对虾传染性皮下及造血组织坏死病(IHHN)是国际兽疫局(OIE)划定的甲壳类其他重要疾病之一,它分布广泛,危害严重,对世界对虾养殖业的发展影响重大。随着国际贸易的不断发展,区域间个体的流动有可能造成该病病毒传播。有迹象表明,近几年来中国养殖对虾中已发现IHHNV,且呈流行趋势。目前,国际上已建立起多种标准检测方法以监控疾病的流行。本文就该病毒的病毒特性、感染宿主、传播途径、地理分布及诊断技术等方面的研究现状作一综述,旨为对虾病毒性流行病学调查及疾病监控提供参考。
Infectious hypodermal and hematopoietic necrosis (IHHN) of shrimp is one of the other important crustacean diseases delineated by the OIE, which is widely distributed and endangered. It has a significant impact on the development of shrimp aquaculture in the world. With the continuous development of international trade, the flow of individuals in different regions may cause the virus to spread. There are indications that IHHNV has been found in cultured shrimp in China in recent years and is in a trend. At present, a variety of standard testing methods have been established in the world to monitor the epidemic. This article reviews the research status of the virus, such as the virus characteristics, host infection, route of transmission, geographical distribution and diagnostic techniques. It aims to provide reference for the epidemiological investigation and disease surveillance of shrimp.
