ABSTRACT: Infections with microsporidian parasites are described in skeletal muscle of burbot Lota lota from Lake Haukivesi, Finland. Infected myocytes contained spores within sporophorous vesicles (SPVs) in contact with host cell cytoplasm, similar to Pleistophora ladogensis in L. lota and smelt Osmerus eperlanus in western Russia and northern Germany. Analysis of small subunit ribosomal RNA (SSU rRNA) gene sequences indicated identity with Myosporidium spraguei in burbot and pike-perch from this lake. The latter is considered a junior synonym of P. ladogensis. Phylogenetic analysis of SSU rRNA sequences resolved the burbot parasite apart from a clade containing the type species P. typicalis, but together with M. merluccius. The parasite is renamed Myosporidium ladogensis (Voronin, 1978) n. comb. Networks of tubular appendages arising from developing meronts and SPVs were associated with degradation of host cell cytoplasm.

拉多犬肌孢子虫 梳。来自芬兰的Burbot Lota lota：精细的结构和微孢子虫分类。

摘要：来自芬兰Haukivesi湖的Burot Lota lota骨骼肌中描述了微孢子虫寄生虫的感染。感染的心肌细胞在孢子囊泡（SPV）中包含与宿主细胞质接触的孢子，类似于L. lota中的Pleistophora ladogensis，在俄罗斯西部和德国北部闻到了Osmerus eperlanus。对小亚基核糖体RNA（SSU rRNA）基因序列的分析表明，与该湖的梭子蟹和梭鲈中的孢子菌是相同的。后者被认为是拉多犬假单胞菌的初级同义词。对SSU rRNA序列的系统发育分析解析了梭虫寄生虫，除了包含类型物种的进化枝外。P.典型的，但是与M. merluccius一起。将该寄生虫重命名为拉多斯肌孢子菌（Voronin，1978）。梳。发育中的鱼尾和SPV引起的管状附件的网络与宿主细胞质的降解有关。
