Abstract

Scuticociliates are dangerous parasitic pathogens causing systemic tissue destruction and high mortality in marine fish worldwide. In this study, the first identification of (Ciliophora, Scuticociliatida) from cultured turbot () larvae using mitochondrial cytochrome c oxidase 1 (1) gene sequence as well as species-specific primers was reported. The mean prevalence values of infected fish were calculated, and partial sequencing obtained from the mitochondrial 1 gene region was also compared with isolates registered in the Genbank database. The sequence comparison showed 93.00% identity to , and the parasite has also been deposited in the GenBank database. This study is the first case of infection in Turkish marine aquaculture, contributing to the systematics and molecular epidemiology of scuticociliate in Turkey.

摘要

盾纤毛虫是危险的寄生性病原体,在全球范围内会导致海水鱼类的系统性组织破坏和高死亡率。在本研究中,报告了首次利用线粒体细胞色素c氧化酶1(CO1)基因序列以及物种特异性引物,从养殖大菱鲆(Scophthalmus maximus)幼体中鉴定出(纤毛虫纲,盾纤目)。计算了感染鱼的平均患病率,并将从线粒体CO1基因区域获得的部分序列与Genbank数据库中登记的分离株进行了比较。序列比较显示与[某物种]有93.00%的同一性,该寄生虫也已存入GenBank数据库。本研究是土耳其海水养殖中[该寄生虫名称]感染的首例,为土耳其盾纤毛虫的系统学和分子流行病学研究做出了贡献。
