Abstract

印度特里普拉邦主要鲤鱼养殖场爆发病原菌的鉴定与分析。
目的:本研究的目的是调查印度特里普拉(Tripura)养殖系统中印度主要鲤鱼的细菌性疾病暴发,并确定与这些暴发相关的细菌种类。方法:在特里普拉邦的8个区进行了为期3年的监测,期间记录了9起细菌性疾病暴发。采用表型分析、分子分析(16S核糖体RNA基因)和系统发育分析等方法,对从病鲤中分离的14株细菌进行了鉴定。进行体外致病性研究以评估分离细菌的潜在致病性。结果:所选分离菌株初步鉴定为气单胞菌属(9株)、不动杆菌属(1株)、柠檬酸杆菌属(3株)和假单胞菌属(1株)。分子和系统发育分析证实了分离细菌的种类,包括江氏气单胞菌(菌株COF_AHE09和COF_AHE61)、维罗氏气单胞菌(菌株COF_AHE13、COF_AHE52、COF_AHE55、COF_AHE56和COF_AHE62)、嗜水气单胞菌(菌株COF_AHE51和COF_AHE58)、皮氏不动杆菌(菌株COF_AHE14)、弗氏柠檬酸杆菌(菌株COF_AHE20、COF_AHE57和COF_AHE59)和铜绿假单胞菌(菌株COF_AHE54)。病鱼表现为嗜睡、皮肤出血、溃疡、翅尾腐烂、突出眼、腹部肿胀、鳞片脱落、皮肤变色等行为和临床表现,提示细菌性败血症。体外致病性研究强调了这些细菌在疾病发展中的潜在作用,特别是在环境胁迫下。结论:本研究为了解与特里普拉邦养殖系统中印度主要鲤鱼细菌性疾病暴发相关的细菌物种多样性提供了有价值的见解。这是第一次全面的调查,有助于我们了解印度主要鲤鱼的细菌感染。

期刊介绍: The Journal of Aquatic Animal Health serves the international community of scientists and culturists concerned with the health of aquatic organisms. It carries research papers on the causes, effects, treatments, and prevention of diseases of marine and freshwater organisms, particularly fish and shellfish. In addition, it contains papers that describe biochemical and physiological investigations into fish health that relate to assessing the impacts of both environmental and pathogenic features.
