| 摘 要： | 本文报道了淡水鱼类细菌性败血症的肝、脾、肾组织亚显微病理变化及防治方法，并比较了鲫、团头鲂、鲢、鳙患此病后的症状和病理变化都基本相同。呈败血症症状，只是垂死的鲫较团头鲂、鲢、鳙为严重而已，这与鲫的生命力较强有关。在光学显微镜还不能察觉细胞组织的病变时，在电镜下已呈现出细胞病理变化。肝、睥、肾等脏器最早出现的病变是细胞的膜性结构受损。在光学显微镜下看到肝细胞中有很多被苏木素深染的丝状物是高度密集成束的粗面内浆网。这是机体的一种补偿性反应。根据病原、病理变化及发病机理。研制出复合新药——鱼泰8号，并提出三步曲治疗方法及16条治疗注意事项，从而确保治愈率在95％以上．治愈了2000多公顷内的病鱼。从改善环境、加强饲养管理，提高鱼体抵抗力、及时杀灭病原出发，提出10条综合预防措施，在300公顷的鱼池中实施后均未发病。

| Abstract: | The bacterial septicemia is initially found in crucian carp at ChongmingCounty, Shanghai, October 1986. And it spread rapidly to 20 provinces. This disease makesvery high epidermic and mortality on cultured fish, Its glaring symptoms are the hemolysisand a great quantity of ascites in abdominal cavity. Many species of freshwater fishes such ascrucian carp, blunt snout bream, silver carp, big head carp, common carp and rice field eelwere murdered seriously and caused enormous losses to fishermen. At that time nobodymade a clear idea to the pathogeny and pathology of this disease, and now it has beenknown. Their important pathogens are bacteria of Aeromonas hydrophila. The researchcourse of this disease listed briefly in literature of the present paper. In this paper, thesuper-microhistopathology of the bacterial septicemia and that of crucian carp, etc, will bediscussed comparatively. Their general pathological characters of diseased fish are extensivehemolysis and hemorrhage in whole body, all organs were disintegrate, particularly thesubstantive organs. Initial diseased change is the membraneous stuctures to be damaged inliver, spleen and kidney. These symptom may be perceived under electromicroscope but cannot perceived under the lightmicroscope. Under lightmicroscope, much filiform matter dyedby hematoxylin are seen. Under electromicroscope, the filiform matter is rough endoplasmicreticulum and concentrated into sheaves. This is a compensated action. The pathologicalchange degree of crucian carp was slighter than other fishes at same time that owing to itsmore vitality. According to the pathogen and pathological changes, a new compoundmedicine "YUTAI 8" was developed for this disease, and 3 steps of therapeutic method and16 points for attention were raised. 2000 ha of cultured ponds were treated and the cure ratewas over 95%. And using "YUTAl 8" for prevention in 300 ha of cultured ponds, the effectwas good too. In meantime, 10 multiple preventive measures were raised for building upresistance to disease and restraining the pathogens on basis practices. |
