Occurrence of Aspergillus fumigatus Fresen. in the Lung of an American Bison

Abstract

The incidence of respiratory mycosis, which has been a frequent cause of deaths among birds in the Zoological Society's Gardens in London for many years, appears to be low in mammals. Scott1, who studied the association of mycosis and tuberculosis in birds and mammals, recorded mycosis in monkeys and a wallaby; but in these cases, as in most others recorded during the past forty years in the reports of the pathologist to the Zoological Society of London published annually in the Proceedings of that Society, ihe identity of the fungi involved was not ascertained. Aspergillus fumigatus Fresen. is the usual cause of avian mycosis, and it has also been recorded as pathogenic to other animals and to man. The following case of a fatal and apparently uncomplicated mycosis in a bison due to the same fungus appears to be unique.
