Proventriculus: hemorrhages.
Morphologic diagnosis:
Proventriculus (serosa): Marked acute multifocal hemorrhage. Intercostal spaces: Mild acute multifocal hemorrhage.
Clinical description:
This image was taken 3 days post experimental inoculation with highly pathogenic avian influenza. These serosal hemorrhages on the surface of the proventriculus, are typical of HPAI. The virus causes extensive hemorrhagic lesions across many visceral organs as a result of widespread viral replication and necrosis of endothelial cells.
Pathologic description:
The serosal surface of the proventriculus is covered by numerous, variably-shaped, coalescing, bright red areas. Similar foci can be seen in the intercostal spaces, present at the bottom of the photograph.
