DNA/DNA hybridization and sequencing of rDNA (partial 18S rDNA and ITS1) were used to investigate phylogenetic relationships among seven host-specific Bothriocephalus parasites (Cestoda, Pseudophyllidae). The small nucleotide divergence between six of the seven bothriocephalids suggests that isolation and differentiation of Bothriocephalus lineages in the different host species probably occurred recently and over a short time span. Comparison of the molecular phylogeny of the parasite species to the phylogeny of their hosts (teleostean fishes) revealed little congruence between the branching patterns of hosts and parasites, suggesting that bothriocephalids have not cospeciated with their hosts.
采用DNA/DNA杂交和核糖体DNA测序（部分18S核糖体DNA和ITS1）来研究七种宿主特异性裂头绦虫寄生虫（绦虫纲，假叶目）之间的系统发育关系。七种裂头绦虫中的六种之间的小核苷酸差异表明，不同宿主物种中裂头绦虫谱系的隔离和分化可能是最近在短时间内发生的。将寄生虫物种的分子系统发育与其宿主（硬骨鱼类）的系统发育进行比较，发现宿主和寄生虫的分支模式之间几乎没有一致性，这表明裂头绦虫没有与其宿主共同物种形成。
