1993~1994年我国沿海养殖对虾发生了特大的暴发性流行病,损失惨重。本文报道该病的特点、症状及危害,并在患病的中国对虾、日本对虾、长毛对虾的中肠、肝胰腺的上皮细胞核和细胞质及腹肌纤维间质中发现大量具有囊膜的杆状病毒。通过病毒引起宿主靶组织细胞的病理变化、无包涵体等特性分析,认为该病毒属于有囊膜杆状病毒科C亚群,不同于已知的对虾所有杆状病毒,为对虾的一类新致病病毒。文中还分析了主要致病原因,通过调查和试验提出8条有针对性的预防措施。
The 1993-1994 epidemic of prawn shrimp farming in coastal areas in our country was extremely serious and suffered heavy losses. This article reports the characteristics, symptoms and harms of this disease. In addition, a large number of capsule-shaped rods were found in diseased Chinese shrimp, Japanese shrimp, midgut of hepatopancreas, epithelial cell nucleus and cytoplasm of the hepatopancreas and abdominal muscle fibers virus. Pathogenic changes of the host target tissue cells caused by the virus and analysis of the characteristics of the inclusion bodies were considered as belonging to the C subgroup of the enveloped baculoviridae and different from all the known baculoviruses of shrimp and a new class of shrimp Pathogenic virus. The article also analyzed the main causes of disease, through the investigation and test proposed eight targeted preventive measures.
