A comparative study has been made of the haptoral morphology of four species of diplozoon (Monogenea: Diplozoidae) from the gills of fish exposed to different levels of water pollution in two river systems in eastern Europe. An examination of the haptors of Paradiplozoon homoion (Bychowsky & Nagibina 1959), Paradiplozoon ergensi (Pejcoch 1968) and Paradiplozoon megan (Bychowsky & Nagibina 1959) from chub caught in the River Morava, Czech Republic and of Diplozoon paradoxum (Nordmann 1832) from bream recovered from the River Volga, Russia has revealed abnormalities to the attachment clamps. Two abnormal conditions were found: structural alterations to the attachment clamps and changes in the number of attachment clamps; these occurred both singly and in combination. A higher frequency of abnormal attachment clamps was found in diplozoons from fish caught in the more polluted localities of both rivers. The abnormalities have been recorded and their morphology compared in the light of conditions of environmental stress.
对来自东欧两个河流系统中接触不同程度水污染的鱼类鳃部的四种双身虫（单殖吸虫纲：双身虫科）的交接器形态进行了比较研究。对从捷克共和国摩拉瓦河捕获的雅罗鱼身上采集的同形副双身虫（Bychowsky & Nagibina，1959年）、埃尔根斯副双身虫（Pejcoch，1968年）和梅根副双身虫（Bychowsky & Nagibina，1959年）的交接器，以及从俄罗斯伏尔加河捕获的鲷鱼身上采集的奇异双身虫（Nordmann，1832年）的交接器进行检查后发现，附着器存在异常。发现了两种异常情况：附着器的结构改变和附着器数量的变化；这些情况单独出现或同时出现。在两条河流污染更严重地区捕获的鱼类身上的双身虫中，发现异常附着器的频率更高。记录了这些异常情况，并根据环境压力条件对其形态进行了比较。
