ABSTRACT: A new myxobolid species, Myxobolus zaikae n. sp., was found in the connective tissue near the kidney and liver blood vessels of the common roach Rutilus rutilus, while fish myxosporean fauna were being investigated in Lake Baikal, Russia. The parasites were studied on the basis of spore morphology as well as with histological and molecular methods. Mature spores of M. zaikae n. sp. are round or ellipsoidal in the frontal view and lemon-shaped in the lateral view, measuring 11.37 ± 0.11 µm (10.2-14.0 µm) in length, 10.29 ± 0.10 µm (9.6-11.0 µm) in width, and 6.3 ± 0.08 µm (5.8-7.1 µm) in thickness (mean ± SD; n = 50). Polar capsules are equal and pyriform, measuring 4.5 ± 0.07 µm (3.4-5.2 µm) in length and 2.9 ± 0.03 µm (2.6-3.3 µm) in width. Polar capsules contained polar filaments coiled with 5 to 6 turns. Phylogenetic analysis showed that this newly described species clusters with other myxobolid species infecting the connective tissue of different organs from Palearctic cyprinid fish.

枣粘菌的形态，组织学和分子方面。贝加尔湖中的Rutilus rut​​ilus蟑螂的寄生虫

摘要：一种新的粘菌种，Myxobolus zaikae n。在常见的蟑螂Rutilus rut​​ilus的肾脏和肝脏血管附近的结缔组织中发现了一种细菌，而在俄罗斯贝加尔湖正在研究鱼类粘孢子菌群。根据孢子形态以及组织学和分子方法对寄生虫进行了研究。zaikae的成熟孢子。sp。正面为圆形或椭圆形，侧面为柠檬形，长度为11.37±0.11 µm（10.2-14.0 µm），宽度为10.29±0.10 µm（9.6-11.0 µm），尺寸为6.3±0.08 µm（厚度为5.8-7.1 µm）（平均值±标准偏差； n = 50）。极性囊相等且呈梨形，长度为4.5±0.07 µm（3.4-5.2 µm），宽度为2.9±0.03 µm（2.6-3.3 µm）。极性胶囊包含缠绕5至6圈的极性细丝。系统发育分析表明，该新近描述的物种与其他粘菌类物种聚集在一起，感染了古太平洋鲤鱼不同器官的结缔组织。
