Two Proteocephalus species, P. neglectus La Rue, 1911 and P. exiguus La Rue, 1911, parasites of salmonid and coregonid fishes, were compared morphologically, biometrically, and electrophoretically. The study revealed that the two taxa cannot be differentiated by the morphological criteria used. No fixed allelic difference was found. In all, 12 of 13 enzymes detected by isoelectric focusing exhibited virtually identical isoenzyme profiles in both species. Only in the glutamate oxaloacatate transaminase enzyme locus was a difference observed. The negligible differences in zymograms and morphology, including similar biometric variability of the taxa studied, suggest that the species could be conspecific.
对两种寄生于鲑科和白鲑科鱼类的头槽绦虫属物种,即1911年拉鲁命名的忽视头槽绦虫(Proteocephalus neglectus)和1911年拉鲁命名的微小头槽绦虫(Proteocephalus exiguus)进行了形态学、生物统计学和电泳分析比较。研究表明,无法通过所采用的形态学标准区分这两个分类单元。未发现固定的等位基因差异。通过等电聚焦检测的13种酶中,有12种在两个物种中呈现出几乎相同的同工酶谱。仅在谷氨酸草酰乙酸转氨酶酶位点观察到差异。酶谱和形态的差异可忽略不计,包括所研究分类单元相似的生物统计学变异性,这表明这两个物种可能为同种。
