Summary: In this study, potential biomarkers and microbial species associated with finishing weight in Diannan small ear pigs were identified. Carbohydrate-decomposing bacteria were positively related to finishing weight, while microbial taxa associated with intestinal inflammation and damage had opposite effects. Gut microbial functional annotation analysis revealed that certain enzymes and SCFA levels, especially acetate and butyrate, played crucial roles in regulating finishing weight.

Summary: The importance of the gut-liver axis in the pathophysiology of metabolic dysfunction-associated fatty liver disease (MAFLD) is being investigated more closely in recent times. This study assesses the time-dependent gut dysbiosis in MAFLD, its implications in disease progression, and the role of plant-derived prebiotics in its attenuation.

Summary: The gut microbiota serves as a reservoir for antibiotic resistance genes (ARGs), which can potentially impact the health of humans and animals. The impact of diet on the intestinal flora and antibiotic resistome in rabbits remains unclear. Feeding rabbits lettuce grown with different manure types leads to the amplification and transfer of exogenous ARGs in the intestinal flora, posing a potential threat to health.

Summary: To understand the biases in human gut microbiome studies, a reference microbiome composed of an artificial mock community is crucial. However, there is a lack of suitable mock communities that accurately represent the human gut microbiome. In this study, we created a novel mock community consisting of 18 major bacterial species found in the human gut and examined the impact of experimental and bioinformatics procedures on 16S rRNA gene and shotgun metagenomic sequencing. Our findings revealed that DNA extraction methods significantly influenced DNA yields and taxonomic composition of sequenced reads and certain commonly used primers for 16S rRNA genes led to underestimation of certain gut commensal taxa. Additionally, we demonstrated that the binning of shotgun metagenomic sequences using MetaBAT2 produced consistent, less-contaminated bins with varying completeness. The use of multiple binning tools with MetaWRAP improved completeness but sometimes increased contamination rate. This benchmark study provides a crucial foundation for interpreting human gut microbiome data, allowing for standardization among different methodologies, and facilitating the advancement of analytical methods.

Summary: This study investigated the impact of different β-glucans on the gut microbiome in rats and found that oat β-glucan and curdlan increased the abundance of specific bacterial genera, while a positive correlation was observed between Streptococcus bacteria and the growth rate of rats. Consuming β-glucans at the recommended dose by EFSA did not significantly alter the structure of the gut microbiome in rats.

Summary: This study investigates the differences in gut microbiota composition between patients with type A aortic dissection (AAD) and healthy controls. The microbiome composition can accurately predict AAD and is associated with inflammation. These findings will contribute to the development of preventive and therapeutic strategies for AAD.

Summary: For commercial swine producers, the natural variation in body weight amongst pigs in a herd presents a challenge in meeting the standards of meat processors who incentivize target carcass weights by offering more favorable purchase prices. The gut microbiome has emerged as an important factor that can affect growth performance and efficiency in swine, as it contributes to vital functions such as providing assimilable nutrients and resistance to infection. This study compared the fecal microbiomes of light and heavy barrows and identified two bacterial species in higher abundance in the light barrows group, which may play roles in promoting beneficial microorganisms and utilizing starch in the swine gut.

Summary: Bullous pemphigoid patients have altered gut microbiota composition and function, with decreased microbial diversity and overall changed microbial community. Disease-associated gut microbial features, including reduced Faecalibacterium prausnitzii and increased pathways related to gamma-aminobutyric acid metabolism, are observed in BP patients. These findings suggest that gut microbiota alterations may play a role in the development of bullous pemphigoid.

Summary: This study explored the relationship between weight gain in schizophrenia patients with atypical antipsychotic treatment and gut microbiome. The results showed that there were no significant differences in alpha diversity between normal-weight and overweight schizophrenia patients treated with atypical antipsychotics. However, the beta diversity analysis revealed distinct clustering patterns for overweight and normal-weight patients. The composition of the gut microbiome also differed between the two groups. Function prediction identified several pathways that were significantly different between groups. Correlation analysis indicated associations between specific bacteria and BMI. Overall, these findings suggest that perturbations in the gut microbiome composition and functional pathways may contribute to weight gain in schizophrenia patients treated with atypical antipsychotics.

Summary: The study characterized the gut microbiome in Usherhopper, Poekilocerus bufonius, revealing Proteobacteria as the most common phylum and Wolbachia as the dominant genus. The intricate interactions between the microbiome and the host play a significant role in the ecosystem, warranting further research.

Summary: Research has shown that exposure to tobacco carcinogens leads to significant changes in the gut and lung microbiomes, which are associated with the development of lung adenocarcinoma (LUAD) and immunotherapeutic response in human lung cancer patients. Loss of the bacterial growth inhibitor Lcn2 also results in widespread changes in the gut and lung microbiomes. These findings shed light on the role of microbial phenotypes in the development of tobacco-associated LUAD.

Summary: This study investigated the effects and mechanisms of mulberry and paper mulberry silages on growth performance, meat quality, and intestinal health of finishing pigs. The results showed that mulberry silage improved meat quality and increased the concentration of short-chain fatty acids (SCFAs). The microbial composition in the intestine was also affected by mulberry silage. These findings have important implications for improving pork quality.

Summary: The study revealed that MystA and MystB in Aspergillus flavus play significant roles in regulating conidiation, sclerotia formation, and aflatoxin production, with MystB being particularly important. Additionally, the catalytic domain and catalytic site of Myst are crucial for its acetyltransferase function, and mystB is involved in oxidative detoxification.
