Dr. John Fryer and his first graduate student (ODFW) laid much of the groundwork for Bacterial Kidney Disease (BKD). Subsequently, ODFW, in collaboration with OSU, has developed, tested and implemented screening methods for detecting BKD Renibacterium in adult salmon. BKD is a serious infection of salmon caused by the bacterium Renibacterium salmoninarum. Disease signs include characteristic off-white lesions in the kidney, that usually progress to become a systemic infection that kills the host. The disease can be transmitted from the adult female via infected eggs to the progeny and has impacted many salmon and trout populations. Culling infected eggs during hatchery spawning has been one of the most effective tools in reducing levels of the disease in juvenile salmon.
