Transmission of clade IC1 within Iceland. (A) A phylodynamic analysis was conducted to reconstruct the transmission of the IC1 clade across Iceland. The tree is coloured according to the most likely location of each branch, as determined through the discrete states phylogeographic model described by . The locations are clustered by region in the key. (B) Each isolate’s resistance profile is represented by red bars indicating full resistance, purple bars indicating intermediate levels of resistance and blue bars indicating sensitivity to the antibiotics annotated at the top of the column; white bars indicate missing data. (C) The isolates are classified according to the phenotypic groups one to six defined in  based on resistance phenotype and genotype, which are described in the main text.
