Abstract

Myxobolus zhaltsanovae n. sp., is described from the gills of gibel carp Carassius gibelio found during a survey of myxozoans from the watershed of Lake Baikal, Russia, based on morphological and molecular characterizations. Plasmodia of M. zhaltsanovae n. sp. develop extravascularly and measure 500-1000 μm long, 25-100 μm wide. The myxospore is circular to oval, measuring 13.23 ± 0.09 (11.3-14.8) µm (mean ± SD, range) in length, 10.19 ± 0.07 (9.1-11.4) µm in width, and 6.49 ± 0.12 (5.4-7.2) µm in thickness. Polar capsules are unequal and subspherical; measurements of polar capsules are: length 5.62 ± 0.06 (4.7-6.7), width 3.44 ± 0.04 (2.4-4.4) µm and length 3.42 ± 0.05 (2.5-4.1), width 1.94 ± 0.04 (1.3-3.3) µm. Phylogenetic analysis with the 18S rDNA gene shows M. zhaltsanovae n. sp. as a sister species of the subclade formed by M. musseliusae, M. tsangwuensis, and M. basilamellaris, which infect common carp Cyprinus carpio.

标题鲫鱼(鲤形目:鲤科)粘虫一新种(刺胞纲:粘虫目:粘虫科)。

在对俄罗斯贝加尔湖流域黏液动物调查中发现的异育银鲫(Carassius gibelio)的鳃部进行了形态学和分子特征的描述。疟原虫在血管外发育，长500 ~ 1000 μm，宽25 ~ 100 μm。黏液孢子呈圆形至椭圆形，长13.23±0.09(11.3-14.8)µm (mean±SD, range)，宽10.19±0.07(9.1-11.4)µm，厚6.49±0.12(5.4-7.2)µm。极性蒴果不等长和近球形;极性胶囊的测量值为:长5.62±0.06(4.7-6.7)，宽3.44±0.04(2.4-4.4)µm，长3.42±0.05(2.5-4.1)，宽1.94±0.04(1.3-3.3)µm。用18S rDNA基因进行系统发育分析表明，该菌是感染鲤鱼鲤(Cyprinus carpio)的musseliusae、M. tsangwuensis和M. basilamellaris组成的亚分支的姐妹种。
