Summary: Dietary nutrients and the gut microbiota have a reciprocal relationship that affects the host's health and immune-mediated diseases. This review explores how this interaction influences the host's immunity and highlights the potential of gut microbiota-targeted dietary interventions in immune-associated diseases.

Summary: The study evaluated the influence of two different lipid sources (fish oil and vegetable oil) in the diet on the intestinal microbiota of early life stages of Atlantic salmon, finding that the fish growth did not significantly differ between the two diets. Additionally, it was observed that the gut microbiota composition changed with age.

Summary: This study aimed to determine whether gut microbiota composition could be a useful indicator of a long-term dietary pattern. The results suggest that gut microbiota composition at the genus level is not a reliable predictor of an individual's dietary pattern, except for vegans who have a high abundance of Prevotella 9. A combination of multiple variables, including anthropometric measurements, serum biomarkers, lifestyle factors, gastrointestinal symptoms, psychological factors, and specific nutrient intake, is more important in predicting an individual's microbiota composition cluster with 91% accuracy than dietary intake alone.

Summary: The composition and activity of gut microbiota are significantly influenced by dietary intake of carbohydrates and proteins. High fiber intake and protein quality and digestibility can modulate microbial metabolism and composition. Understanding the impact of dietary patterns on host-microbiome interaction is essential for developing targeted interventions.

Summary: Dietary carbohydrate levels can affect gut health and the interactions between gut microbiota and gut epithelial cells. Low-carbohydrate diet leads to dysregulated gut microbiota and compromised metabolic function. High-carbohydrate diet can cause severe gut damage by affecting immune function of microbiota and antioxidant capacity. Major histocompatibility complex class I antigen (MR1) might be a central target for immune responses in gut epithelial cells induced by gut microbiota at different carbohydrate levels.

Summary: This study investigated the effects of bile acids on gut barriers in Micropterus salmoides. The results showed that feeding diets supplemented with bile acids can improve gut structure and survival rate of fish. The effects of bile acids on gut barriers are mediated by both direct stimulation and indirect regulation through gut microbiota.

Summary: Polyphenols, important secondary metabolites produced by plants, have multiple health benefits. Most dietary polyphenols are not absorbed in the gastrointestinal tract, but are transformed into bioactive metabolites by gut microbiota in the large intestine. Dietary polyphenols can modulate the composition of gut microbes, which in turn catabolize polyphenols to release bioactive metabolites.

Summary: The study demonstrates that adding purslane to feed can significantly improve the growth performance of Sanhuang broilers and positively influence their gut microbiota. The inclusion of purslane increases the abundance of Lactobacillus in the gut, promotes carbohydrate metabolism, and enhances the growth performance of Sanhuang broilers.

Summary: The gut microbiota plays a crucial role in host health, and changes in the microbiota have been associated with various diseases. Recent studies have shown that secretory immunoglobulin A (SIgA) in the intestinal mucosa is essential in controlling the microbiota. Dietary interventions have been found to influence the SIgA response and the interaction between SIgA and the microbiota, either directly or indirectly. However, there is still limited research on the specific influence of dietary interventions on the SIgA-GM interaction.

Summary: Our gut microbiota have co-evolved with us over a long period of time, playing a crucial role in our overall health and influencing various bodily processes. The microbiota-gut-brain axis is a dominant communication pathway with far-reaching implications for our well-being. Dietary composition, particularly in modern Western diets, can directly impact the abundance and diversity of gut microbiota, leading to dysbiosis and potential health issues.

Summary: The presence of gut microbiota, especially arsenic-resistant bacteria such as Stenotrophomonas maltophilia, plays an important role in the accumulation and transformation of arsenic in fish. Removing the gut microbiota through antibiotic treatment significantly reduces the levels of total arsenic and arsenobetaine in the intestines and muscles of fish. Arsenic exposure alters the composition of the fish gut microbiota, with S. maltophilia becoming the dominant species. In vitro experiments demonstrated that the gut contents of untreated fish can metabolize arsenate to arsenite and organoarsenicals, while antibiotic-treated fish lose this ability.

Summary: A healthy gastrointestinal microbiota is vital for host fitness and is strongly affected by host diet. Feeding carnivorous fish plant-based diets high in non-starch polysaccharides (NSP) can lead to changes in gut microbiota composition, favoring bacterial families with carbohydrate active enzymes. Overall, the gut communities of European seabass respond to plant-based diets by adjusting to the presence of transient microorganisms with carbohydrolytic potential while maintaining a balanced core microbiota.

Summary: The study found that enriching farmed tilapia with a high omega-3 (n-3) Thraustochytrids protist oil source before harvesting can significantly increase the n-3 content of the fillet. Docosahexaenoic acid (DHA) is the main attributing fatty acid for the n-3 increase and can improve the lipid composition of tilapia. This technique could provide consumers with more nutritional benefits beyond high-quality protein.

Summary: This study evaluated three different routes of Streptococcus agalactiae infection in Nile tilapia and found that intraperitoneal and intragastric routes were more aggressive, causing greater brain damage and early mortality, while oral inoculum presented less intensity in brain lesions and a chronic immune response, with longer mortality time. Oral infected-feed administration may be an innovative method for future aquaculture research experiments.

Summary: The current study investigated the effects of dietary mannan-oligosaccharides (MOS) on growth, hemato-biochemical changes, digestive-antioxidant enzyme activity, immune response, and disease resistance in milkfish. The results showed that milkfish fed MOS diets had significant impacts on growth parameters, feed conversion ratio (FCR), and protein efficiency ratio (PER). The inclusion of 2g or 3g MOS in the diet resulted in higher levels of total protein (TP), globulin (GB), glucose (GLU) levels, as well as increased enzyme activity. The addition of MOS also increased gut microflora and enhanced antioxidative enzyme activity.

Summary: A three-month feeding trial was conducted to determine the protein requirement of bullseye snakehead. The results showed that diets with 55% crude protein had the highest growth performance and nutrient profile. However, the study also highlighted the presence of an upper protein constraint and suggested further quantitative studies.
