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

Characterization of the gut and skin microbiomes of wild-caught fishes from Lake Guntersville, Alabama
TL;DR: Characterization of the gut and skin microbiomes of three common freshwater fishes including two important sport fishes, largemouth bass Micropterus salmoides and bluegill Lepomis macrochirus as well as the distantly-related spotted gar to identify potential influences of seasonality on core microbial communities.

[Study of the Microbiome of the Intestine of the Comephorus dybowski Korotneff, 1904].
TL;DR: Data on metagenomic analysis of the microbial community of the intestine of the Comephorus dybowski are presented and it was established that the bacterial community is characterized by a significant species diversity.
The microbiota-gut-brain axis. a study in zebrafish (danio rerio)
TL;DR: The results of each approach may support the existence of a microbiota–gut–brain axis, in adult zebrafish and in line with numerous animal studies the authors can speculate that microbiota manipulation could influence behavior and brain expression of BDNF.
