Poultry sources are represented by blue bars, ruminant sources by red bars, wild bird sources by green bars) and unassigned by grey bars. As the cut-off source probability decreases, the number of unassigned STs and cases declines.
