Aspergillosis in livestock

摘要

The clinical signs such as dyspnea, gasping, cyanosis and hyperemia are usually associated with the disease. However, the affected birds normally don't produce respiratory noise associated with other respiratory problems. Moreover, Aspergillosis primarily causes high morbidity and mortality especially in young chicks. Aspergilli can be isolated from environmental samples and are worldwide in distribution due to the spores of these fungal pathogens are resistant in nature and the birds as well as people who work with them, coming in contact with spores through contaminated feed or litter and may get affected after inhaling the spores. Poultry farm workers are at high risk of developing respiratory problems as they are exposed to high levels of dust containing Aspergillus spores during handling and processing of contaminated material.
