The mass infection of larvae and youngsters of carp fishes with the peritrichoid Ambiphrya ameiuri has been recorded in natural condition in the Rybinsk water reservoir. The uneven localisation of ambiphyrans on the body surface has been observed on the hosts Blicca bjorkna and Abramis brama. Most high density of parasites was on the breast, back and tail fins. The morphological variability of ambiphyrans in dependence upon their localisation on the fish body has been observed. Details being significant for the taxonomy have been studied by means of the scan electron microscope. It has been found that the scopulae (greatly developed attaching organ of A. ameiuri) in cases of heavy infection cover about 50-60% of the skin epithelium of fish larvae. In these cases the significant part of skin epithelium, which performs the respiratory function is excludes of the active oxygen supply that cause the illness and death of young fishes.
在雷宾斯克水库的自然条件下，已记录到鲤鱼幼鱼和稚鱼被周丛类的美洲双眉虫大量感染。在宿主银鲫和欧鳊身上观察到双眉虫在鱼体表的分布不均匀。寄生虫密度最高的部位是胸鳍、背鳍和尾鳍。观察到双眉虫的形态变异取决于它们在鱼体上的位置。通过扫描电子显微镜研究了对分类学有重要意义的细节。结果发现，在感染严重的情况下，美洲双眉虫的帚状板（其高度发达的附着器官）覆盖了约50%-60%的鱼幼体皮肤上皮。在这些情况下，执行呼吸功能的皮肤上皮的重要部分被排除在活跃的氧气供应之外，这导致幼鱼患病和死亡。
