8560 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field Lake whitefish (Coregonus clupeaformis) collected from Lake Michigan and Lake Huron between 2003 and 2006 tested positive for Renibacterium salmoninarum at a prevalence of 62.31%. Lake whitefish have a high commercial value in the Great Lakes, and if populations were to fluctuate significantly as a result of Bacterial Kidney Disease (BKD) infection, there could be serious economic effects. Great Lakes, USA 24328
8561 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field Great Lakes non-native species that have tested positive for Renibacterium salmoninarum include Chinook salmon (Oncorhynchus tshawytscha). Lake Michigan, USA 16560
8562 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field Great Lakes non-native species that have tested positive for Renibacterium salmoninarum include Chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), rainbow trout (O. mykiss), and sea lamprey (Petromyzon marinus). Humber River and Duffins Creek, Lake Ontario 16555
8563 Renibacterium (Corynebacterium) salmoninarum Commerce Anecdotal N/A Rainbow trout (Oncorhynchus mykiss) are less susceptible to Bacterial kidney disease (BKD) infection and may not experience mortality upon contracting the disease, whereas coho salmon (O. kisutch) and Chinook salmon (O. tshawytscha) are more susceptible to infection and more prone to mortality. Little Manistee River, Michigan, USA 16558
8564 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field Prevalence rates of Renibacterium salmoninarum were up to 100% in some parts of the Lake Michigan drainage around 1986. This outbreak of Bacterial kidney disease (BKD) caused heavy mortality in Chinook salmon in 1988 and persisted in the population until 1992. That year, boat fisheries observed at least a 40% decline in Chinook salmon catch per unit effort levels. By 1993, catch per unit effort was 15% of the peak observed in 1986. Lake Michigan, USA 16560
8565 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field In 1986, the Strawberry Creek spawning weirs in Wisconsin documented no presence of Renibacterium salmoninarum. In 1988, the bacterium was isolated in 67% of the returning Chinook salmon and then persisted at moderate levels through 1992. Lake Michigan, USA 16560
8566 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field The mortality events of the 1980s are believed to have also been influenced by increased vulnerability due to food shortages, particularly alewives (Alosa pseudoharengus), high Chinook salmon density, and high parasite loads of Renibacterium salmoninarum. Lake Michigan, USA 16560
8567 Renibacterium (Corynebacterium) salmoninarum Commerce Observational Field While significant for the fisheries at that time, given the magnitude of the stocks present in Lake Michigan, it is improbable that the Chinook salmon die-offs from Renibacterium salmoninarum observed in the late 1980s and early 1990s caused a residual demographic bottleneck in those populations. Lake Michigan, USA 16570
8568 Renibacterium (Corynebacterium) salmoninarum Commerce Anecdotal N/A As of 2006, the overall prevalence of Renibacterium salmoninarum in non-native Great Lakes species was thought to be low and declining over time. Great Lakes, USA 16496
8569 Renibacterium (Corynebacterium) salmoninarum Commerce Anecdotal N/A However, in 2011, Renibacterium salmoninarum was widely distributed with varying prevalence throughout Michigan state hatcheries and wild populations. The bacterium was detected in brown trout (Salmo trutta) at 1.7% to 54% prevalence, rainbow trout at 1.7% to 40%, coho salmon at 1.7% to 10%, and Chinook salmon at 1.7% to 5% prevalence. Michigan, USA 31846
8570 Renibacterium (Corynebacterium) salmoninarum Commerce Anecdotal N/A Renibacterium salmoninarum was detected in 11 out of 12 production lots of rainbow trout and coho salmon from 4 out of 5 Indiana state hatcheries, with prevalence ranging from 1.67% to 26.67%. Six cases exceeded 10%. Indiana, USA 31846
9660 Renibacterium (Corynebacterium) salmoninarum Commerce Anecdotal N/A Bloater is a staple of Great Lakes native and non-native salmonid diets. Therefore, reductions in salmonid populations from Renibacterium salmoninarum economic effects to the Great Lakes fishing industry could be realized if bloater populations decline.
