A variety of domestic and wild animals are considered to be potential sources of cryptosporidiosis in humans. However, despite considerable information available on Cryptosporidium spp. in humans and ruminants, a paucity of information exists for many species of wildlife rodents. The current study reports the prevalence of Cryptosporidium infection among rodent populations from different habitats in northern Poland. In autumn 1996, spring and summer 1997, a total of 287 animals (8 species of rodents from three different habitats: Clethrionomys glareolus and Apodemus flavicollis and A. sylvaticus from forest; A. agrarius, Microtus arvalis and M. oeconomus from field/meadow; Castor fiber and Ondatra zibethicus from semi-aquatic habitat) were examined for Cryptosporidium oocysts. Direct wet smears from unconcentrated faecal specimens were stained using a modified Ziehl-Neelsen method and/or direct immunofluorescent (MerIFluor Cryptosporidium/Giardia) assay. Faecal examination revealed that 41 of 132 (31%) C. glareolus, 26 of 96 (27%) Apodemus sp., 19 of 28 (68%) Microtus sp., 1 A. agrarius, 2 of 19 (10.5% colonies*) of C. fiber and 5 of 12 (42%) O. zibethicus were infected with Cryptosporidium oocysts. The intensity of infection was generally low, with <5 oocysts/slide film in most of the samples studied. The morphological characteristics and measurements of the oocysts (mean size 4.8 x 4.5 µm) conformed with those of C. parvum. This study indicates, for the first time in Poland, that semi-aquatic rodents, mostly O. zibethicus, and possibly rodents from other habitats may be involved as reservoirs of infection for C. parvum.
