Analysis of the ITS1 loci of Spirocerca spp. a Templeton-Crandall-Sing (TCS) haplotype network of the ITS1 sequences of Spirocerca spp. Each colored circle represents a haplotype; circle size is proportional to the number of sequences sharing the same haplotype. The black circles denote hypothetical sequences connecting each haplotype. b Bayesian inference tree for the ITS1 haplotypes of Spirocerca spp. Bootstrap (BS) and posterior probability (PP) values, respectively, are shown above branches. Only BS and PP values above 50% or 0.5, respectively, are shown. Cylicospirura petrowi (KM434335.1) and Dirofilaria immitis (EU087700.1) sequences were used as the outgroups. The results of the Poisson tree processes (PTP) analysis are summarized to the right of the taxa names as grey scale bars with the support partition values found by the maximum likelihood and Bayesian solutions. The identity of each taxon in the tree and network is color-coded according to its geographical location
