Corynebacterial kidney disease of salmonids: Growth and serological studies on the causative bacterium

Comparative growth studies of 10 isolates of the Corynebacterium of salmonid kidney disease were quantified on four media. Greatest cell yield was obtained from Mueller-Hinton medium with 0.1% L-cysteine hydrochloride. Serological tests, in which rabbit antisera used against typical bacteria strains showed all to be antigenically homologous, provided a reliable method of identification.

Serological diagnosis of corynebacterial kidney disease of salmonids

An immunodiffusion test is described which provides a rapid, sensitive, and definitive diagnosis of corynebacterial kidney disease of salmonid fishes. Specific precipitin lines are formed within 24 h when rabbit antiserum is reacted with kidney disease cell suspensions or internal tissue homogenates containing the specific bacterium. No precipitin lines are formed with tissue homogenates from healthy fish or from those injected with other fish pathogenic bacteria.
