| Summary: | Research on microbiota has underscored the crucial influence of microbial communities on numerous biological functions that yield positive outcomes for the host, such as digestion, nutrient metabolism, resistance against pathogen invasion, and growth performance. Concurrently, numerous variables, including the host’s diet, genetics, and physiological condition and environmental factors, influence the gut microbiota. Our study aims to characterize the bacterial community composition of the common snake eel (<i>Ophichthus remiger</i>), captured wild and then reared under controlled conditions. We employed a 16S rRNA gene-based approach facilitated by next-generation sequencing to conduct this analysis. The gut microbiota of the snake eel was highly dominated by bacteria from the phylum Firmicutes, comprising over 80% of the relative abundance, with <i>Lactilactobacillus</i> being the most important genus. The results suggest that feed-associated bacteria may influence the composition of the microbiota, contributing the most relevant bacteria within the intestinal content. This study provides the first comprehensive analysis of the gut microbiota in <i>Ophichthus remiger</i>, offering novel insights into the potential roles of <i>Firmicutes</i> and <i>Lactilactobacillus</i> in marine eels. |
