This study used metagenome sequencing to analyze the gut microbiota of A. japonicus and found that Bacteroidetes and Proteobacteria were the dominant phyla. The bacterial community in the gut showed asymmetry compared to the surrounding environment, and the gut-colonized bacteria were influenced by the surrounding water and feed, potentially affecting the growth and metabolism of A. japonicus.
Animals are not only regulated by their own genes but also influenced by symbiotic bacteria, most of which are colonized in the gut. The gut bacterial community is involved in plenty of physiological processes; therefore, intestinal colonization by commensal microbiota is essential to the health of the host animal. Here, metagenome sequencing of the A. japonicus gut, surrounding water, and feed was performed to explore the structural and functional characteristics of the colonized bacteria in the gut of A. japonicus. Results showed that Bacteroidetes and Proteobacteria were the main dominant phyla of the A. japonicus gut, and Formosa, Vibrio, and Lactobacillus were the dominant genera. There was asymmetry between the A. japonicus gut and its surrounding environment in the bacterial community. In terms of the top 50 abundant genera, those colonized in the gut shared a similarity of 26% with those colonized in the surrounding water and a similarity of 30% with those colonized in the feed. According to KEGG annotation, the dominant metabolic pathways in the gut of A. japonicus were glycan biosynthesis and metabolism, nitrogen metabolism, and cysteine and methionine metabolism. This implies that the gut-colonized bacteria of A. japonicus are influenced by the surrounding water and the feed. In addition, the gut-colonized bacteria might be related to the growth and metabolism of A. japonicus.
