动物流行性溃疡综合症(EUS)的调查及启示

Investigation of the Epizootic Ulcerative Syndrome (EUS) and its Revelation

2009年,对动物流行性溃疡综合症在纳米比亚的流行情况进行了调查,比较并综合了2007年、2008年的数据。结果表明纳米比亚不是EUS的发源地;该病在纳米比亚的流行区域主要为赞比西河沿岸以及和安哥拉、赞比亚相邻的Kavango和Caprivi两个省;流行时间为6月～11月;幼鱼发病率高于成鱼。初步分析该病的发生与异地传播、高密度养殖、管理不善有关;提醒国内相关部门在进出口时高度重视;同时广大养殖工作者也要酌情采取预防措施。

In 2009, the prevalence of fish Epizootic Ulcerative Syndrome （EUS） in Namibia was surveyed and compared with that in 2007 and 2008. The results showed that Namibia was not the source of EUS; the endemic areas are mainly distributed along the Zambezi River, as well as in Kavango and Caprivi provinces next to Angola and Zambia; endemic time is from June to November, fish flies are easier to be infected than adult. According to the preliminary research, the occurrence and out-break of EUS are associated with long distance transmission, high-density cultivation and mismanagement. It warns that the domestic import and export departments should pay much more attentation to EUS and the aquaculturists should take appropriate preventive measures against EUS.
