关于培养的Whiteleg虾(PenaeusVannamei)的报告是由2011年的霹雳州培训卫队(Nafish)于2011年首次接受霹雳州,显示出白色粪便和缓慢死亡的迹象,导致严重死亡率。后来,同年9月,马来西亚虾农民协会(MSFA)向渔业部(DOF)严重死亡,几乎所有白白马来西亚虾农场。然后通过NaFish进行疾病诊断的虾采样。细菌学和组织病理学检查分别揭示了肝癌上皮细胞的V.副溶解和巨大脱落的分离。随后将该疾病鉴定为急性肝癌坏死疾病(AHPND)。从我们的3年度的研究中,2011年,2012年和2013年,AHPND的年度流行率分别为50%,26%和73%。目前,AHPND仍然存在于马来西亚,但普遍存在较低。研究了与该疾病相关的危险因素,然而,分析的环境和管理数据分析不确定,将任何一个参数直接与疾病联系起来。为了帮助确保早期检测AHPND,进行了对“肠道记分卡的实验观察研究,并且通过PCR和组织病理学证实了这一点。验证该技术尚未开展以确保其可靠性。 We also examined the potential use of some commercial products such as probiotics and disinfectants available in the market but unfortunately results showed that they were not effective in controlling AHPND. Control measures applied by the farmers such as the use of probiotics were also verified but data generated likewise appeared to be inconclusive. On the contrary, our preliminary study on the antibacterial property of the plant extracts, i.e. betel and lemongrass, incorporated in the feed showed some prophylactic and chemotherapeutic potential against AHPND. However, comprehensive in vitro and in vivo trials are still currently being undertaken to elucidate its efficacy and practical applications. To ensure the shrimp industry s sustainability in Malaysia, results of our ongoing and future studies aimed at preventing and controlling unwarranted outbreaks of AHPND and other emerging transboundary diseases of penaeid shrimps will be continually disseminated to shrimp farmers and pertinent stakeholders.
