摘要

根据巴西北部帕拉州维塞乌市采集的Pacuma蟾蜍鱼Batrachoides surinamensis肌肉组织标本，描述了一种新的黏液动物Kudoa viseuensis n. sp.(黏液孢子目:多阀目)。对60份苏里南芽孢杆菌标本进行了检测，其中52份(86%)呈白色假囊，假囊内含有大量圆形孢子(长7.2±0.2 μm，宽5.2±0.2 μm)。孢子有4个极性蒴果，大小相等，顶端为1.8±0.2 μm × 1.3±0.1 μm，侧面为2.7±0.2 μm × 1.3±0.1 μm。获得小亚基核糖体RNA基因的部分序列(1400 bps)，并存入GenBank(访问号:MK256272)。与其他库多亚种的形态和分子资料的比较支持了亚马逊地区混合孢子虫新种的描述，这里命名为Kudoa viseuensis n. sp。

Morphological and Molecular Characteristics of Kudoa viseuensis n. sp. (Myxosporea: Multivalvulida), Found in the Muscle of Batrachoides surinamensis (Teleostei: Batrachoididae) in the Brazilian Amazon Region

A new species of myxozoan, Kudoa viseuensis n. sp. (Myxosporea: Multivalvulida), is described based on specimens extracted from the musculature of the Pacuma toadfish, Batrachoides surinamensis, collected in the municipality of Viseu, in the northern Brazilian state of Para. A total of 60 specimens of B. surinamensis were examined, of which 52 (86%) presented whitish pseudocysts containing numerous rounded spores (7.2±0.2 μm in length and 5.2±0.2 μm in width). These spores have four polar capsules of equal size, measuring 1.8±0.2 μm x 1.3±0.1 μm in the apical view, and 2.7±0.2 μm x 1.3±0.1 μm in the lateral view. A partial sequence (1400 bps) of the small subunit ribosomal RNA gene was obtained and deposited in GenBank (access number: MK256272). The comparison of the morphological and molecular data with those of other Kudoa species supported the description of a new species of mixosporean from the Amazon region, which is denominated here as Kudoa viseuensis n. sp.

期刊介绍： Acta Protozoologica - International Journal on Protistology - is a quarterly journal that publishes current and comprehensive, experimental, and theoretical contributions across the breadth of protistology, and cell biology of Eukaryote microorganisms including: behaviour, biochemistry and molecular biology, development, ecology, genetics, parasitology, physiology, photobiology, systematics and phylogeny, and ultrastructure. It publishes original research reports, critical reviews of current research written by invited experts in the field, short communications, book reviews, and letters to the Editor.
