FIG 2.

Minimum spanning tree of 32 A. baumannii isolates detected for cluster I (ICU-1) and cluster II (ICU-2) based on the allelic profiles of up to 3,319 target genes (see Tables S1 and S2 and the supplemental data set in the supplemental material) that were present in the isolates with the “pairwise ignoring missing values” option turned on in SeqSphere+ software during comparison. Each circle represents an allelic profile, i.e., the genotype, and is named by the isolate(s). The numbers on the connecting lines give the number of differing alleles. The size of the circle is proportional to the number of isolates with an identical genotype and the color of the circles represent the different wards.
