Phylogenetic relationship among Parascaris spp. based on the COI (a) and ITS (b) sequences using maximum likelihood (ML) and Bayesian inference (BI). Values higher than 50 are displayed on the trees. Bold indicates the sequence of this study. For COI, the sequences of P. univalens samples in horses and zebras were divided into three haplotypes (CHU1–CHU3); the Parascaris sp. in donkeys in Liaocheng were divided into five haplotypes (CHS1–CHS5); the sequences of samples in donkeys in Chifeng were divided into three haplotypes (CH1–CH3). For ITS, the sequences of P. univalens were divided into two haplotypes (IHU1 and IHU2); the Parascaris sp. were divided into one haplotype (IHS1); the sequences of samples in donkeys in Chifeng were divided into two haplotypes (IH1 and IH2)
