Microbiota of Procellariiform

This study characterises the microbial composition Procellariiform seabirds and examines the influence of stomach oils on the microbial community using q16S rRNA pyrosequencing. The results indicated that Procellariiform seabirds harbour a highly diverse community of microbes, dominated by three phyla; Firmicutes, Proteobacteria and Bacteroidetes and that a high level of dissimilarity exists between all three species. A Significant differences were observed when comparing the oil producing and non-oil producing seabirds. In addition, negative correlations were observed by a Pearsons Correlation network between stomach oil producing (FP and STS) and non-stomach oil producing (CDP) Procellariiformes.

本研究对鹱形目（Procellariiformes）海鸟的微生物群落组成进行了表征，并借助定量16S rRNA焦磷酸测序技术探究了胃油对其微生物群落的影响。研究结果显示，鹱形目海鸟拥有高度多样的微生物群落，其优势菌门为厚壁菌门（Firmicutes）、变形菌门（Proteobacteria）和拟杆菌门（Bacteroidetes），且三个受试物种间的微生物群落差异程度极高。对比产胃油与非产胃油海鸟的微生物群落时，可观察到显著差异。此外，通过皮尔逊相关网络分析发现，产胃油类鹱形目（FP与STS）与非产胃油类鹱形目（CDP）之间存在负相关关系。
