Clinical Signs:
Dehydration; Edema, hemorrhage, cyanosis (comb, wattles)
Morphologic diagnosis:
Comb and wattles: Mild edema, cyanosis and hemorrhage. Skin: Dehydration.
Clinical description:
This image was taken 2 days post experimental inoculation with highly pathogenic avian influenza. Birds infected with AI typically experience a significant drop in water and feed consumption. The subsequent dehydration, is often easiest to observe on the nonfeathered skin of the comb and wattles. The skin of the comb, as seen here, becomes dry and wrinkled.
Pathologic description:
The skin is dry slightly wrinkled. The subcutaneous tissues of the comb and wattles are slightly swollen. The comb and wattles are stippled by numerous, small, often coalescing faint red foci and the edges of the tissue are slightly purple.
