“…Both Firmicutes and Bacteroidetes participate in the metabolic processes of the host, and Firmicutes can produce volatile fatty acids and other by-products from the metabolic process [ 46 ]. Bacteroidetes can degrade proteins, carbohydrates, and compounds in plant cell walls [ 47 ]. The Firmicutes/Bacteroidetes ratio was slightly increased in the G. duodenalis -positive group, which may be related to the pathological changes of intestinal metabolic homeostasis and inflammatory markers [ 48 ].…”

“…These data facilitate understanding of the relationship between gut microbial taxa and metabolism, as well as the influence of gut microbes on host health (Sommer and Backhed, 2013). However, as in other avian studies on gut microbiota, one limitation of the current study is the acquirement of DNA from each individual bird, as this affects the study of gut microbiota in relation to host genetics and physiology at the individual level (Liu et al, 2020).…”

The oriental white stork (Ciconia boyciana) is considered an endangered species based on the International Union for Conservation of Nature (IUCN) Red List. This study presents the first evidence on comparative analysis of gut microbial diversity of C. boyciana from various breeding conditions. To determine the species composition and community structure of the gut microbiota, 24 fecal samples from Tianjin Zoo and Tianjin Qilihai Wetland were characterized by sequencing 16S rRNA gene amplicons using the Illumina MiSeq platform. Firmicutes was found to be the predominant phylum. Analysis of community structure revealed significant differences in the species diversity and richness between the populations of the two breeding conditions. The greatest α-diversity was found in wild C. boyciana, while artificial breeding storks from Tianjin Zoo had the least α-diversity. Principal coordinates analysis showed that the microbial communities were different between the two studied groups. In conclusion, this study reveals the species composition and structure of the gut microbiota of oriental white storks under two breeding conditions, and our findings could contribute to the integrative conservation of this endangered bird.

“…3a), and occasionally in other studies [25,27]. Because snakes are carnivorous, their gut microbiomes included phyla present in other carnivores (e.g., coyotes [43], foxes [44], raccoon dogs [45], and tigers [46]), which highlights the extensive effects of diet on the gut microbiome in animals. Among these ve phyla, Bacteroidota, Proteobacteria, and Fusobacteriota showed greater abundance at luminal sites, whereas Firmicutes and Actinobacteriota tended to show greater abundance at mucosal sites (Table 1).…”

Background The gut microbiomes of animals have been widely investigated, but the effects of sampling sites in the gastrointestinal tract remain unclear. Previous studies regarding the gastrointestinal biogeography of microbiomes generally focused on longitudinal comparisons, whereas few studies have compared luminal and mucosal microbiomes. Investigations of the snake gut microbiome have attracted interest because of the unique digestive physiology and hibernation behavior, but adequate sampling methods must be developed. Here, we used an omics approach combining 16S rRNA gene sequencing with untargeted metabolomics to profile the luminal and mucosal gut microbiomes and metabolomes in oriental rat snakes, with the goal of revealing the heterogeneity and co-occurrence at these sites. Results The α-diversity of the gut microbiome was significantly higher at mucosal sites than at luminal sites. Microbial composition also differed according to sampling site, with significant differences in the abundances of dominant phyla and genera, as well as β-diversity clustering and distribution. Metabolome profiling revealed differences that were mainly related to cholinergic substances and nucleic acids. Analysis of variations in Kyoto Encyclopedia of Genes and Genomes functions of microbes and metabolites showed that the mucosal microbiome was more frequently involved in genetic information processing and cellular processes, whereas the luminal microbiome generally participated in metabolic regulation. Notably, we found a greater abundance of the opportunistic pathogen genus Escherichia-Shigella at luminal sites, and higher levels of the lipid-regulator metabolite fenfluramine at mucosal sites. Despite the extensive differences between the two sampling sites, the results revealed similarities in terms of amplicon sequence variant composition and dominant core microbes. Conclusions Our results partly support the hypothesis that the luminal microbiome is associated with metabolism, whereas the mucosal microbiome mainly contributes to immune function. Although studies of the snake microbiome have been limited, this pilot exploration of luminal and mucosal microbiomes and metabolites provides key insights to guide future research.
