Fig. 2From: Evaluation of a Stenotrophomonas maltophilia bacteremia cluster in hematopoietic stem cell transplantation recipients using whole genome sequencingMinimum spanning tree of S. maltophilia isolates. Minimum spanning tree of four blood culture isolates (P, yellow), one environmental isolate (E, green) from the HSCT unit and one outgroup isolate (Ref, non-HSCT unit, isolated in May 2016, grey) based on up to 1876 target genes, pairwise ignoring missing values. Genotypes are consecutively numbered, starting with P1 (isolated in February 2016). Each dot represents one genotype and is colored according to its origin. Different connecting lines and numbers on these lines show the number of alleles differing between two genotypesBack to article page
