Shrews and small rodents inhabit the drainage channel banks in reclai med areas and have their ownhelminth complex. The aim of the study is to conduct the 3rd research period during 2015–2019 the helminth fauna ofthese animals living on the drainage channel banks of model reclamation systems in Brest Polesie (south-western partof Belarus), to establish the species composition of helminths and the animal infection by these, and to compare the dataobtained with previous research periods. 4,000trap-days were worked out. 151 specimens of shrews of 4 species and510 small rodents of 8 species were caught. Animals were examined by the method of complete helminthologicaldissections. Their numbers were 3.78 and 12.75 individuals per 100 trap-days, and helminth infection was 94.7% and65.9%, respectively. 66helminth species were found in animals. The dominant helminth species in infection have beenidentified. The trematode Prosolecithus danubica Tkach et Bray, 1995 (definitive host: common shrew), theacanthocephalans Centhrorhynchus aluconis (Müller, 1780) (larval host: lesser shrew) and Moniliformis moniliformis(Bremser, 1811) (definitive host: striped field mouse) are new species of helminths for Belarus. New hosts in Belarushave been found for 6 helminth species. Shrews and small rodents are involved in the life cycles of bird, non-ruminantartiodactyl and carnivorous mammal helminths. Nine helminth species have significance for medicine and 7 species forveterinary science. The results are compared with data from the 1st (1996–1999) and 2nd (2005–2010) research periods.
