The autecology of small rodents and insectivores of the Tribec mountain range.

Small rodents and insectivores have become the main reservoirs of tick-borne encephalitis virus. In order, therefore, to demonstrate the dynamic and structural changes occurring in a natural focus of tick-borne encephalitis, information has been collected on the distribution, habitat, life-cycle, population density and extent of tick infestation of the rodents and insectivores that inhabit the Tribec region and adjacent parts of the Hronský Inovec Mountains. The following mammals are discussed: Sciurus vulgaris, Citellus citellus, Glis glis, Muscardinus avellanarius, Mus musculus, Micromys minutus, Apodemus flavicollis, A. sylvaticus, Microtus arvalis, Pitymys subterraneus, Clethrionomys glareolus, Arvicola terrestris, Sorex araneus, S. minutus, Neomys fodiens, N. anomalus, Crocidura suaveolens, C. leucodon, Erinaceus roumanicus and Talpa europaea. Many of these are important reservoirs of virus.

The relationship between the tick-borne encephalitis virus and the ticks and mammals of the Tribec mountain range.

The basic problem in the study of tick-borne virus diseases is to establish where the virus is maintained in nature. In general, this focus will be found where there are large and relatively stable populations of ticks, small rodents and insectivores. In the Tribec region the principal vector of tick-borne encephalitis (TBE) is Ixodes ricinus, although other species can circulate the virus under suitable conditions. The virus can persist during winter either in starving nymphs or adults or in non-starving larvae or nymphs. It can also persist in hibernating mammals, but this is a less important mechanism. Among the mammals, the insectivores (hedgehogs, shrews and moles) and certain rodents are hosts of ticks and reservoirs of TBE virus of great importance. During spring, game and farm animals play an important role and birds are important hosts when the number of small mammals is low. Thus the survival of TBE virus depends on a complex interaction of varying populations of tick vectors and vertebrate hosts that occur in different habitats influenced by different environmental conditions.
