Phylogenetic tree comparing the geographical distribution between mtDNA cox1 gene haplotypes of Echinococcus multilocularis. The Bayesian phylogenetic analysis was used by setting the “TIM3+I” substitution model, 2,000,000-generation MCMC posterior probability estimation with a 1000-generation sampling interval, and discarding the first 25% samples when summing up trees
