日本国际协力机构(JICA)和日本科学技术振兴机构(JST)日前宣布，在早期死亡综合症(EMS，困扰泰国和东南亚地区并引起对虾大量死亡的病害)研究中取得了突破性进展。
6月25日，这两个机构宣布：他们已经确定EMS是对虾被一种副溶血弧菌感染、引起消化器官功能紊乱所致，而且他们想出一个能100%精准度检测出致病菌存在与否的诊断方法。
EMS的致死率可达100%，对抗EMS很有必要及早检测并封闭或消毒池塘。然而，过去的诊断方法在乐观情况下或无毒副溶血弧菌检出情况下、病害没有发生时就封闭池塘。而新的检测方法，可以100%区分无毒菌株和致病毒株，所以这对有效隔离EMS和提高生产有着很大的贡献。
这个突破性进展是JST/JICA“为食品安全和下一代食品安全开发水产养殖技术”项目的一部分，该项目由东京海洋大学、日本国际研究中心农业学科和国家水产养殖研究所和泰国渔业部门、泰国农业大学、泰国公立大学之朱拉隆功大学、泰国瓦莱岚大学承担。

TheJapan International Cooperation Agency and the Japan Science and
Technology Agency have announced a breakthrough in the fight against Early
Mortality Syndrome (EMS), a cause of mass deaths of shrimp afflicting Thailand
and the ASEAN region.
On 25 June, the two agencies announced they have determined EMS is due to
shrimp being infected with a type of Vibrio parahaemolyticus that causes
digestive organ disfunction, and they have come up with a diagnostic method that
can detect the presence or absence of the bacterium with 100 per cent
accuracy.
To fight EMS, which is said to have a mortality rate of 100 per cent, it is
necessary to diagnose it early and shut down or disinfect fish ponds. However,
because past diagnostic methods yielded positives even in the case of avirulent
Vibrio parahaemolyticus, fish ponds were shut down even when the disease had not
actually broken out.
The new diagnostic method, however, can distinguish the virulent strain
from the avirulent one with 100 per cent accuracy, so it is expected to greatly
contribute to efficient quarantining of EMS and improve production.
The breakthrough was part of the project JST/JICA Project: Development of
Aquaculture Technology for Food Security and Food Safety in the Next Generation,
which is being carried out by Tokyo University of Marine Science and Technology,
Japan International Research Center for Agricultural Sciences and National
Research Institute of Aquaculture in Japan, and in Thailand, the Department of
Fisheries, Kasetsart University, Chulalongkorn University and Walailak
University.
