Pathology Studies On Aspergillosis In Poultry

In experimental aspergillosis in chicken, two routes of infection were used. 1. Intr~~roE Infection:Chickens were divided into 3 groups, each of 30 chicken. Chickens of the first group received 100.000 spore 3 succesive days. The second group received 300,000 spore in one dose while the third one roceived 100.000 spore in one dose.The pathological changhad no significant variation and no mortality was detected. In the intestines, the pathologicol findings were hyperp- lasia of the epithelial and lymphoid elements; ulcerative en-teritis and productive enteritis.In the livers, dystrophic chcnges of hepatic cells; prod-uctive cellular reaction mostly interlobular in distribution aswell as hyperplasia of the bile ducts were observed. In the lungs, hyperplasia of the bronchial lymph follicles as well as inter and intralobular productive cellular reaction of lymphoid type were also noticed. h In the kidneys, tubular neprosis, mesengiaration of the glomeruli and focal productive reaction were alsodetected.
