Bài viết nêu lên hội chứng chết sớm/hoại tử gan tụy cấp (EMS/AHPND) là bệnh trên tôm được phát hiện đầu tiên ở Trung Quốc năm 2009. Sau đó, bệnh lây lan nhanh chóng ra các nước lân cận và hiện đã có mặt tại hầu hết các vùng sản xuất tôm chính trên thế giới, trong đó có Việt Nam. Bệnh gây ra thiệt hại nghiêm trọng cho ngành tôm toàn cầu và cho đến nay vẫn chưa có phương pháp chữa bệnh hiệu quả. Mời các bạn cùng tham khảo! | 36 Trường Đại học Nông Lâm TP.

The disease Received March 26 2021 spread rapidly to neighboring countries and emerged in almost major Revised April 13 2021 shrimp-producing regions in the world including Vietnam. The disease Accepted April 22 2021 has caused serious damage to the global shrimp industry and so far there is no effective cure. In order to understand the current status of AHPND Keywords and then to introduce effective prevention and detection measures we collected data and shrimp samples in some provinces in the Mekong Delta to analyze and isolate the pathogenic strains. The results of our study AHPND conducted from 2014 - 2018 in four provinces Ben Tre Long An Bac ToxA Lieu Kien Giang showed that AHPND damaged from to of the ToxB total shrimp farming area. In addition we isolated 10 AHPND-positive V. parahaemolyticus strains via culturing and PCR. The results of representative sequencing of Whiteleg shrimp three strains LA1 LA5 and LA8 showed that they were 100 similarity with the previously published strain XN89. .
