We used high-throughput DNA sequencing to explore bacterial communities of three species of Oropyslla fleas [Oropsylla hirsuta (Baker), Oropsylla montana (Baker), and Oropsylla tuberculata cynomuris (Jellison)] and detected seven bacterial lineages related to known insect symbionts. No significant co-occurrence patterns were detected among bacterial lineages, but relative abundance data suggest that the two most common lineages (Bartonella and Rickettsiales) interact negatively. Furthermore, presence of these two lineages significantly reduced bacterial diversity within fleas.
我们使用高通量 DNA 测序技术探索了三种 Oropyslla 跳蚤（Oropsylla hirsuta（Baker）、Oropsylla montana（Baker）和 Oropsylla tuberculata cynomuris（Jellison））的细菌群落，并检测到与已知昆虫共生体相关的 7 种细菌谱系。细菌谱系之间未检测到显著的共同发生模式，但相对丰度数据表明两种最常见的谱系（巴尔通体和立克次氏体目）存在负相互作用。此外，这两种谱系的存在显著降低了跳蚤体内的细菌多样性。
