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。
This article reports that a large number of allogynogenetic crucian carp (Carassius auratus gibelio) deaths have been reported since 1986 in suburban Shanghai and Jiangsu provinces. At present, no reports have been reported at home and abroad, which is a new outbreak of fish disease. To this end, we observed the pathological changes of diseased fish tissues. The disease is tentatively known as heterotrophic crucian carp hemolytic ascites. Fish body surface congestion, bleeding, severe anorectal swelling, prominent eyes, abdominal enlargement, intra-abdominal pale yellow or red ascites, intestinal congestion hyperemia inflammation; some diseased fish also hyperemia skeletal muscle, scales erected. All tissues and organs lesions, especially in liver, spleen, kidney is serious; liver enlargement, the texture is extremely soft, was diffuse necrosis, hepatocytes cytoplasm hematoxylin deeply stained filaments; large splenic necrosis Disintegration into a light red; renal necrosis, and even disintegration, renal tubular and hematopoietic cells are also the majority of lesions, and cell tube.
