Fig. 2.

Minimum spanning tree generated from MLST comparisons of Campylobacter jejuni strains isolated from animals, humans, meat, and water in Slovenia. Each circle represents one sequence type (ST), the clonal complexes (CC STs) are indicated by numbers. Node sizes represent higher strain numbers within one ST. Node colour indicates the origin of the strains: black (meat), dark grey (human), light grey (animal), white (water). The connecting lines between STs depict the number of allelic differences between them: one allele difference (black bold lines), two alleles difference (grey bold lines), three alleles difference (grey dashed lines), more than three alleles difference (grey dotted lines).
