A confirmed case of bacterial kidney disease in a sports-caught rainbow trout (Salmo gairdneri) from Loon Lake, British Columbia, is reported. The case represents the first record of this disease in an apparently wild fish in this province. Descriptions of the affected trout and of the causative bacterium are provided.

Bacterial Kidney Disease

Blood samples were taken from fingerling coho salmon (Oncorhynchus kisutch) that had been experimentally infected with either the bacterial pathogen causing vibriosis or that causing bacterial kidney disease. In the 2nd week after inoculation, smears from the Vibrio-infected fish contained enlarged thrombocytes, pinched erythrocytes, and neutrophils with vesicles. The total number of thrombocytes was reduced to 8000 per microlitre, though this returned to 20 000 per microlitre in the 3rd week in those fish that survived.Blood smears from fish given the kidney disease bacterium contained enlarged thrombocytes and what appeared to be collapsed reticulocytes, in the 2nd and 3rd weeks. The thrombocyte count averaged 6500 per microlitre, and there were reduced numbers of other cells. Bacteria were found in thrombocytes, neutrophils, and monocytes.Light micrographs of 26 normal or modified cells and electron micrographs of two granulocytes are included.

Disease Agent

Juvenile coho salmon (Oncorhynchus kisutch), sockeye salmon (O. nerka), and steelhead trout (Salmo gairdneri) were infected by intraperitoneal injection of a suspension of the causative organism of bacterial kidney disease at seven experimental temperatures from 3.9 to 20.5 °C. In coho salmon and steelhead trout percent mortality was maximal (78–100%) in the range of 6.7–12.2 °C. As the temperature increased above 12.2 °C mortality declined progressively; at 20.5 °C it was only 8–14%. The two highest temperatures had some suppressing effect on the disease, which was greatest at 20.5 °C. In sockeye salmon this was not apparent, as percent mortality was essentially 100% at all temperatures from 6.7 to 20.5 °C; this species appeared to be highly susceptible to the disease agent. Temperature also influenced the mean number of days between infection and death. This interval was shortest in all three species of salmonids at the higher temperatures, varying from 21 to 34 days at 15.0–20.5 °C. It increased progressively as temperature decreased below this range; at 6.7 °C it varied from 60 to 71 days among the three species.
