Clinical Signs:
Hemorrhage, edema (cloaca)
Morphologic diagnosis:
Cloaca: Severe acute diffuse mucosal hemorrhage and edema.
Clinical description:
This image was taken 2 days post experimental inoculation with highly pathogenic avian influenza. In highly pathogenic avian influenza, the virus has wide spread tissue tropism, resulting in the inflammation and necrosis of many different tissues and organs. In this chicken, there are severe hemorrhages and necrosis of the cloaca.
Pathologic description:
The vent is dilated, revealing the dark red, swollen cloacal mucosa. The lack of feathers around the vent is due to normal molting.
