日本國際協力機構(JICA)和日本科學技術振興機構(JST)日前宣布，在早期死亡綜合癥(EMS，困擾泰國和東南亞地區并引起對蝦大量死亡的病害)研究中取得了突破性進展。
6月25日，這兩個機構宣布：他們已經確定EMS是對蝦被一種副溶血弧菌感染、引起消化器官功能紊亂所致，而且他們想出一個能100%精準度檢測出致病菌存在與否的診斷方法。
EMS的致死率可達100%，對抗EMS很有必要及早檢測并封閉或消毒池塘。然而，過去的診斷方法在樂觀情況下或無毒副溶血弧菌檢出情況下、病害沒有發生時就封閉池塘。而新的檢測方法，可以100%區分無毒菌株和致病毒株，所以這對有效隔離EMS和提高生產有著很大的貢獻。
這個突破性進展是JST/JICA“為食品安全和下一代食品安全開發水產養殖技術”項目的一部分，該項目由東京海洋大學、日本國際研究中心農業學科和國家水產養殖研究所和泰國漁業部門、泰國農業大學、泰國公立大學之朱拉隆功大學、泰國瓦萊嵐大學承擔。

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.
