The present study attempted sequencing the 18S rRNA gene of infecting the gill lamellae of carp, and compared its genetic homology and phylogenetic characteristics with 18S rRNA genes of other spp. The infected fish had up to 3 small, creamy white plasmodia per gill filament with 30-50 spores each. The spore size was 17.90 ± 0.70 × 7.40 ± 0.40 μm. The sporoplasm contained two large nuclei of size 0.57 ± 0.09 μm and no iodinophilous vacuole. The DNA sequence of was clustered phylogenetically with other spp. infecting the gills of cyprinids available in GenBank, which showed 77-87 % homogeneity. On the phylogenetic tree, (KC933944) was clustered with (HM991164) infecting the gill lamellae of silver carp, . The species most closely related to in GenBank was (AF507973) infecting the gill lamellae of big head carp, with 87 % homogeneity. This is the first report on molecular characterization of gill lamellae infecting
本研究尝试对感染鲤鱼鳃小片的[某种生物]的18S rRNA基因进行测序,并将其与其他[生物种类]的18S rRNA基因的遗传同源性和系统发育特征进行比较。受感染的鱼每根鳃丝上有多达3个小的乳白色孢原质团,每个孢原质团有30 - 50个孢子。孢子大小为17.90±0.70×7.40±0.40μm。孢质内有两个大小为0.57±0.09μm的大核,且无嗜碘泡。[某种生物]的DNA序列在系统发育上与GenBank中其他感染鲤科鱼类鳃的[生物种类]聚类,显示出77 - 87%的同源性。在系统发育树上,某种生物与感染鲢鱼鳃小片的某种生物聚类。GenBank中与[某种生物]关系最密切的物种是感染鳙鱼鳃小片的某种生物,同源性为87%。这是关于感染鳃小片的分子特征的首次报道
