The consumption of fish and shellfish worldwide is steadily increasing, and tuna is a particularly valuable fish species. However, infection caused by spp. is causing problems in many fish including the Pacific bluefin tuna (), and there is much controversy about the association of these infections with foodborne disease. In this study, using haematological and histological analyses of the blood and internal organs (liver, spleen, kidney, heart, stomach, intestine, gill, and muscle) of Pacific bluefin tuna cultured in South Korea, infection with Myxosporea was first identified, and molecular biological analysis was conducted. In this study, was finally identified. The Pacific bluefin tunas analysed in this study did not show any gross pathology lesions, such as visible cysts and/or myoliquefaction, of infection with this species. The histological analytical results can provide guidelines for the identification of . In the case of -induced infection, unlike other countries, such as Japan, there have been no reports in South Korea, and this study is the first to detect infection in Pacific bluefin tuna cultured in South Korea. The correlation between and food poisoning is not yet clear, however, it is thought that continuous observation of its infection is necessary.
全球范围内鱼类和贝类的消费量在稳步增长，金枪鱼是一种特别有价值的鱼类品种。然而，由[某菌属]引起的感染正在给包括太平洋蓝鳍金枪鱼（[具体学名]）在内的许多鱼类带来问题，并且这些感染与食源性疾病的关联存在诸多争议。在本研究中，通过对韩国养殖的太平洋蓝鳍金枪鱼的血液和内部器官（肝脏、脾脏、肾脏、心脏、胃、肠道、鳃和肌肉）进行血液学和组织学分析，首次鉴定出粘孢子虫感染，并进行了分子生物学分析。在本研究中，最终鉴定出了[具体菌种]。本研究中分析的太平洋蓝鳍金枪鱼未表现出该物种感染的任何肉眼可见的病理病变，如可见囊肿和/或肌液化。组织学分析结果可为[具体菌种]的鉴定提供指导。在韩国，与其他国家如日本不同，尚未有关于[具体菌种]引起感染的报道，本研究是首次在韩国养殖的太平洋蓝鳍金枪鱼中检测到[具体菌种]感染。然而，[具体菌种]与食物中毒之间的相关性尚不清楚，不过，认为有必要对其感染情况进行持续观察。
