Abstract

Ticks are important vectors of various pathogens that cause infectious diseases in humans. Endosymbiotic bacteria have been explored as targets for tick and tick-borne disease control. However, the tick bacterial community on Hainan Island, which is the largest tropical island in China and has an environment favourable to ticks, has not yet been studied. In this study, we surveyed the bacterial community of ticks collected from grass in one village in Haikou. A total of 20 ticks were morphologically and molecularly identified as Haemaphysalis spp. The tick bacterial 16S rRNA hypervariable region amplicon libraries were sequenced on an Illumina MiSeq platform. A total of 10 possible bacterial genera were detected, indicating a low-diversity bacterial community profile. The dominant bacterial genus, Massilia, accounted for 97.85% of the population. Some other bacterial genera, including Arsenophonus and Pseudomonas, have been reported to play a role in tick development and tick-borne pathogen transmission in other tick species. Overall, the study highlights the first descriptive understanding of the tick bacterial community on Hainan Island and provides a basis for deciphering the interactions between the tick microbiome and tick-borne pathogens.

海南岛野外采集蜱血蜱内共生细菌群落多样性分析。
蜱是引起人类传染病的各种病原体的重要媒介。内共生细菌已被探索作为蜱和蜱传疾病控制的目标。然而,作为中国最大的热带岛屿,海南岛具有适宜蜱虫生存的环境,其蜱虫细菌群落尚未得到研究。本研究对海口市某村采集的草地上蜱虫的细菌群落进行了调查。在Illumina MiSeq平台上对蜱属细菌16S rRNA高变区扩增子文库进行测序。共检测到10个可能的细菌属,表明细菌群落多样性较低。优势菌属Massilia占总数的97.85%。据报道,其他一些细菌属,包括Arsenophonus和Pseudomonas,在其他蜱类的蜱发育和蜱传病原体传播中发挥作用。总体而言,该研究突出了对海南岛蜱虫细菌群落的首次描述性认识,并为破译蜱虫微生物群与蜱传病原体之间的相互作用提供了基础。

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
