在测试孵化场和野生鱼从安大略来源，我们分离出的细菌，有足够的共同特征与耶尔森氏菌鲁氏，这表明他们是这种生物体的菌株。三个分离自溪红点鲑（Salvelinus fontinalis）、虹鳟（萨尔莫gairdneri）和白鲑（Coregonus artedii）的分离株在生物化学上类似于Y. ruckeri，但与Hagerman株血清型I的抗血清有交叉反应。来自褐鳟鱼（萨尔莫trutta）的第四个分离株似乎与先前描述的三个血清型不同。先前从麝鼠（Ondatra zibethica）肠生化和血清学上获得的第五个分离株对应于Hagerman血清型。我们认为，Y. Ruckeri和其生化和血清学特性的变化比以前认为的要大。这些结果对鲑科动物肠道型红口病的诊断和防治具有重要意义。
During testing hatchery and wild fish from Ontario sources, we isolated bacteria that had sufficient characteristics in common with Yersinia ruckeri to suggest they were strains of this organism. Three isolates from brook trout (Salvelinus fontinalis), rainbow trout (Salmo gairdneri), and cisco (Coregonus artedii) biochemically resembled the sorbitol-fermenting Serovar II strain of Y. ruckeri, but gave cross reactions with antiserum to the Hagerman strain, Serovar I. A fourth isolate from brown trout (Salmo trutta) appeared to be different from the three previously described serovars. A fifth isolate previously obtained from muskrat (Ondatra zibethica) intestine biochemically and serologically corresponded to the Hagerman serovar. We suggest that the geographic range of Y. ruckeri and variations in its biochemical and serological properties are greater than previously believed. These findings are of significance in diagnosis and regulation of enteric redmouth disease of salmonids.Key words: Yersinia rucke...
