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.
Prevention:
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.
