species are one of the top causative pathogens of mortality in various fisheries worldwide. Their role in zoonotic infections and increase in antibiotic-resistance has raised concerns and interests in many research fields. Similar to the studies investigating human clinical cases, there has been an increase in research examining the potential pathogenic role of the bacterium in aquaculture. Within the family, was lastest group to be differentiated from the group, and many studies focusing on the virulence of this species have since ensued. In Korea, only infections have been reported in aquaculture industries, and there have been no reports on economic losses incurred owing to infection. There has been a recent report investigating the pathogenicity and pathological changes caused by infection in a tilapia farm located in the Costa Rica. To the best of our knowledge, as ours is the first report of infection in a Nile tilapia () farm located in an Asian country, the pathogenicity of the bacterial strain was histopathologically compared to that of the past studies. As tilapia is one of the most globally consumed fish species, particularly throughout Asia, Europe, and America, an epidemiological study regarding the disease distribution is necessary for the control and prevention of the disease. Here, we report the first mass mortality case caused by infection in a Nile tilapia farm located in Korea; the bacterial strain responsible was isolated, characterized, and pathologically analyzed.
[细菌名称]是全球各种渔业中导致死亡的主要病原体之一。它们在人畜共患感染中的作用以及抗生素耐药性的增加引起了许多研究领域的关注和兴趣。与调查人类临床病例的研究类似，研究该细菌在水产养殖中潜在致病作用的研究也有所增加。在[细菌所属菌属]家族中，[细菌名称]是最后一个从[另一细菌组]中分化出来的群体，自那以后，许多研究都集中在该物种的毒力上。在韩国，水产养殖业仅报告了[细菌名称]感染病例，尚未有因[细菌名称]感染造成经济损失的报告。最近有一份报告调查了哥斯达黎加一个罗非鱼养殖场中[细菌名称]感染引起的致病性和病理变化。据我们所知，由于我们的报告是亚洲国家尼罗罗非鱼（[罗非鱼学名]）养殖场中[细菌名称]感染的首次报告，因此对该菌株的致病性进行了组织病理学比较，并与以往研究进行了对比。由于罗非鱼是全球消费最多的鱼类品种之一，尤其是在亚洲、欧洲和美洲，因此有必要进行关于疾病分布的流行病学研究，以控制和预防该疾病。在此，我们报告韩国一个尼罗罗非鱼养殖场首次发生的由[细菌名称]感染引起的大规模死亡病例；对致病菌株进行了分离、鉴定和病理分析。
