The study deals with changes of the helminthofauna in shrews (Sorex araneus, Linnaeus, 1766 and Sorex minutus, Linnaeus, 1766) in ecosystems of Krusne hory Mts. (NW Bohemia) affected by industrial immissions compared with ecosystem of Kaplice (S Bohemia) non-affected by industrial immissions. The pollution degree of environment by industrial immissions was ascertained on the basis of examination of shrew digestive tract. Data on helminths found in the common shrew (Sorex araneus) and lesser shrew (Sorex minutus) trapped live in ecosystems of Krusne hory Mts. (36 shrews) and in control (non-affected) ecosystem (32 shrews) during autumn 2001 - 2002 are presented. 72 % (26/36) shrews were infested with helminths in affected area and 46.88 % (15/32) shrews were infested with helminths in non-affected area. Nine and seven helminth species were ascertained in affected and non-affected area, respectively. The analysis of the material revealed that, in ecosystems of Krusne hory Mts. (NW Bohemia) affected by industrial immissions are hosts more infected by helminths (P > 0.01).
