Different methods of estimating the elimination potential of invertebrate hydrobionts, members of water biocenoses, in relation to freeliving instars such as egg (miracidium) and cercarium of O. felineus are considered. Calculatons and conclusions are based on field and laboratory investigation carried out in the period 1985-1992. The elimination process in biocenoses does not practically influence on the intensivity of infection, but influences significantly on the extensivity of the infection of the molluscs Codiella with O. felineus larvae. This process is also the cause of low extensivity of infection of Codiella in natural water reservoirs (usually less than 1-2.5%) in all infection centres of exUSSR area including Western Siberia. The eggs (miracidia) of O. felineus are eliminated with different effectivity by invertebrate of nectobentos (oligichaeta, molluscs, and with less rate by arthropods). Coracidia are eliminated generally by nectoplancton crustaceans and water insect larvae. Invertebrate hydrobionts eliminate about 70% cercaria of the number of cercaria of the number coming out the infected molluscs being intermedial hosts.
研究了估算无脊椎水生生物（水生物群落成员）对猫后睾吸虫自由生活幼虫（如虫卵（毛蚴）和尾蚴）清除潜力的不同方法。计算和结论基于1985 - 1992年期间进行的野外和实验室调查。生物群落中的清除过程实际上对感染强度没有影响，但对猫后睾吸虫幼虫感染软体动物Codiella的广度有显著影响。这个过程也是前苏联地区包括西西伯利亚所有感染中心天然水体中Codiella感染广度较低（通常低于1 - 2.5%）的原因。猫后睾吸虫的虫卵（毛蚴）被底栖无脊椎动物（寡毛纲、软体动物，节肢动物清除率较低）以不同效率清除。纤毛蚴一般被浮游甲壳动物和水生昆虫幼虫清除。无脊椎水生生物清除了约70%从作为中间宿主的受感染软体动物中逸出的尾蚴数量。
