Clinical Signs: 
Soiled vent, diarrhea
Morphologic diagnosis: 
Vent: Diarrhea
Clinical description: 
This image was taken 2 days post experimental inoculation with highly pathogenic avian influenza. Pay attention to mild soiling of the feathers around the vent, as seen here, as this can provide a valuable clue, indicating the presence of mild early diarrhea. Chickens infected with AI often exhibit diarrhea. The diarrhea typically begins with bright green watery feces. As the disease progresses, feces may become totally white.
Pathologic description: 
There is a small amount of loose, watery feces around the vent
