The first detection of BKD in Quebec was made in the spring of 1979 in a hatchery. A high mortality occurred in fish over a year old. The majority of the fish were positive by immunofluorescence and the bacteriun was isolated from some fish. Three weeks before the disease appeared, six ponds received fish from this hatchery. No mortality was observed in those ponds and in the middle of the summer the percentage of carrier fish by immunofluorescence was approximately 20%.
1979年春季,魁北克首次在一家孵化场检测到细菌性肾病(BKD)。一岁以上的鱼出现了高死亡率。大多数鱼通过免疫荧光检测呈阳性,并且从一些鱼中分离出了细菌。在疾病出现前三周,六个池塘接收了来自该孵化场的鱼。在那些池塘中未观察到死亡情况,并且在夏季中期,通过免疫荧光检测的携带细菌的鱼的比例约为20%。
