Succession of embryonic and the intestinal bacterial communities of Atlantic salmon (Salmo salar) reveals stage-specific microbial signatures.

ABSTRACT: Host-associated microbiota undergoes a continuous transition, from the birth to adulthood of the host. These developmental stage-related transitions could lead to specific microbial signatures that could impact the host biological processes. In this study, the succession of early-life and intestinal bacterial communities of Atlantic salmon (starting from embryonic stages to 80-week post hatch; wph) was studied using amplicon sequencing of 16S rRNA. Stage-specific bacterial community compositions and the progressive transitions of the communities were evident in both the early life and the intestine. The embryonic communities showed lower richness and diversity (Shannon and PD whole tree) compared to the hatchlings. A marked transition of the intestinal communities also occurred during the
