Summary: In this study, the effects of a blend of essential oils on the productive performance and intestinal microbiota of juvenile Nile tilapia were investigated. The results showed that supplementation with 3.3 g kg(-1) of essential oils improved the growth performance and modulated the gut microbiota of tilapia. The maximum levels of the essential oils blend for final weight, weight gain, daily weight gain, and feed conversion were calculated.

Summary: This study investigated the gut microbiota of healthy adults with different traits. The results showed differences in gut microbiota composition between male and female subjects. Additionally, the gut microbiota composition was able to distinguish between different BMI groups. At the phylum level, specific phyla were found to be increased in different BMI groups for both males and females. At the genus level, several distinct genera were identified across BMI groups. The accuracy of predicting body type using a linear regression model was 74%.

Summary: In this study, the gut microbiota of Nile tilapia was analyzed before and after feeding with different concentrations of Chlorella vulgaris. The results showed that only long-term feeding of 2% C. vulgaris significantly increased the diversity of the gut microbiota. Additionally, the composition of the gut microbiota was altered by the addition of 2% C. vulgaris. This study provides valuable insights into the impact of C. vulgaris on the gut microbiota in fish.

Summary: This study analyzed the bacterial composition in the gut of Nile tilapia fish in Egypt and found significant differences in gut bacteria between fish from different lakes. Some of the identified bacteria were pathogenic. The study also showed that the environmental conditions in different lakes can influence the composition of the fish's microbiota, with Nile tilapia in certain lakes being exposed to anthropogenic pollutants.

Summary: The plant microbiome plays a crucial role in plant biology, ecology, and evolution. The study reveals that plant genotype has varying impacts on the diversity, structure, and composition of bacterial microbiomes in fruits, leaves, and soil, with a stronger effect observed in fruits. This suggests that plant genotype is an important factor in shaping the structure of plant microbiomes, providing potential insights for enhancing plant productivity, nutrition, and defenses.

Summary: This study applied metabarcoding to assess the differences among samples of T. magnatum collected from different areas in Tuscany, Italy. The results showed differences in microbial composition between different parts of the truffle (gleba and peridium) as well as between productive and unproductive soils, with distinctive associated taxa. Furthermore, the findings indicated specific characteristics associated with truffle collection areas, suggesting microbial selection related to different environments.

Summary: Understanding the factors influencing microbiome diversity is crucial for understanding host-symbiont interactions and co-evolutionary dynamics. This study focused on wood-warblers and found that host evolutionary history has the strongest influence on gut microbiome differentiation, compared to environmental factors and diet diversity. The similarity of gut microbiomes was more congruent with the host phylogeny than with host diet similarity, suggesting that host traits may play a role in colonization and maintenance of microbes.

Summary: The emergence of resistance against common antibiotics in the gut microbiota is a major issue. Phytogenic feed additives (PFAs) have the potential to improve animal health by positively affecting the gut microbial ecosystem. This study found that PFAs can decrease the abundance of antibiotic resistance genes and could be an alternative to antibiotics in poultry farming.

Summary: This study evaluated the effects of gamma irradiation and heat inactivation on different strains of lactic acid bacteria (LAB) and their ability to preserve metabolic activity and immune modulation. The results showed that gamma irradiation could retain metabolic activity and immune modulation, while heat inactivation could not. Different strains of LAB and inactivation methods had varying impacts on immune modulation, highlighting the potential of gamma irradiation in producing safe non-replicative metabolically active LAB and its application as a vaccine adjuvant.

Summary: This study aimed to simulate the impact of an African swine fever outbreak in Austria and evaluated control strategies and identified bottlenecks. A hybrid approach of discrete-event and agent-based simulation was used. The results compared two control strategies and showed that with a preventive culling strategy, fewer farms would be infected and fewer pigs would be culled.

Summary: Postharvest disease management is crucial for improving crop quality and productivity. The use of agrochemicals in disease control, however, has negative effects on consumer health, the environment, and fruit quality. Microbial biocontrol agents offer an eco-friendly alternative, but their implementation in sustainable agriculture requires further research and understanding of plant-pathogen-environment interactions. This review summarizes previous studies on the function of microbial biocontrol agents against postharvest crop diseases and explores their mechanisms, potential applications, and challenges in commercialization.
