鸟类代表了一个多样化和进化成功的谱系，在世界各地占据了广泛的生态位。像所有脊椎动物一样，鸟类的肠道中有不同的微生物群落，这些微生物群落在为宿主提供营养和保护病原体方面发挥着重要作用。尽管许多研究已经调查了鸟类肠道中特定微生物的作用，但没有人试图统一先前基于序列的研究结果，以检查塑造鸟类肠道微生物群的整体因素。在这项研究中，我们首次对禽类肠道微生物群进行了荟萃分析，使用了从一系列公开的克隆文库和扩增子焦焦测序数据中获得的16S rRNA基因序列。我们调查了群落成员和结构，并探讨了一些影响其他脊椎动物肠道微生物群的关键生物学因素的作用，如宿主系统发育、肠道内的位置、饮食和与人类的关系。我们的结果表明，在鸟类研究中，微生物群显示出与哺乳动物相似的门水平组成。宿主鸟类是决定群落组成的最重要因素，尽管采样地点、饮食和圈养状况也有影响。这些分析提供了对鸟类微生物群组成的第一个综合观察，并为该领域的未来研究奠定了基础。
Birds represent a diverse and evolutionarily successful lineage, occupying a wide range of niches throughout the world. Like all vertebrates, avians harbor diverse communities of microorganisms within their guts, which collectively fulfill important roles in providing the host with nutrition and protection from pathogens. Although many studies have investigated the role of particular microbes in the guts of avian species, there has been no attempt to unify the results of previous, sequence-based studies to examine the factors that shape the avian gut microbiota as a whole. In this study, we present the first meta-analysis of the avian gut microbiota, using 16S rRNA gene sequences obtained from a range of publicly available clone-library and amplicon pyrosequencing data. We investigate community membership and structure, as well as probe the roles of some of the key biological factors that influence the gut microbiota of other vertebrates, such as host phylogeny, location within the gut, diet, and association with humans. Our results indicate that, across avian studies, the microbiota demonstrates a similar phylum-level composition to that of mammals. Host bird species is the most important factor in determining community composition, although sampling site, diet, and captivity status also contribute. These analyses provide a first integrated look at the composition of the avian microbiota, and serve as a foundation for future studies in this area.
