Summary: This study found that paroxetine has a biphasic effect on the gut, affecting both steroidogenesis and the gut microbiota. The steroid modifications observed immediately after treatment are different from those detected at withdrawal.

Summary: Aquaculture is a rapidly growing industry, but the use of fishmeal as a feed ingredient is not sustainable in the long-term. Insect meals and probiotics have emerged as potential alternatives to fishmeal and have shown positive effects on fish growth and health.

Summary: This study investigated the bacterial composition and metabolic functions in the phytotelmata of Pseudalcantarea grandis in vegetated and non-vegetated sites in an arid zone. The results showed differences in bacterial diversity between the two sites, with shared dominant metabolic functions. Rare bacterial phyla and families were also identified, which may contribute to the resilience and resistance of the micro-ecosystem.

Summary: This paper emphasizes the correct assignation of indicator phospholipid fatty acids (PLFA), the specificity and recycling of PLFA in microorganisms, and the complete extraction and detection of PLFA. It suggests using different PLFA indicators for different microbial groups and optimizing soil handling and PLFA analysis methods. The study also points out the importance of regular checks on gas chromatographic separation for reliability and accuracy.

Summary: The objective of this study was to determine if selected fish genotypes could benefit from the use of functional additives in novel aqua feed formulations to improve growth performance, gut microbiota, immune response, and disease resistance in fish. The results showed that fish from the high growth genotype performed better in terms of body weight, relative growth, SGR, and DGI. The diet had a significant effect on fish survival and there was an interaction between genotype and diet in relation to gene expression in the distal gut. The study also revealed the impact of additives on the relative abundance of certain taxa in the fish gut microbiota.

Summary: This study found that the adiposity of women before pregnancy and during lactation is associated with the abundance of Bacteroidetes and Actinobacteria in human milk. This finding reveals a relationship between the microbiota of human milk and the mother's obesity status.

Summary: Soil warming has complex effects on microbial communities, reducing microbial diversity while increasing the role of dominant microbiomes in regulating nutrient and energy flow. Wetland ecosystems are more sensitive to temperature increases, and changes in microbial communities align with overall trends.

Summary: This study examined the microbial community of arable soils cultivated with barley under different applications of biosolids, simulating a 10-day flood. The results showed that biosolid application did not significantly change the soil microbiome, and the bacterial populations returned to their pre-flood profiles after flooding. This suggests that biosolid application does not increase environmental risk during flooding.

Summary: The study aimed to investigate the development and composition of the gut microbiota in commercially raised layer flocks from hatch to end of the production cycle. The results showed differences in microbiota composition across different flocks and changes in richness, diversity, and composition as the birds matured. A deeper understanding of normal microbiota development in layers may provide opportunities for improving gut health and productivity through microbiota management.

Summary: Conventional sewage treatment plants generate by-products, such as sludge, that require proper treatment and dewatering. Reusing the sludge as fertilizer in agriculture is a promising alternative, but the feasibility depends on sludge treatment technologies that can effectively dewater and treat pollutants. Biological treatments, particularly bioleaching, have gained popularity due to their economic and environmental benefits. This study investigates the microbiological aspects of dewatering during the bioleaching process and provides valuable information for future research on the application of bioleaching in sewage sludge treatment.

Summary: The bacterial composition of naturally fermented Indian food, Idli, was analyzed using high-throughput Illumina amplicon sequencing. The study found that Firmicutes and Proteobacteria were the predominant bacterial phyla in Idli, with their proportions changing during fermentation. Additionally, co-occurrence and co-exclusion networks were established to analyze the positive and negative associations among bacterial genera.

Summary: This study evaluated bacterial diversity and community structure in glacial soil and meltwater runoff at the frontier of Baishui Glacier No.1 using high throughput sequencing. The results showed that bacterial diversity was higher in soil compared to water, with soil samples having a more similar taxonomic composition influenced by ecological parameters. The relative abundance of bacterial phyla varied greatly between soil and water samples, with Proteobacteria dominating in water runoff and Acidobacteria, Actinobacteria, and Bacteroidetes dominating in soil. Environmental factors played a significant role in determining bacterial community structures in this ecosystem.

Summary: The study investigated the effects of Eimeria tenella infection on the cecal microbiome, protein concentration, cecal mucosal immunity, and serum endotoxin levels in broilers. The results showed that Eimeria tenella infection altered the composition of the cecal microbiome, suppressed cecal mucosal immunity, and increased protein concentration in the cecal content.
