Fish intestinal microbiome: diversity and symbiosis unravelled by metagenomics.
TLDR
This review aims to summarize the available knowledge on fish gastrointestinal communities obtained from metagenomics, including biases from sample processing, factors influencing assemblage structure, intestinal microbiology of important aquaculture species and description of the teleostean core microbiome.Abstract:
The gut microbiome of vertebrates plays an integral role in host health by stimulating development of the immune system, aiding in nutrient acquisition and outcompeting opportunistic pathogens. Development of next-generation sequencing technologies allows researchers to survey complex communities of microorganisms within the microbiome at great depth with minimal costs, resulting in a surge of studies investigating bacterial diversity of fishes. Many of these studies have focused on the microbial structure of economically significant aquaculture species with the goal of manipulating the microbes to increase feed efficiency and decrease disease susceptibility. The unravelling of intricate host-microbe symbioses and identification of core microbiome functions is essential to our ability to use the benefits of a healthy microbiome to our advantage in fish culture, as well as gain deeper understanding of bacterial roles in vertebrate health. This review aims to summarize the available knowledge on fish gastrointestinal communities obtained from metagenomics, including biases from sample processing, factors influencing assemblage structure, intestinal microbiology of important aquaculture species and description of the teleostean core microbiome.read more

Freshwater transfer affected intestinal microbiota with correlation to cytokine gene expression in Asian sea bass
TL;DR: In this paper , the effects of transfer to hypotonic environments on a catadromous fish microbiota was investigated and the relationship between the water and the gut microbiota of this euryhaline species was also examined.

Phylogenetic identification and in situ detection of individual microbial cells without cultivation.
TL;DR: Phylogenetic analysis of the retrieved rRNA sequence of an uncultured microorganism reveals its closest culturable relatives and may, together with information on the physicochemical conditions of its natural habitat, facilitate more directed cultivation attempts.

TL;DR: This article proposes rational taxonomic boundaries for high taxa of bacteria and archaea on the basis of 16S rRNA gene sequence identities and suggests a rationale for the circumscription of uncultured taxa that is compatible with the taxonomy of cultured bacteria and Archaea.

The core gut microbiome, energy balance and obesity
TL;DR: It is indicated that a core microbiome can be found at the gene level, despite large variation in community membership, and that variations from the core are associated with obesity.
