摘要

- 2017年，在日本爱知县的金鱼批发市场发现了一条皮肤出现肿瘤样巨大病变的鲫鱼。病变直径2 ~ 4mm，部分可见出血。显微镜观察显示有大量黏液孢子，单极蒴果。孢子长17.1±1.0 μ m(平均±SD)，宽6.1±0.7 μ m。18S rRNA基因部分序列与telohanellus testudineus完全相同。这是首次在金鱼中发现鼠尾绦虫。

First Report of Thelohanellus testudineus (Myxosporea) from the Skin of Goldfish Carassius auratus in Japan

― In 2017, one individual of goldfish Carassius auratus which had tumor-like massive lesions in the skin was found in a goldfish wholesale market in Aichi Prefecture, Japan. The lesions were 2–4 mm in diameter and hemorrhage was observed in some of them. Microscopic observation revealed numerous myxospores with a single polar capsule. The spores were 17.1 ± 1.0 μ m (mean ± SD) long, and 6.1 ± 0.7 μ m wide. The partial sequence of 18S rRNA gene was 100% identical to that of Thelohanellus testudineus . This is the first report of T. testudineus in goldfish.
