摘要

The first report of Asian fish tapeworm (AFT), Schyzocotyle acheilognathi (Yamaguti, 1934) Brabec, Waeschenbach, Scholz, Littlewood and Kuchta, 2015, is provided for New York State. This finding resulted from a long-term fish parasite survey in various water bodies in Otsego County in central-east New York that took place during 2008-2018. In total, 1,637 individual fish representing 44 species were examined for AFT, with 4 (9%) of the 44 species of fish infected with S. acheilognathi. These 4 species were all cyprinids: Notemigonus crysoleucas (golden shiner), Notropis heterodon (blackchin shiner), Pimephales promelas (fathead minnow), and Semotilus atromaculatus (creek chub). Among these host species, the prevalence of Schyzocotyle acheilognathi was highest in Notemigonus crysoleucas, with 19 (15.7%) of 121 fishes infected. The infection in Notropis heterodon constitutes a new host record for S. acheilognathi. The observed occurrence of S. acheilognathi only in cyprinid species was generally consistent with previously reported infection patterns for this cestode, but we note that AFT was absent from multiple fish species in our survey that had elsewhere been reported as hosts. The source of AFT for water bodies in Otsego County, New York is unknown, but bait-bucket introduction of infected Notemigonus crysoleucas is considered a possible explanation. This study contributes to a growing body of molecular data for this highly invasive tapeworm by providing sequence data for 2 markers (large ribosomal subunit, 28S, and cytochrome c oxidase I) for 6 specimens.

Acheilognathi。这4种均为胞质胞质：Notemigonus crysoleucas（金色蝾螈），Notropis viderodon（Blackchin Shiner），Pimephales Promelas（Fathead Minnow）和Semotilus Atromaculatus（Creek Chub）。在这些宿主物种中，谢卓洛尼单抗的患病率在Notemigonus Crysolecas中最高，191个鱼类的121条鱼类中有19个（15.7％）。 Notropis Heterodon的感染构成了S. Acheilognathi的新主机记录。仅在脱鲤酸物种中观察到的S.Hapeilognathi的发生通常与先前报道的这种Cestode的感染模式一致，但我们注意到我们在我们的调查中没有多种鱼类在其他地方被报告为主。纽约Otsego县的船尾水尸体来源是未知的，但诱饵桶引入感染的Notemigonus crysoleucas被认为是可能的解释。该研究通过为2个标记（大核科亚基，28s和细胞色素C氧化酶I）提供6个标记，有助于这种高度侵袭性绦虫的分子数据的生长体系。
