CN: 23-1385
Species: Wild Mammal, Caribou
Specimen:
Kidney
Shown:
Focal chronic cortical granuloma with dystrophic mineralization caused by Brucella suis biovar 4
Plain-Language Description:
Caribou kidney with one white-ish 1-cm nodule. On slicing into this, the pathologist found yellow-tan cheese-like dead tissue, which is typical of Brucella infection.
Pathology Description:
A single 1.0cm diameter nodule that contains caseous, tan-yellow material
Pathology:
Brucellosis
General Information:
In the Arctic, brucellosis is a highly contagious disease that occurs in caribou and muskoxen, and rarely in other species (e.g., moose). It is caused by the bacterium Brucella suis biovar 4 and most often affects the reproductive organs and leg joints. Infected animals may appear healthy, but often they will have swollen joints and may limp. Other signs of brucellosis are swollen, bigger-than-usual testicles, udder, or uterus. Affected animals may also have yellow-white spots or lumps (small abscesses) in their muscle tissue, kidneys, or other organs. Brucella is a zoonotic bacterium, meaning it can be transmitted between animals and people.
