Nontoxigenic Corynebacterium diphtheriae Infections, Europe
To the Editor: We read with interest the article by Dangel et al. analyzing nontoxigenic Corynebacterium diphtheriae infections in northern Germany during 2016–2017 (1). Among the cases, 2 patients originated from Poland; each experienced an invasive disease, 1 endocarditis and 1 sepsis. Poland and Germany are neighboring countries. In Poland, we also observed an accumulation of nontoxigenic C. diphtheriaeinfections during 2016–2017. In both countries, most infections were caused by isolates belonging to sequence type (ST) 8 biotype gravis, which we previously suspected of having increased pathogenic properties (2).
