The phylogenetic tree of 114 P. multocida based on the core genes. From the inside, the inner circle 1 marks the MLST CC (clonal complexes) corresponding to each strain, and the corresponding sequence type and colour are displayed on the right in the order in which they appear. Circle 2 shows the different geographical locations of the strain in the key colours on the right side, including North America (America and Canada), Asia (China, Thailand, India, Sri Lanka, Pakistan, Malaysia, and Iran), Europe (UK and France), South America (Peru) and unknown geographic sources (Table S1). Circle 3 shows the host source of the isolates
