SUMMARY
Emmonsia crescens Emmons and Jellison, 1960, a pulmonary fungus of mammals, had been reported for England, Sweden, and Italy.
A survey of small mammals in Europe in 1959 established that this organism was also present in Norway, Finland, France, Germany, and Yugoslavia. Additional infected animals were found and numerous cultures were established in Sweden.
Some of the interesting records of this pathogen were as follows:
Arvicola t. terrestris, a vole from Hamar Norway. Very heavily infected.
Microtus sp., a vole near Moi Rana, in northern Norway, 27 kilometers south of the Arctic Circle.
Microtus agrestis, a vole from Sweden collected in 1845 and preserved in the Swedish National Museum.
Lutra lutra, an otter from Kopparberg County, Sweden, very heavily infected.
Ondatra zibethica, the American muskrat introduced into Europe, and Arvicola t. terrestris from near Helsinki, Finland. Numerous specimens of both infected, some heavily.
Lemmus sp., a lemming from Kilpisjärvi, north Finland, 69° N.
This survey demonstrates that E. crescens has a wide host and geographical distribution in Europe.
