Reciprocal subtractive libraries were prepared for two strains of Flavobacterium psychrophilum, one virulent and the other avirulent in a trout challenge model. Unique clones were sequenced and their distribution assessed among 34 strains. The analysis showed that F. psychrophilum is composed of two genetic lineages, possibly reflecting host specificity.
针对嗜冷黄杆菌的两个菌株构建了消减文库,其中一个菌株在鳟鱼攻毒模型中具有致病性,另一个则无致病性。对独特的克隆进行测序,并评估它们在34个菌株中的分布情况。分析表明,嗜冷黄杆菌由两个遗传谱系组成,这可能反映了宿主特异性。
