Herein, the morphological and genetic features of the larval specimens of anisakine nematode, isolated from Ylistrum japonicum (Pectinidae) collected from Japanese waters, were examined. Although the specimens were identified as members of the genus Sulcascaris, they were genetically divergent from Sulcascaris sulcata, which is currently the only member of the genus. The present study highlights the possibility that the Sulcascaris population inhabiting Japanese waters represents a unique taxonomic position within the genus Sulcascaris. Additionally, given that many pectinid scallops have been reported as intermediate host of S. sulcata, the present study implies that pectinid scallops may also represent the primary intermediate hosts for the present Japanese Sulcascaris species. Because S. sulcata infections can cause discoloration in the meat of scallops, regular monitoring of the prevalence and intensity of Sulcascaris infections is required to predict the impact of the infections on the market.
本文研究了采自日本水域的日本拟庸鲽（扇贝科）体内分离出的棘头虫幼虫的形态和遗传特征。尽管这些标本被鉴定为苏斯卡里斯属的成员，但它们在遗传上与目前唯一的苏卡里斯属成员苏卡里斯·苏卡特（Sulcascaris sulcata）存在差异。本研究强调了栖息在日本水域的苏卡里斯种群可能代表了苏卡里斯属内一个独特的分类地位。此外，由于许多扇贝科贝类已被报道为苏卡里斯·苏卡特的中间宿主，本研究表明，扇贝科贝类也可能是目前日本苏卡里斯属物种的主要中间宿主。由于苏卡里斯·苏卡特感染会导致扇贝肉变色，因此需要定期监测苏卡里斯感染的流行率和强度，以预测感染对市场的影响。
