The purpose of this study was to compare the occurrence of Emmonsia parva var. crescens in populated and unpopulated habitats of a rural area (in a village with 615 inhabitants and in surrounding forests without human population) as indicated by findings of adiaspores in lungs of small rodents captured in these habitats. Adiaspores of E. parva var. crescens were found in lungs of 13 out of 135 examined rodents. Four rodent species out of 7 were infected: Clethrionomys glareolus - 15.6 %, Mus musculus - 5.6 %, Apodemus sylvaticus - 3.2 % and Apodemus flavicollis - 16.7 %. The highest prevalence was found in A. flavicollis and C. glareolus in the village and in the forests, respectively. The infection intensity was low or moderate (below 100 adiaspores per animal). The highest prevalence of the infection was found in spring. The prevalence was not influenced by the sex of the animals. The occurrence of both saprophytic stage of E. parva var. crescens and rodents can be enabled by the plant cover of uncultivated soil in the village where the same plant species as in the surrounding forests occur. Therefore the risk of infection for humans and animals is not limited only to forest (unpopulated) habitats.
