From: Analysis of a Clostridium difficile PCR ribotype 078 100 kilobase island reveals the presence of a novel transposon, Tn6164

Figure 2

Minimum spanning tree of all the PCR ribotype 078 isolates that contained an insert (50 or 100 kb), supplemented with strains not containing the element. Each circle represents either one unique isolate or more isolates that have identical MLVA types. Red circles indicate strains with full Tn6164 and blue circles indicate strains with half the element. The numbers between the circles represent the summed tandem-repeat differences (STRD) between MLVA types. Underlined numbers represent porcine strains and normal numbers represent human isolates. Thick red lines represent single-locus variants; thin green lines represent double-locus variants and dotted blue lines represent triple locus variants between MLVA types. Clonal clusters are defined by an STRD of <2 (pink area), and genetically related clusters are defined by an STRD of <10 (green area)
