    Abstract


    Bệnh hoại tử gan tuỵ cấp (AHPND) đã và đang được xem là một bệnh tôm nguy hiểm mới xuất hiện gần đây ảnh hưởng đến nghề nuôi tôm nước lợ ở khu vực Đông Nam Á trong đó có Việt Nam. Bệnh được ghi nhận đầu tiên tại các trang trại nuôi tôm ở Trung Quốc vào năm 2009, sau đó lần lượt được phát hiện thấy ở Việt Nam và Malaysia năm 2011, Thái Lan năm 2012 và Mexico năm 2013. Các nhà khoa học đã phát hiện ra rằng AHPND bị gây ra bởi các chủng vi khuẩn thuộc nhóm Vibrio. Các chủng vi khuẩn gây bệnh AHPND có chứa Plasmid mang các gen độc lực Pir A/B mã hoá cho các protein gây ra hiện tượng hoại tử cấp ở gan tuỵ tôm. Bài viết này sẽ cập nhật tất cả các thông tin về AHPND, bao gồm các thông tin về dịch tễ học và các yếu tố nguy cơ, tác nhân gây bệnh, chẩn đoán bệnh, và biện pháp phòng trị bệnh. Đây sẽ là nguồn thông tin hữu ích cho các nhà nghiên cứu quan tâm đến AHPND cũng như khuyến khích các nhà khoa học tiếp tục nghiên cứu để góp phần ngăn ngừa, giảm thiểu ảnh hưởng của AHPND đối với nghề nuôi tôm nước lợ.
