The tick (Acari, Ixodidae) is an obligatory blood-feeding ectoparasite of the giant panda and is also a vector for transmission of pathogenic microorganisms. In this study, the complete mitochondrial genome of this tick was sequenced through Illumina sequencing technology. The genome was 14,699 bp in length and encoded 37 genes including 13 protein-coding genes, 22 transfer RNAs and two ribosomal RNAs. Phylogeny revealed that three isolates of , regardless of host origins and locations, clustered together and formed a monophyletic relationship with , supporting their species validity among the genus . These cumulative mitochondrial DNA data provides insights into phylogenetic studies among ticks.
蜱虫（蜱螨亚纲，硬蜱科）是大熊猫的专性吸血外寄生虫，也是致病微生物传播的媒介。在本研究中，通过Illumina测序技术对该蜱虫的完整线粒体基因组进行了测序。该基因组长度为14,699bp，编码37个基因，包括13个蛋白质编码基因、22个转运RNA和两个核糖体RNA。系统发育分析表明，无论宿主来源和地理位置如何，三种分离株聚集在一起，并与[某物种]形成单系关系，支持它们在该属中的物种有效性。这些累积的线粒体DNA数据为蜱虫的系统发育研究提供了见解。
