异育银鲫溶血性腹水病的组织显微病理研究

本文报导了1986年以来，在上海郊县及江苏等省市引起异育银鲫大量死亡的疾病、目前在国内外尚未见有报导，是一种新的暴发性鱼病。为此我们进行了病鱼组织显微病理变化的观察。现将该病暂定名为异育银鲫溶血性腹水病。病鱼体表充血、出血，病情严重时肛门红肿，眼球突出，腹部膨大，腹腔内有淡黄色或红色腹水，肠壁充血发炎；有的病鱼骨骼肌也充血，鳞片竖起。各组织器官都发生病变，其中尤以肝、脾、肾为严重；肝脏肿大，质地极度柔软，呈弥漫性坏死，肝细胞的胞浆内有被苏木素深染的丝状物；脾脏大片坏死解体成淡红色一片；肾小体坏死，以至解体，肾小管及造血细胞也多数发生病变，并有细胞管型．

STUDIES ON THE MICROHISTOPATHOLOGY OF HEMOLYTIC ASCITESOSIS OF CRUCIAN CARP

Disease of crucian carp has universally occurred in fish-farms in Shanghai suburbs and Jiangsu province since 1986. The disease makes very high incidence and mortality on the cultured fish. The important symptoms is that the infected fish appears, body surface congested,bug-eyed, anus swollen and red with inflated abdomen,and a great quantity of ascites in abdominal cavity. The histopa-thological inspection revealed that all diseased fish suffered from hemolysis, and serious anemia followed. Erythrocytes swollen and many red granular matters after dyed with H. E. presented in the cytoplasm. Hemolysis ocuured in whole viscera of diseased fish,all organs and tissues degenerated and necrosis, especially the liver, spleen and kidney.Although some papers have reported the diseased case of common carp, eel, channel catfish and salmon with much ascites and a very bulgy abdomen, but they didn't notice and mention the hemolysis, therefore, this fish disease is denominated to be hemolytic ascitesosis of crucian carp. The pathogens are Aeromenas sobria and A. hydrophila.
