Minimum spanning tree of the cgMLST allelic profiles of C. diphtheriae isolates detected among migrants, Germany, 2021–2022a (n = 45)
C. diphtheriae: Corynebacterium diphtheriae; cgMLST: core genome multi locus sequence typing; NA: not available (no information on country of origin); SL-AD: single-linkage allelic distance.
a An ad hoc C. diphtheriae cgMLST scheme of 1,553 target loci was used for the cgMLST analysis.
Samples are colour-coded according to the case’s country of origin and collection year if information was available. The blue font is used for SL-ADs. Clusters with a SL-AD of ≤ 5 are shaded in grey.
