Small rodents reservoires of leptospiroses in the forests of Posavina in Croatia

Small rodents from the subfamilies Murinae and Arvicolinae are a reservoires of infectious diseases affecting humans, domestic and wild animals. The paper presents the results of research on these mammals as the reservoirs of leptospiroses. The samples were collected from April to November 2000 in the forests of Posavina in Croatia. The forests are managed by 11 forest administrations of the public enterprise "Croatian Forests", Ltd. The following species of small rodents were detected: Apodemus agrarius, A. flavicollis, A. sylvaticus, Arvicolla terrestris, Clethrionomys glareolus, Microtus agrestis, M. arvalis and Mus musculus. The dominant species in the studied plots (44) were A. flavicollis and A. agrarius. Most individuals were captured in the forests managed by forest administrations Popovača (25.86 %) and Nova Kapela (17.94 %). 83.82 % of the animals were caught in the forest communities of Genisto elatae - Quercetum roboris caricetosum remotae, Genisto elatae - Quercetum roboris caricetosum brizoides and Carpino betuli - Quercetum roboris typicum. The majority of them were captured during autumn months. A total of 379 animals were analysed with the method of renoculture were down in Korthof's liquid medium and serological reaction to microscopic agglutination with 12 serological variants of the Leptospira. A total of 17 Leptospira strains were isolated with renoculture from the individuals of three rodent species (M. musculus, A. flavicollis and A. agrarius) caught in the localities in Kutina, Velika Gorica, Popovača and Nova Kapela. The antibody titre to Leptospira was identified in 48 animals of the following species: A. agrarius, A. flavicollis, M. musculus, C. glareoulus and A. sylvaticus.
