洪湖碘泡虫n.在湖北洪湖调查异育银鲫粘孢子虫时，从异育银鲫Carassiusauratusgibelio（Bloch）体内分离到一种粘孢子虫。其特征是在宿主咽部存在直径为5-12 mm的圆形原质团。M.红虎龙的正面观为梨形，前尖后钝圆，长16.9 ± 0.5（15.1-19.5）μ m，宽10.4 ± 0.4（9.0-11.3）μ m，厚8.4 ± 0.4（7.9-9.1）μ m。两个极蒴果为梨形，稍不相等，较大的极蒴果为8.4 +/- 0.4（7.6-10.2）μ m x 3.9 +/- 0.2（3.0-4.5）μ m，较小的极蒴果为7.9 +/- 0.2（7.0-9.3）μ m x 3.7 +/- 0.3（2.8-4.1）μ m。极丝盘绕七到八圈。形态学和DNA序列分析表明，M.洪湖;洪湖sp.与已报道的碘泡虫属其他种不同。系统发育分析将M.洪湖;洪湖sp.在一个分支的鳃感染粘细菌。
Myxobolus honghuensis n. sp. is described from allogynogenetic gibel carp Carassius auratus gibelio (Bloch), during a survey of myxosporean parasites in Honghu Lake, Hubei Province, China. It is characterized by the presence of round plasmodia of 5-12 mm in diameter in the pharynx of host. Mature spores of M. honghuensis were pyriform in frontal view and anterior pointed with bluntly round posterior, they measured 16.9 +/- 0.5 (15.1-19.5) mu m long, 10.4 +/- 0.4 (9.0-11.3) mu m wide, and 8.4 +/- 0.4 (7.9-9.1) mu m thick. Two polar capsules were pyriform and slightly unequal with larger polar capsule 8.4 +/- 0.4 (7.6-10.2) mu m x 3.9 +/- 0.2 (3.0-4.5) mu m and smaller capsule 7.9 +/- 0.2 (7.0-9.3) mu m x 3.7 +/- 0.3 (2.8-4.1) mu m. Polar filaments coiled with seven to eight turns. Both morphology and DNA sequence data revealed that M. honghuensis n. sp. was distinct from other described Myxobolus species. Phylogenetic analysis placed M. honghuensis n. sp. in a clade of gill-infecting myxobolids.
