最近从法国患病的淡水鱼中分离出三株滑行细菌，类似于已知的鱼类病原体柱状柔杆菌。其形态、生理生化特征与国外已鉴定的6株柱状镰刀菌十分相似，可作为参考。这是法国首次明确鉴定出这种鱼的病原体。这种微生物区别于其他明显非致病的鱼源性滑行细菌的特征包括：它在固体介质上的强黏附和根状黄色平坦菌落；它对刚果红染料的吸收，以及它产生柔红素类型的色素。其他有用的区别特征是硫化氢的产生和硝酸盐的还原，对任何碳水化合物没有作用，卵磷脂快速而强烈的水解性，以及在含有超过0.5%的氯化钠的介质中没有生长。
Three strains of gliding bacteria resembling a known fish pathogen, Flexibacter columnaris, were recently isolated from diseased freshwater fishes in France. Morphological, physiological, and biochemical characteristics were very similar to those of 6 F. columnaris strains previously identified in other countries and used here for reference. This is the first unequivocal identification of this fish pathogen in France. Chracteristics of this organism that distinguish it form other, apparently non-pathogenic, gliding bacteria of fish origin include its strongly adherent and rhizoid, yellow, flat colonies on solid media; its absorption of Congo red dye, and its production of flexirubin-type pigments. Other useful distinguishing characteristics are the production of H2S and the reduction of nitrates, the absence of action on any carbohydrates, the rapid and intense hydrolysis of lecithin, and the absence of growth in media containing more than 0.5% NaCl.
