Fig. 1From: Tolerance of clinical vancomycin-resistant Enterococcus faecium isolates against UV-C light from a mobile sourceMinimum spanning tree of the core genome sequences of the investigated isolates. Each circle (node) represents one isolate. The number between the nodes indicates the number of allele differences. The upper numbers in each circle indicate the Sequence type (ST). The lower numbers indicate the Cluster type (CT), if applicable. White or gray nodes represent isolates carrying VanA or VanB resistance determinants, respectivelyBack to article page
