Abstract

Proliferative kidney disease is an acute inflammatory response to the replication of the myxozoan parasite Tetracapsuloides bryosalmonae within the kidney tissues of salmonid fish. Although research is ongoing the development of proliferative kidney disease is thought to be related to environmental conditions, specifically low flows and high water temperatures. Although the prevalence of fish kills related to PKD is currently, a large kill occurred in 2016 on the Yellowstone River, and changes in water temperature related to climate change may lead to more frequent fish kills. To understand this disease, is important to understand this mysterious organism that can lead to large scale mortality events.
