FIG 1.

Results of Salmonella typing and virulence gene detection of 61 isolates. A phylogenetic tree was built to show the genetic relationship of 61 isolates and the visualization of core genome SNP typing. Different serovars were labeled with different colors, as shown in the right part near the heatmap. A parallel matching heatmap was aligned to the phylogenetic tree. The left side of the heatmap shows the CST, cgST, and ST results. Different colors are used to distinguish different types, as noted on the right side of the heatmap. The right part shows a detailed matrix of plasmids (IncQ1, IncX1, IncR), and VF genes. The presence of a plasmid or VF gene in an isolate is marked as pink, otherwise, it is marked as light blue.
