Abstract

The distribution of F-actin in the monogenean Entobdella soleae (van Beneden et Hesse, 1864) Johnston, 1929 (Platyhelminthes: Capsalidae) was revealed by staining paraformaldehyde-fixed specimens with FITC-labelled phalloidin. On the ventral surface on the left side of the body, just posterior to the pharynx, a concentrically arranged array of fluorescent fibres was observed, following a circular path around the tiny ventral opening of the vagina. It is assumed that this asymmetrically placed array of actin fibres is contractile and the possible role of these fibres in the assimilation of sperm from an attached spermatophore into the vagina is discussed.

摘要

通过用异硫氰酸荧光素（FITC）标记的鬼笔环肽对经多聚甲醛固定的标本进行染色，揭示了单殖吸虫——鳎艾氏吸虫（Entobdella soleae）（范·贝内登和黑塞，1864年）约翰斯顿，1929年（扁形动物门：锚首科）中F - 肌动蛋白的分布情况。在虫体左侧腹面，紧挨着咽的后方，观察到一组呈同心排列的荧光纤维，围绕着微小的阴道腹侧开口呈圆形路径分布。据推测，这种不对称排列的肌动蛋白纤维具有收缩性，并讨论了这些纤维在将附着的精荚中的精子吸收到阴道中的可能作用。
