Summary: Honey bees play a crucial role in food production and biodiversity maintenance through pollination. They have different survival strategies in cold temperate regions and experience lifecycle alterations in tropical or subtropical climates. The gut microbiota of honey bees in subtropical colonies changes seasonally, with environmental variables impacting its composition.

Summary: The fish external microbiota competitively excludes pathogens and prevents proliferation of opportunistic organisms. Prolonged exposure to dispersed oil leads to dysbiosis in fish external microbiota, reducing the host's immune response to pathogens.

Summary: The study found a high prevalence of AIEC in CD patients in Hong Kong, which was associated with severe microbiota dysbiosis and impeded restoration of normal gut microbiota. AIEC may serve as a keystone bacterium in CD and impact the efficacy of FMT.

Summary: This study demonstrates that gut microbiota disturbance caused by metabolic abnormalities of gut microbiota is associated with the occurrence and development of mastitis. The underlying mechanism of how gut dysbiosis leads to mastitis pathogenesis remains unclear. Additionally, the regulation of commensal bacteria and gut metabolism may provide a potential strategy for mastitis intervention.

Summary: The bioavailability of anthocyanins in red radish (ARR) is low. This study found that co-ingestion of fructo-oligosaccharide (FOS) with ARR increased the levels of pelargonidin, cyanidin, and pelargonidin-3-glucoside in mouse serum and enhanced hepatic antioxidant activity. The 16S RNA sequencing identified Bacteroides genus as playing a crucial role in FOS-mediated elevation of ARR bioavailability. These findings suggest that combining FOS and ARR could be an effective strategy to enhance the bioactivity of ARR.

Summary: This study identified the mucin-microbiome signatures in gastric adenocarcinomas and their impact on clinical outcomes. The findings showed that intestinal mucin phenotype and high-level MUC13 expression were associated with poor survival, while gastric MUC5AC or MUC6 abundance was associated with a more favorable outcome. Furthermore, oral bacteria such as Neisseria, Prevotella, and Veillonella were found to play a potential role in MUC13 signaling and were associated with intestinal and mixed mucin phenotype tumors.

Summary: Red Snapper were collected from the Gulf of Mexico from 2011 to 2017 and analyzed for biliary FACs, hepatic PAHs, and microscopic hepatobiliary changes. The study found a potential link between increased PAH exposures and disease progression in Red Snapper. While biliary FACs levels varied annually, hepatic PAH concentrations remained relatively stable in the studied fish, with most individuals showing microscopic hepatic changes.

Summary: Red clover supplementation can significantly improve muscle performance in female mice and have a positive impact on gut microbiota. The findings suggest that red clover can enhance physical performance, reduce fat mass, and help control the accumulation of lactate and ammonia in the body.

Summary: The gut microbiomes of human populations worldwide have common core microbial species. However, within a species, certain strains show population specificity. This study suggests that humans and their gut microbes have experienced parallel evolutionary history, and specific microbial strains may play a crucial role in microbiome-mediated disease phenotypes.

Summary: This study compares the composition of microbiota in the intestines of wild and aquaculture red cusk-eel and finds significant differences between the two. The microbiota in aquaculture conditions is dominated by Firmicutes, while in the wild conditions it is dominated by Tenericutes. Differences in predicted metabolic pathways were also observed, with a focus on lipid metabolism in the wild conditions.

Summary: With a 14-day intervention trial, this pilot study investigated the changes in gut microbial populations following red beetroot consumption. The study found transient changes in the abundance of certain bacteria taxa after different days of intervention (p < 0.05). Akkermansia muciniphila was enriched and Bacteroides fragilis decreased after 3 days of juice consumption, followed by restoration in abundance after 14 days (p < 0.05). The presence of native betacyanins and catabolites in stool after juice consumption was also observed, with betacyanins positively correlated with Bifidobacterium and Coprococcus, and inversely correlated with Ruminococcus (p < 0.1), leading to a significant rise in (iso)butyric acid content (172.7 +/- 30.9 mu mol/g stool). These findings suggest the potential benefits of red beetroot on gut microbial populations and associated catabolites, highlighting its impact on intestinal and systemic health.
