Figure 1. Minimum-spanning tree of core genome multilocus sequence typing with 1,553 targets of the nontoxigenic Corynebacterium diphtheriae sequence type 8 (ST8) isolate branch for isolates submitted from northern Germany, January 2015–June 2017. The branch of 41 ST8 typed isolates is shown, together with the 2 nearest isolates from other STs KL0875 (ST441) and KL0377 (ST123) and the reference genome used (GenBank accession no. BX248353). Allelic distances between isolates are indicated, clusters with allele difference <5 are shaded in gray, and the reference genome is shown in white.
