Aspergillosis
Distribution
Aspergillosis has a worldwide distribution having been reported in almost all domestic mammals and birds and in numerous wild species. Aspergillus sp. organisms are capable of living both a saprophytic and parasitic way of life and susceptible hosts have numerous opportunities to contact this agent.
Aspergillosis is most often seen in wild and captive birds. Aquatic and scavenging wild species have the highest incidence rate while captive species are most susceptible when first subjected to captivity. This is especially true when an extended transporting is required in overcrowded and unhygienic conditions.
In Michigan, aspergillosis has been identified as a mortality factor in the mallard, canvasback, redhead, wood duck, common merganser, black duck, teal, Canada goose, mute swan, tundra swan, whistling swan, ring-billed gull, herring gull, Sichuan pheasant, ring-necked pheasant, ruffed grouse, wild turkey, raven, evening grosbeak, rose-breasted grosbeak, eastern bluebird, American robin, common grackle, peregrine falcon, red-tailed hawk, bald eagle, purple martin, snowy owl, great horned owl, black duck and common loon. It has also been found, but is a minor mortality factor in white-tailed deer.
Transmission and Development
Aspergillus fumigatus is widely present in nature and produces tremendous numbers of spores in a few days when placed in warm and moist conditions. Favored environments for the mold are damp litter in stubble fields, on moldy grass along riverbanks, on moldy grain or meal, and on rotting plant and animal material, especially damp hay and straw.
Birds usually become infected by inhaling dust-laden air containing spores or by ingesting spores while feeding on or near the contaminated sources. The inhaled or ingested spores lodge in the air sacs and begin to develop. If the large air sacs are involved, the walls...
