STRUCTURE analysis of B. dermatitidis haplotypes. Mean q-values from STRUCTURE for all 196 unique haplotypes (representing 301 isolates) with K = 2. Group 1 haplotypes are shown in black and Group 2 haplotypes in gray. Haplotypes 1–54 represent exclusively canine isolates. Haplotype 55 represents the single equine isolate. Haplotypes 56–59 represent feline isolates. Haplotypes 61–87, 89–91, 93–194, and 196 represent exclusively human isolates. Haplotypes 88, 92, and 195 contained both human and canine isolates. Five haplotypes (1, 61, 111, 134, and 190, representing only one isolate each) had a majority q-value <80% and could not be assigned to either genetic group.
