The fish pathogen Renibacterium salmoninarum: growth in a microaerophilic atmosphere.
Renibacterium salmoninarum is the etiologic agent of bacterial kidney disease (BKD) occurring worldwide in salmonid fish. This bacterium has previously been regarded as a strict aerobic species. However, in this study it is shown that R. salmoninarum grows well in microaerophilic atmosphere, the colony size being larger and the colonies being more mucoid than in aerobic conditions. Microaerophilic cultivation might be one possibility to increase the sensitivity of the cultivation method for the detection of this slowly growing pathogen.
