MLST-based phylogenetic relationships. A Maximum-likelihood phylogenetic tree inferred from concatenated sequences of the MLST allelic loci of all clinical isolates of this study. The bootstrap values of the internal nodes and the genetic distance within and between eBGs (inset) are shown. B Maximum-likelihood phylogenetic tree based on the representative STs from Spain and the major prevalent STs reported globally. STs representing results from our study in Spain are colored in red. ⁑ST found in Spain and other European countries. * ST found in Spain and other European or Asian countries. ¤ ST found in Spain and other countries of Europe, Asia and North America. ˟ ST found in Spain and worldwide.
