The unrooted maximum likelihood phylogeny of the IncI1-I(Gamma) plasmid. Internal nodes with less than 75% bootstrap support—1,000 bootstraps—were collapsed. The phylogeny was built from the multiple sequence alignment of the concatenated core genes (33 genes and 24,173 bp). There were 23,180 invariant sites in the multiple sequence alignment. The bootstrap values are provided as internal node labels. Of the 27 clinical isolates and 16 farm isolates that had this plasmid, only ten clinical isolates (blue) and two farm isolates (orange) shared high similarity
