Haplomycosis in Montana Rabbits, Rodents, and Carnivores

Abstract
Haplomycosis, a pulmonary disease of mammals caused by infection with Haplosporangium sp., was first found in ground squirrels, mice, and kangaroo rats in a semidesert area in Arizona. Mice and a tree squirrel in Alberta, Canada, and a beaver in Minnesota, have been reported infected. This fungus is here recorded for the following hosts from w. Montana: beaver, muskrat, pine squirrel, and white-footed mouse of the order Rodentia; rock rabbits and cottontails of the order Lagomorpha; mink, pine marten, skunk, and weasel of the order Carnivora. The known mammalian hosts of Haplosporangium sp. have a wide geographical, ecological, and zoological distribution.
