Biogeographical study on nematodes parasitic in endemic rodents of Indonesia.

从线虫与寄主的扩散和共同进化的角度，基于形态和DNA核苷酸序列分析，对寄生在印度支那群岛上的线虫进行了研究。在苏拉威西岛新发现的特有虫种中发现5种吸虫，其中包括2新亚属。同时，在同岛的老特有种中没有发现丝虫种，而是发现了异形科的一个新属。DNA测序结果表明，该菌株的DNA序列分析是成功的。来自苏拉威西岛。系统发育分析表明，它们在基地附近与该属的欧亚代表有分歧，但与爪哇和苏门答腊岛的Syphacia Muris形成相同的分支，表明它们是随着新的地方性小鼠的扩散而来到苏拉威西的。

Nematodes parasitic in murids on Indoensian islands were studied based on morphology and DNA nucleotide sequence analysis from the viewpoint of dispersal and coevolution with their hosts. Five species of Syphacia pinworms including 2 new subgenera were found from the new endemic murids of Sulawesi Island. Meanwhile, no Syphacia species was observed in the old endemic murids of the same island, but instead a new genus of Heterakidae was demonstrated. DNA sequence analysis was successful for Syphacia spp. from Sulawesi Island. Phylogenetic analysis revealed that these Syphacia had diverged near the base with Eurasian representatives of the genus, but formed same clade with Syphacia muris of Java and Sumatra, suggesting that they came to Sulawesi with the dispersal of new endemic murids.
