在对湖北省洪湖常见鲤鱼黏液虫的调查中，收集到一种黏液虫，根据中国早前的描述，鉴定为黏液虫。然而，该物种的小亚基核糖体DNA与m的相似性仅为90%。dispar，代替matchingM。musselius100 %的身份。为了解决这一明显的分类学冲突，m。对来自中国的不公平报道进行了调查。在这里遇到的和在中国早期报告中遇到的物种都携带孢子，明显比m。disparin欧洲。在本研究中，粘液包膜粘附在许多新鲜孢子的后部，并被观察到扩大和包围孢子。这种结构从未报道过在新鲜孢子中发现。dispar。组织学显示鳃丝内血管外疟原虫与鳃丝的软骨线密切接触，这与m的疟原虫形成对比。在鳃丝的动脉中发育出差异丝。在系统发育上，现在的物种与m不同。相反，与m组成了姐妹组。musseliusae。这里提供的数据使我们得出结论，该物种分离了isM。之前关于m。对中国的诋毁是没有根据的。
During a survey of myxozoan parasites of common carpCyprinus carpioin Honghu Lake, Hubei Province, China, a parasite was collected that was identified asMyxobolus disparbased on an earlier description from China. However, the small subunit ribosomal DNA of this species shared only 90 % similarity withM. dispar, instead matchingM. musseliusaewith 100 % identity. To resolve this apparent taxonomic conflict, the validity ofM. disparreported from China was investigated. The species encountered here and in the earlier report from China both bear spores that are notably smaller than those ofM. disparin Europe. In the present study, a mucous envelope was adhered to the posterior of many fresh spores and was observed to expand and surround the spore. This structure has never been reported from fresh spores ofM. dispar. Histology showed extravascular plasmodia in the gill filaments in close contact with the cartilaginous ray of the filament, which contrasts with the plasmodia ofM. disparwhich develop in the arteries of the gill filaments. Phylogenetically, the current species is distinct fromM. dispar, instead forming a sister group withM. musseliusae. The data presented here allow us to conclude that the species isolated isM. musseliusaeand that prior reports ofM. disparin China are unsubstantiated.
