Aspergillosis In Birds
A fungal infectious disease caused by Aspergillusfumigatus in which the typical sign is gasping for breath especially in young chicks.
Transmission is by inhalation of fungus spores from contaminated litter (e.g wood shavings , straw) or contaminated feed. Hatcheries may also contribute to infection of chicks.
Signs and Symptoms:
Infected Chickens are depressed and thirsty.
Gasping and rapid breathing can be observed. Mortality is variable, from 5 to 50%. Gross lesions involve the lungs and air sacs primarily. Yellow white pinhead size lesions can be found.
There is no specific treatment for infected birds. The best is to remove and destroy affected birds. Strict hygiene in breeder (hatching eggs) and hatchery management is necessary. Amphotericin B and Nystatin Have been used in high value value-birds.
