Species: Wild Mammal, Caribou
Specimen:
Testicle
Shown:
Caseonecrotic orchitis caused by Brucella suis biovar 4
Plain-Language Description:
A swollen testicle sliced open shows crumbly, yellowish, dead tissue throughout caused by Brucella infection.
Pathology Description:
Cut section of enlarged testis with multifocal to coalescing tan, friable areas throughout the parenchyma and locally extensive hemorrhage within the capsule. Caseonecrotic orchitis caused by Brucella suis biovar 4
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.
