Abstract
The lung tissue of 1143 rodents of five species, caught at a number of sites and habitats in an agro-ecosystem (southern Moravia, Czech Republic) in 1988–1993, was examined for the presence of adiaspores of Emmonsia parva var. crescens (Emmons et Jellison) van Oorschot. The overall prevalence of adiasporomycosis was 16·6%, but its distribution varied significantly according to rodent species (Clethrionomys glareolus 37·6%, Apodemus flavicollis 33·3%, A. sylvaticus 21·1%, A microps 9·2%, Microtus arvalis 2·7%) and habitat (lucerne fields 2·8%, fields with other crops 10·6%, windbreaks 33·1%, woods 15·8%). Wooded areas have consistently higher prevalence rates of rodent adiasporomycosis than arable fields. Some windbreaks could form natural foci of adiasporomycosis in the agricultural, largely deforested landscape.
