笔者在江苏省溧阳某鲫养殖塘底泥采集的苏氏尾鳃蚓(Branchiura sowerbyi)中检测到一种放射孢子虫,经形态特征观察和比较分析,鉴定其隶属于棘放射孢子虫(Echinactinomyxon)类群.该放射孢子虫孢体呈圆柱形,长18.95μm(18.5~19.4μm),宽9.55μm;极囊长6.11μm(5.97~6.26),宽2.98μm(2.38~3.58);尾柄长161.2μm(161.2~167.16),宽3.24μm(2.98~3.58),孢体与尾柄的夹角约为160°.将其与国内外文献中已记述的放射孢子虫作比较研究,发现其在寄生宿主、形态大小、尾柄特征等方面有明显差异.本文描述的该类放射孢子虫为国内外首次报道.

There is a very high diversity of myxosporeans in China. Outbreaks of some myxosporan species have resulted in significant economic loss to the aquaculture industry. Despite this, little is known about the myxo-sporean life cycle. We describe a new Echinactinomyxon type collected from oligochaetes (Branchiura sowerbyi) that were isolated from a crucian carp (Carassius auratus gibelio) fry pond in Liyang City, Jiangsu Province in September, 2011. Two of the 200 B. sowerbyi (1%) we examined were found to release actinospores. The actino-spore possesses a barrel-shaped spore body and 3 caudal processes with four-branched tips. Spore body 8.95μm (18.5?19.4) long and 9.55μm wide. Sporoplasm cells not determined. Three pyriform polar capsules located at the apex, 6.11μm (5.97?6.26) long and 2.98μm (2.38?3.58) wide. Caudal processes originating just below the spore body, equal in size, straight, 161.2μm (161.2?167.16) long and 3.24μm (2.98?3.58) wide.
