凡纳滨对虾急性肝胰腺坏死综合征研究进展

摘要

2009年以来,急性肝胰腺坏死综合征(AHPNS)使得亚洲对虾产量大幅下降,给亚洲养虾业带来了巨大的经济损失,我国以凡纳滨对虾养殖为主的对虾养殖业亦受到冲击.AHPNS 是由细菌感染引起的,病原菌通过效应蛋白PirA与PirB产生毒力,病虾消化器官颜色苍白,肝胰腺萎缩,空肠空胃,发病1 d~3 d内病死率达到100%.目前对于AHPNS的致病机制尚未研究清楚,尚无有效的防治手段.论文对凡纳滨对虾急性肝胰腺坏死综合征的流行病学、病理学、病原学、毒力因子、检测技术和防控手段等进行了综述.%Since 2009,AHPNS has cost huge economic losses to Asian shrimp culture industry with produc-tion fell sharply,and crashed China shrimp culture industry,especiall Litopenaeus vannamei breeding.AH-PNS is caused by bacterial infection,pathogens produce virulence through the effector protein PirA and PirB.Typical symptoms of AHPNS-infected shrimp are pale and atrophied hepatopancreas,and an empty stomach and midgut.When AHPNS broke out,the mortality could reach 100% within 1 to 3 days.At pres-ent,the pathogenesis of AHPNS has not been studied clearly,there is no effective means of prevention and treatment reported.Based on published journal articles,this paper reviewed the progress on epidemiology and pathology,pathogens,pathogenesis,detection technology,the prevention and control technology for AHPNS in L.vanmamei.
