摘要/Abstract

摘要： 本研究聚焦于亚洲璃眼蜱(Hyalomma asiaticum)雌性成蜱，深入探究其在不同吸血阶段以及完全饱血状态下，体内部分器官的菌群构成情况。通过分析吸血期对菌群丰度差异的影响，旨在获取雌性亚洲璃眼蜱体内菌群变化的关键数据，为相关研究提供数据参考。本研究运用Illumina Novaseq测序平台，针对亚洲璃眼蜱雌性在不同吸血阶段以及完全饱血状态下的多个器官(包括中肠、马氏管、卵巢、唾液腺)，开展16S rRNA V3 - V4区的高通量测序工作。通过对比分析，揭示亚洲璃眼蜱雌性在不同阶段以及完全饱血状态下各器官菌群的动态变化规律。随着亚洲璃眼蜱吸血进程的推进，其菌群多样性Shannon指数呈现出显著降低的趋势，从饥饿期的4.2±0.3下降至饱血期的1.8±0.2 (P<0.01)。在此过程中，变形菌门(Proteobacteria)逐渐成为绝对优势菌门，其相对丰度超过99%。对完全饱血器官的分析表明，弗朗西斯菌属(Francisella)在饱血卵巢中高度富集，相对丰度高达99.75%，且与中肠中的弗朗西斯菌属存在极显著差异(P<0.01)。此外，该菌属的丰度随吸血时间呈现出先上升后下降的趋势，具体表现为在吸血24 h时丰度为12.3%，至96 h时达到峰值89.7%，而在完全饱血期则降至75.3%。本研究结果充分揭示了亚洲璃眼蜱雌性在不同吸血阶段以及完全饱血状态下内部器官中菌群的复杂性和多样性特征。这一发现不仅丰富了人们对亚洲璃眼蜱相关菌群的认知，还为进一步深入理解亚洲璃眼蜱体内菌群与宿主之间的互作关系提供了重要的数据基础。

Abstract: This study focuses on female adult Hyalomma asiaticum, aiming to thoroughly investigate the microbial community composition in certain internal organs during different blood-feeding stages and the fully engorged state. By analyzing the impact of the blood-feeding period on the differences in microbial abundance, the key data on the changes in the microbial community within female H. asiaticum were obtained, which was used to provide a data reference for relevant research. In this study, the Illumina Novaseq sequencing platform was employed to conduct high-throughput sequencing of the 16S rRNA V3 - V4 region in female H. asiaticum at different blood-feeding stages and in multiple organs (including the midgut, Malpighian tubules, ovaries, and salivary glands) of fully engorged female H. asiaticum. Through comparative analysis, the dynamic changes in the microbial communities in female ticks at different stages and in the organs of fully engorged ticks were revealed. As the blood-feeding process of H. asiaticum progressed, the Shannon index of microbial community diversity showed a significant decreasing trend, dropping from 4.2±0.3 in the starved state to 1.8±0.2 in the fully engorged state (P<0.01). During this process, Proteobacteria gradually became the absolutely dominant phylum, with a relative abundance exceeding 99%. Analysis of the fully engorged organs indicated that Francisella was highly enriched in the engorged ovaries, with a relative abundance as high as 99.75%, and there was an extremely significant difference compared to Francisella in the midgut (P<0.01). In addition, the abundance of this genus exhibited a trend of first increasing and then decreasing with blood-feeding time. Specifically, the abundance was 12.3% at 24 h of blood-feeding, reached a peak of 89.7% at 96 h, and then decreased to 75.3% in the fully engorged state. The results of this study fully reveal the complexity and diversity of the microbial communities in the internal organs of female H. asiaticum at different blood-feeding stages and in the fully engorged state. This discovery not only enriches our understanding of the microbial communities associated with H. asiaticum but provides an important data foundation for further in-depth comprehension of the interactions between the microbial communities and the host within H. asiaticum adults.
