Proventriculus: hemorrhages and edema.
Morphologic diagnosis:
Proventriculus: Mild acute multifocal hemorrhage and edema
Clinical description:
This image was taken 4 days post experimental inoculation with highly pathogenic avian influenza. After 4 days, there is still only mild inflammation and petechiation in this bird’s proventriculus. This illustrates that within a flock, the distribution and severity of lesions for HPAI, will vary from bird to bird.
Pathologic description:
The proventriculus has been opened to reveal the mucosal surface. There are rare small petechia over the mucosa and the wall of the organ is slightly thickened. Mural and serosal blood vessels are congested.
