[Blood parasites of small wild mammals in Czechoslovakia]

The author investigated 4,853 specimens of wild living small mammals (43 species: Insectivora, Chiroptera, Lagomorpha, Rodentia, Carnivora) from Czechoslovakia for blood parasites. Trypanosomes were found in Talpa europaea, Sorex alpinus, Crocidura suaveolens, Myotis myotis, Apodemus sylvaticus, Apodemus flavicollis, Mus musculus, Rattus norvegicus, Clethrionomys glareolus and Microtus agrestis. Babesia was detected in Myotis emarginatus, Myotis myotis, Clethrionomys glareolus, Microtus arvalis and Microtus agrestis. Grahaemella was found in Talpa europaea, Sorex araneus, Neomys fodiens, Neomys anomalus, Myotis emarginatus, Myotis myotis, Apodemus sylvaticus, Apodemus flavicollis, Apodemus microps, Apodemus agrarius, Mus musculus, Clethrionomys glareolus, Arvicola terrestris, Pitymys subterraneus, Microtus arvalis, Microtus agrestis, and Microtus oeconomus. Spontaneous Bartonella-infection was ascertained in one Microtus arvalis and, in erythrocytes of one Sorex araneus, parasitic organisms very similar to Bartonella were found.
