Biogeographical study on nematodes parasitic in endemic rodents of Indonesia.

从散布和与寄主共同进化的角度，对印度尼西亚群岛鼠体内寄生线虫进行了形态学和DNA序列分析。在苏拉威西岛新特有虫群中发现梅毒蛲虫5种，包括2个新亚属。与此同时，在同一岛屿的老特有种群中未发现合欢属，而是发现了一个新的合欢科属。对苏拉威西岛的梅毒属进行了成功的DNA序列分析。系统发育分析显示，这些Syphacia与该属的欧亚代表在接近基部的地方发生了分化，但与爪哇和苏门答腊的Syphacia muris形成了相同的分支，这表明它们是随着新的地方性murids的扩散而来到苏拉威西岛的。

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.
