Phylogenetic tree of the MCRPEC isolates from different origins. The MCRPEC isolates were collected from companion animals in this study (in red designations) and from humans, companion animals, farm animals and environment in China downloaded from the NCBI databases (in black designations). The hosts of isolates are indicated by different symbols at end of the branches. The lineages are indicated in the outside circle with different colors. Each isolate is labeled with its ST type in the outermost circle
