Aspergillus fumigatus Fresenius isolated from ornithogenic soil collected at Hallett Station, Antarctica

Aspergillus fumigatus was isolated with high frequency from samples of ornithogenic soil collected from an Adélie penguin rookery at Hallett Station, Antarctica. While A. fumigatus has been well documented as the principal incitant of aspergillosis among penguins in captivity, this represents the first report of its presence in antarctic materials. Aspergillus flavus and Aspergillus ustus were also found in the Hallett samples. In a comparable number of soil and guano samples from isolated Adélie rookeries on Foyn Island and Possession Island, these fungi were not encountered. It is suggested that their presence at Hallett Station may be the result of human contamination. A brief consideration of epidemiological implications is given.
