摘要

接收日期:修订日期:接受日期:在线发布日期:2017年7月4日2017年11月6日2018年1月24日2019年6月19日与自然海水温度下的养殖场相比,在温水池塘中进行鱼类养殖可以更好地生长,但温度的升高有利于细菌和鱼类疾病的发展。在这项研究中,在用发电厂的热水在池塘中饲养的欧洲鲈鱼(Dicentrarchus labrax)标本中,我们旨在表征细菌群落以及一些血清代谢和免疫参数,这些标本显示出弧菌病样疾病的症状。细菌学分析显示,粪便大肠菌群、铜绿假单胞菌、溶藻弧菌、酵母和霉菌受到了重要污染,而健康和患病标本的鱼类组织中的总需氧菌群和几种潜在致病菌均呈阳性,如溶藻弧菌,嗜水气单胞菌,多杀性巴氏杆菌,绿脓杆菌,普通变形杆菌和奇异变形杆菌。此外,hollisae Grimontia只存在于患病的鱼类组织中。患病鱼类的血清代谢参数,如天冬氨酸氨基转移酶、胆汁酸、肌酸激酶、尿酸、葡萄糖、球蛋白和钾通常会增加,尽管与健康样本相比,只有磷水平达到显著水平。关于鱼类的先天免疫,我们的结果显示,健康鱼类和患病鱼类在过氧化物酶、蛋白酶或抗蛋白酶活性方面没有统计学差异,而患病鱼类对鳗弧菌的杀菌活性显著降低。最后,病鱼血液中il1b、c3、dic和mpx的基因表达下调,而ighm的基因表达上调。©2018 PVJ。保留所有权利

Bacteriological, Metabolic and Immunological Evaluation of European sea Bass Reared in Ponds with Heated Water under a Natural Vibriosis-Like Outbreak
