Great Lakes native salmonid species that have tested positive for Renibacterium salmoninarum include Atlantic salmon (Salmo salar), lake trout (Salvelinus namaycush), brook trout (S. fontinalis), and splake (S. fontinalis x S. namaycush).

Lake trout and brook trout are considered less susceptible to Renibacterium salmoninarum infection and may not experience mortality upon contracting Bacterial kidney disease (BKD); in contrast, Atlantic salmon are more susceptible and prone to mortality.

Other Great Lakes native species found harboring Renibacterium salmoninarum include lake whitefish (Coregonus clupeaformis), bloater (C. hoyi), lake herring (C. artedi), mottled sculpin (Cottus bairdi), white sucker (Catostomus commersonii), muskellunge (Esox masquinongy), channel catfish (Ictalurus punctatus), lake sturgeon (Acipenser fulvescens), and walleye (Sander vitreus).

Four of the Great Lakes' native species (splake, muskie, channel catfish, and lake sturgeon) represent new detections since 2005. Lake whitefish and bloater are believed to be less susceptible to Renibacterium salmoninarum infection and may not experience mortality upon contracting Bacterial kidney disease (BKD).

Strains of Renibacterium salmoninarum isolated from Lake Michigan have been found to be more virulent than those from the Pacific Northwest, and in some cases, have resulted in higher than anticipated levels of infection.

While Renibacterium salmoninarum affects multiple Great Lakes native species, as of 2006, prevalence and mortalities in infected fish had been relatively low.

More recent data from 2011 indicates that Renibacterium salmoninarum has become more widely distributed with varying prevalence throughout Michigan state hatcheries and wild populations. The bacterium was detected in brook trout at 1.7% to 54% prevalence; Atlantic salmon 1.7% to 50%; muskellunge, lake sturgeon, and channel catfish at 1.7% to 10%; and lake trout, splake, and lake herring at 1.7% to 5% prevalence.

Renibacterium salmoninarum was detected at low prevalence in Minnesota hatcheries and for the first time in lake trout from Mountain Lake, MN. The Minnesota Department of Natural Resources is considering whether or not to continue using that lake as a brood stock source.
