鲍氏不动杆菌——鳜鱼暴发性死亡的新病原

１９９５年广东某地人工养殖的鳜鱼暴发传染病，大量病鱼急性死亡，引致严重经济损失，本试验从已接种嗜水气单胞菌和柱状噬纤维菌疫苗的病于脏器中分离到一种细菌，经腹腔注射和腮部接种人工感染健康鳜鱼及罗非鱼，均复制出与自然发病相似的病例，主要特点为肝脏严重变性，从上述人工感染的病鱼体内再次分离与自然发病相似的病例，主要特点为肝脏严重变性，从上述人工感染的病鱼体内再次分离到与自然发病相同的细菌。该菌为革兰氏阴

ACINE TO BACTER BAUMANNH A NOVEL PATHOGEN OF ACUTE EPIDEMIC IN MANDARIN FISH (SINIPERCA CHUATSI)

In last few years, a new acute epidemic disease with high mortality occured among oultured mandarin fish (ffeoperco chuatsi) which had been inunuinzated with vaccines of Aermas hydroPhila and Cytophaga columnaris in Guangdong Provinee, China. Bacteriological exndnation revealed that all isolates from moribund fish liver had the same characteristics,eg. Gram-negative, coccirod, no motile, oxidase negative and catalase positive.In addtion,the isolated colony Anght produce fluorescenee. Inoculating the strains to mandarin fish, tilapia and mouse for lethality indicated the germ had pathogenicity, and the same bacteritun could be recovered from these experimelltal animals, The results suggsted the bacterium was the cavstive apellt of this disease. Conclusively, morphological, cultural and biochendcal tests demonstrated that the ndcroorganism isolated from mandarin fish was Acinehoacter baumannii.
