Wallingford, UK: CAB International Technical Abstract: Bacterial kidney disease (BKD), caused by Renibacterium salmoninarum, is a prevalent disease that impacts the sustainable production of salmonid fish for consumption and species conservation efforts. The disease is chronic in nature and mortality most often occurs in 6–12 month old juvenile salmonids and prespawning adults (Evelyn, 1993). Renibacterium salmoninarum is a small (0.3–0.1 µm by 1.0–1.5 µm), nonmotile, nonspore-forming, nonacid-fast, Gram-positive diplobacillus (Fryer and Sanders, 1981). There is only one species described in the genus to date. Little is known about R. salmoninarum due, in part, to the technical difficulties of working with this slow growing and fastidious microorganism. R. salmoninarum was recently selected for complete genome sequencing, which will provide a first step toward a more comprehesive understanding of the biology of this microbe (http://micro.nwfsc.noaa.gov/rs-genome/).
