新疆红雁池鱼场非洲鲫鱼传染病病原学研究初报

红雁池鱼场利用电场冷却电机回流水饲养非洲鲫鱼。１９８２～１９８３年分３批从北京小唐山温泉鱼场引进非洲鲫鱼，进场不久即大批死亡，死亡率由１８．３７％到几乎全群覆灭，造成很大的经济损失．经采样进行细菌分离与鉴定并对菌株作药敏试验，同时将病鱼组织磨碎，匀浆后进行差速离心和梯度离心沉淀，点样用磷钨酸和醋酸氧铀分别染色作电镜观察。其结果为；电镜检查未发现病毒，细菌学检查分离出８株细菌。分离出的细菌以气单胞菌属菌为主（８株菌中、气单胞属菌占６株），因此定名为气单胞菌感染复合症（ＡｅｒｏｍｏｎａｄＭｉｘｅｄＩｎｆｅｃｔｉｖｅ　Ｃｏｍｐｌｅｘ）。分离上述菌株对小白鼠有较强致病力，鉴于国外文献报道气单胞菌属偶能引起人传染性胃肠炎，故本病可能为人鱼共患病，特此报道．警惕注意。

Preliminary Report on Etiologic Agents of Infectious Disease of African Crucial Carp in Hong Yianchi Fishing Ground Xinjiang

Aftican crucial carp are raised in a back-running water from a cooling-machine of power station at Hong Yianchi. During 1982-1983 three batches of african crucial carp from Beijing Xiaotiangshan hot fountain fishing ground were introduced to the fishing ground. Arter a while,the fishes began to die and caused great economic loss,the mortality rate is from 18.37% to 100%.Isolation and identification of bacteria and drug sensitivity tests were made by the authors.Meamwhile the diseased fish tissues were treated and detected under electron microscope.The result showed that no virus was fornd,but 8 strains of bacteria were isolated and identified,6 out of them were aeromonas and so the infectious disease was named aeromonnd mixed infective complex.The isolated strains had hish pathogenicity to mice.since it is reported abroad that aeromonas occasionally cause transmissible gastroenteritis in humans;It may be Zoonosis,The authors reported the infectious disease in order to remind people to pad attention to it.
