Flamingo: Kidney: Amyloidosis, diffuse, severe, chronic

04_2013_big

Animal:

Flamingo, adult, female

Diagnosis:

Kidney: Amyloidosis, diffuse, severe, chronic

Description:

Both kidneys were diffusely swollen, pale and yellowish.

Comments:

Clinically, the flamingo presented with diarrhoea and a poor general condition. At necropsy the flamingo was emaciated and the carpal joint of the right wing had a chronic suppurative to proliferative arthritis. In addition to the kidneys, extensive amyloid depositions were histologically present in the spleen, liver and intestine. Diarrhoea was attributed to intestinal amyloidosis with consecutive reduced nutrient absorption and emaciation. Possible causes of generalized secondary amyloidosis especially in avian species are, amongst others, aspergillosis, mycobacteriosis and various parasitic infections / infestations.
