本文报道在我国浙江省发现的鳗鲡爱德华氏病病原菌特征。从患病鳗鲡内脏分离到9株菌,用其中的E895205等4株菌进行人工感染,死亡率均为100％,与自然发病症状相似。这些菌株的特征一致。均为G~-短杆菌,单个,周鞭毛,兼性厌氧,发酵葡萄糖产酸产气。氧化酶阴性,接触酶阳性,产H_(?)S。不能利用柠檬酸盐和丙二酸盐作为唯一碳源,鸟氨酸和赖氨酶脱羧酶阳性。属爱德华氏菌属细菌。比较已报道的四个种,认为E895205等菌株为一新种,定名为浙江爱德华氏菌(Edwardsiella zhe jiangensis sp. nov.)。
This article reports on the characteristics of pathogenic bacteria of Edwards’ s disease found in Zhejiang Province in China. Nine strains of bacteria were isolated from diseased eel, and four strains of E895205 were used for artificial infection. The mortality rates were all 100%, which were similar to the natural ones. The characteristics of these strains are consistent. Are G ~ - Brevibacterium, single, weeks flagella, facultative anaerobic, fermentation of glucose acid production gas. Oxidase negative, positive contact enzymes, producing H_ (?) S. Can not use citrate and malonate as the sole carbon source, ornithine and lysine decarboxylase positive. Is Edward’s bacteria. Compared with the four reported species, the strain E895205 is considered to be a new species named Edwardsiella zhe jiangensis sp. Nov.
