Thelohanellus kitauei (Myxobolidae) infects cyprinid fish. The evolution of species derived from common ancestors results in the sharing of biological features. To reveal the origin of T. kitauei biological features, the correlation between phylogeny and biological features of Myxobolidae was investigated by Bayesian inference tree and Bayesian tip association significance testing. The results demonstrated that host specificity and infection site tropism were correlated with the phylogeny of Myxobolidae, and that the biological features of T. kitauei originated from the ancient Myxobolidae as exhibited by the non-specific infection site tropism and the ability to infect cyprinids.
棘隙虫（粘体动物门）感染鲤科鱼类。源自共同祖先的物种进化导致生物特征的共享。为了揭示棘隙虫生物特征的起源，通过贝叶斯推断树和贝叶斯尖端关联显著性检验，研究了粘体动物门的系统发育与生物特征之间的相关性。结果表明，宿主特异性和感染部位趋向性与粘体动物门的系统发育相关，棘隙虫的生物特征起源于古老的粘体动物门，表现为非特异性的感染部位趋向性和感染鲤科鱼类的能力。
