“…Notably, the relative abundance of Proteobacteria was higher in entire male pigs, and the relative abundance of Actinobacteria was higher in castrated male pigs. Previous studies showed that Proteobacteria is the dominant phylum in the gut microbiome of pandas and plays a key role in the digestion of lignin food sources [35,36]. A further study also pointed out that the abundance of Proteobacteria is very important for intestinal health [37].…”

The gut microbiome plays an important role in the health and disease status of the host. Research on the effect of sex on animal intestinal microorganisms is still limited; and the effect of castration on the gut microbiome of male pigs has not been fully investigated. In this study, 30 Hainan special wild boars at the same growth stage were divided into three groups (10 entire males, 10 females, and 10 castrated males). High-throughput 16S rRNA sequencing was used to investigate the fecal microbiota of the Hainan special wild boar. Firmicutes, Bacteroidetes, Actinobacteria, Spirochaetes, and Proteobacteria were the five dominant phyla found in the specimens. The relative abundance of Bacteroidetes was higher in the microbiota of female pigs than in male pigs, while Firmicutes was on the contrary. The percentage of Streptococcus and Lactobacillus was higher in males than females. The microbial diversity of females was significantly higher compared to males; castration increased the intestinal microbial diversity of males. Functional prediction showed that male fecal microorganisms were rich in membrane transport and carbohydrate metabolism; energy metabolism, glycan biosynthesis, and metabolism of cofactors and vitamins were rich in the female group; the fecal microorganisms of castrated males had higher membrane transport abundance.

“…The Proteobacteria was identified as dominant species in giant pandas and red pandas, which played a key role in digestion of the main food sources of lignin. Proteobacteria are often found in the natural environment and individual wild animals may do accumulate more [31, 34, 35]. An increased prevalence of the bacterial phylum Proteobacteria is a marker for an unstable microbial community (dysbiosis) and a potential diagnostic criterion for disease.…”

Animal gut microbiota begins to colonize after birth and is functionally indispensable for maintaining the health of the host. It has been reported that gender and age influence the composition of the intestinal microbiome. However, the effects of gender and age on the intestinal microorganism of forest musk deer (FMD) remain unclear. The aim of this study was to establish the relationship between the structure and composition of fecal microbiota of male and female forest musk deer with age. Here, Illumina Miseq 300PE sequencing platform targeting 16S rRNA V3–V4 hypervariable region applied to define the fecal microbiota of male and female FMD with two age groups, juvenile (age 1–2 years) and adult (age 4–10 years). Alpha diversity index did not show significant difference in bacterial diversity between the males and females or among age groups. The intestinal microbiota of FMD was dominated by three phyla, the Firmicutes, Proteobacteria and Bacteroidetes regardless of gender and different ages. Higher proportions of Proteobacteria were found in adult male and juvenile female individuals. The composition of Bacteroidetes was stable with the gender and age of FMD. Interestingly, the relative abundance of genera Clostridiales and Bacteroidales were higher in the juvenile FMD. Conversely, proportions of Pseudomonas and Lachnospiraceae were abundant in the adult FMD. Higher proportions of Ruminococcaceae, Dore, and 5-7N15 were found in the juvenile male groups. They may reflect the different immune resistance of male and female individuals at different stages of development. This study explored the fecal microbiota composition of forest musk deer in relation to gender and age, which may provide an effective strategy for developing intestinal microecological preparations and potential musk deer breeding.

“…At the genus level, the relative abundance of Escherichiashigella was significantly different (Supplementary Figure 3) in the different ecological types, with a relatively higher abundance in waterfowl. This genus is also present in the gastrointestinal tract of herbivorous carnivores animals, such as red panda (Zeng et al, 2018). Lactobacillus is one of the groups with abundant differences, and the relative abundance in arboreal birds is relatively high.…”

Differences in intestinal microflora of birds among different ecological types

et al. 2022

The intestinal microflora of animals plays a key role in metabolism, immunity, and development. Birds distributed across multiple ecological habitats. However, little is known about the differences in the intestinal microflora of birds among different ecological types. In this study, bird feces from different ecological types and orders were collected in Chongqing Zoo, China. In this study, high throughput sequencing of the 16S ribosomal RNA (rRNA) gene (amplicon sequencing) and metagenomics were used to analyze the composition and function differences of gut microbiota communities among different ecological types/orders. Firmicutes and Proteobacteria were the dominant bacteria phyla for all samples but there were significant differences in the α-diversity, community structure and microbial interactions between birds of different ecological types. The function differences involve most aspects of the body functions, especially for environmental information processing, organismal systems, human diseases, genetic information processing, and metabolism. These results suggest that diet and habitat are potential drivers of avian gut microbial aggregation. This preliminary study is of great significance for further research on the intestinal microflora of different ecological types of birds.
