Phylogeny and network map of Eimeria zuernii haplotypes inferred on the basis of 54 cox1 data. a Topology tree of 24 haplotypes of E. zuernii. b Network map of E. zuernii haplotypes. Eimeria zuernii isolates from different geographic origins are shown in dark blue (Hongyuan), blue (Xinlong), light blue (Ya’an), gray (Guelph), pink (North America), dark red (Yangzhou), red (Ganzi), yellow (Daofu), purple (Luhuo), green (Ruoergai), and dark green (Litang). The small black dot represents the median vector, indicating unsampled or extinct haplotypes. The dotted cycle denotes the hypothetically ancestral haplotype. The proportion of haplotype frequencies is shown with sizable coils. The network branches linking the cycles show the relationships between the haplotypes
