Maximum-likelihood phylogenetic tree of Bordetella pertussis isolates on the basis of genome-wide single-nucleotide polymorphism analysis, showing macrolide-resistant isolates from Peru within the emerging MR-MT28 lineage (red text) among globally distributed strains. Tohama I (NC_002929) was used as the reference genome. PRN, pertactin.
