EMMONSIOSIS OF SMALL MAMMALS (RODENTIA, INSECTIVORA) IN SOUTHWEST MORAVIA, CZECH-REPUBLIC

Adiaspores of the fungus Emmonsia parva var. crescens were found in th e lungs of 13.4% of 746 small mammals (Soricidae, Arvicolidae, Muridae ) of 13 species caught from April to November 1994-1996 in six localit ies of southwest Moravia, an area not previously investigated for mamm alian emmonsiosis. The infected mammals were rodents of five species: 11.0% of the common vole (Microtus arvalis), 20.0% of the pine vole (M . subterraneus), 20.9% of the bank vole (Clethrionomys glareolus), 11. 3% of the yellow-necked field vole (Apodemus flavicollis), and 11.4% o f the wood mouse (A. sylvaticus) specimens. Emmonsia infection was sig nificantly more frequent in adult (20.3%) than in juvenile (8.7%) micr omammals and also varied according to site and habitat.
