In the present study, a new species of the genus species is described taxonomically in the mitochondrial genomic context. The parasite was found in a plateau zokor captured in a high-altitude area of Xiahe County of Gansu Province, China. The mitochondrial () genome length of this new species was 14,066 bp comprising 36 genes and 2 additional non-coding regions (SNR and LNR), without 8. The molecular phylogeny inferred by the cytochrome c oxidase subunit I gene (1) and the18S ribosomal RNA gene (18S rDNA) sequences showed that the parasite as a sister species to other spp. and was named sp. XH-2020. The phylogeny of the concatenated amino acid sequences of the 12 protein-coding genes (PCGs) showed sp. XH-2020 in the same cluster as and i confirming the 1 and 18S rDNA phylogenetic inference. In addition, the entire genome sequenced in this study represents the first in the order Moniliformida, providing molecular material for further study of the phylogeny of the class Archiacanthocephala. Moreover, the species of this class, use arthropods as intermediate hosts and mammals as definitive hosts and are agents of acanthocephaliasis, a zoonosis in humans. Therefore, this study not only expands the host range among potential wild animal hosts for Archiacanthocephalans which is of great ecological and evolutionary significance but also has important significance for the research of zoonotic parasitic diseases.
在本研究中,在线粒体基因组背景下对一个新物种进行了分类学描述。该寄生虫是在中国甘肃省夏河县高海拔地区捕获的一只高原鼢鼠体内发现的。这个新物种的线粒体()基因组长度为14,066 bp,包含36个基因和2个额外的非编码区(SNR和LNR),不含8。由细胞色素c氧化酶亚基I基因(1)和18S核糖体RNA基因(18S rDNA)序列推断的分子系统发育表明,该寄生虫是其他 spp.的姐妹物种,并被命名为 sp. XH - 2020。12个蛋白质编码基因(PCGs)的串联氨基酸序列的系统发育显示,sp. XH - 2020与 和 i 在同一簇中,证实了1和18S rDNA系统发育推断。此外,本研究中测序的整个 基因组代表了念珠棘头虫目(Moniliformida)中的首个基因组,为进一步研究古棘头虫纲(Archiacanthocephala)的系统发育提供了分子材料。而且,该纲的物种以节肢动物为中间宿主,以哺乳动物为终末宿主,是棘头虫病的病原体,一种人畜共患的人类疾病。因此,本研究不仅扩大了古棘头虫潜在野生动物宿主的范围,具有重要的生态和进化意义,而且对人畜共患寄生虫病的研究也具有重要意义。
