Antimicrobial resistance (AMR) is a global health challenge requiring cross-sector action, with research largely focused on chickens, leaving ducks underexplored. This study examines AMR dynamics in Ross 308 broilers and Cherry Valley ducks over 15 months and 15 stocking periods under consistent rearing conditions. A total of 96 pooled samples were collected: 50 from broiler farms (26 biological, 24 environmental) and 46 from duck farms (24 biological, 22 environmental). Using next-generation shotgun sequencing, 3,665 distinct AMR types were identified: 1,918 in broilers and 1,747 in ducks. Host-specific AMRs comprised 25.3% in broilers and 18% in ducks, while 56.7% were shared. AMR diversity declined across production phases, with broilers losing 641 types and ducks losing 308, yet AMR frequencies increased significantly by the finisher phase (p < 0.0001). Based on in silico data, prophylactic antibiotic use significantly reduced the prevalence of multidrug-resistant bacteria in both poultry species (p < 0.05). Hospital-acquired infection-associated AMRs were higher in broilers than in ducks at the start of production but declined significantly by the end of the rearing period (p < 0.0001). Above-average resistance markers accounted for approximately 10% of all detected resistance determinants. Tetracycline and phenicol resistances emerged as the most prevalent. 13 high-resistance carrier (HRC) species were shared between both hosts. Broiler-specific HRCs exhibited significantly higher abundances (relative frequency: 0.08) than duck-specific HRCs (relative frequency: 0.003, p = 0.035). The grower phase emerged as a critical intervention point. In farm environments 15 broiler-specific and 9 duck-specific biomarker species were identified, each strongly correlated with poultry-core HRCs (correlation coefficient > 0.7). Broiler exhibited higher abundances of key resistance genes, with tetracycline resistance predominantly associated with Bacteroides coprosuis, Pasteurella multocida, and Acinetobacter baumannii. Despite its limitations, this research provides key insights into AMR trends in two major poultry types, guiding targeted interventions and sustainable management strategies.

Soil salinity is a major global challenge, reducing fertility and crop productivity. This study evaluated the effects of various soil management practices on the physical, chemical, and microbial properties of saline soils. Six treatments, combining loosening, ploughing, disking, and gypsum amendment, were applied to solonetzic meadow soil with high sodium levels. Soil penetration resistance was measured using a Penetronik penetrometer, while chemical analyses included pH, total salt content, calcium carbonate (CaCO₃), humus, and exchangeable cations (Na⁺, K⁺, Ca²⁺, Mg²⁺). Microbial composition was determined through DNA extraction and nanopore sequencing. The results showed that level A had the lowest penetration resistance (333 ± 200 N/m²), indicating better conditions for plant growth. Gypsum and loosening treatment significantly improved penetration resistance (141 N/m², p < 0.001), while gypsum amendment enhanced chemical properties (p < 0.05, p < 0.01, and p < 0.001). Gypsum application balanced soil parameters and influenced microbial communities. Reduced tillage favored functionally important microbial genera but did not support fungal diversity (p > 0.05). These findings highlight the effectiveness of gypsum amendment and tillage practices, like loosening and disking, in mitigating salinity stress and fostering beneficial microbial communities. Combining gypsum with these tillage methods proved most effective in enhancing soil health, offering insights for sustainable soil management in saline environments.

Bioaerosols have risen as pivotal constituents of airborne particles. Closely intertwined with the agricultural domain, these particles exert a significant influence on crops through the dissemination of various microorganisms that modulate crop growth dynamics, adaptive responses to environmental stimuli, and the nutritional profile of agricultural products. As the main vector, airborne particles are at the forefront in the transmission of plant pathogens. Therefore, this review explains the main factors influencing their composition in agricultural settings and their spreading. Furthermore, it elucidates the complex bioaerosol-based communication networks, including bacteria–bacteria, bacteria–plant, and plant–plant interactions, mediated by specialized volatile organic compounds (VOCs) released by plants and bacterial volatile compounds (BVCs) produced by bacteria. These compounds play a crucial role in synchronizing stress responses and facilitating adaptive processes. They serve as a pathway for influencing and regulating the behavior of both plants and microorganisms. Delving into their origin and dispersion, we assess the key methods for their collection and analysis while also comparing the strengths and weaknesses of various sampling techniques. The discussion also extends to delineating the roles of such particles in the formation of biodiversity. Central to this discourse is an in-depth exploration of their role in the agricultural context, particularly focusing on their potential utility in forecasting pathogen transmission and subsequent plant diseases. This review also highlights the importance of applying bioaerosol-based strategies in the promotion of sustainable agricultural practices, thus contributing to the advancement of ecological balance and food security, which remains a neglected area in scientific research.

Soil health is fundamental for food security, climate regulation, and ecosystem resilience, yet global research and development efforts remain uneven and fragmented. To provide a more integrated perspective, this study examines global soil health research and development trends between 1990 and 2025 while proposing a microbiome-based framework for soil health assessment. Using a PRISMA-based methodology, we combined data from international development projects, scientific publications, patent data, and microbiome-related initiatives to evaluate temporal, thematic, and regional patterns in soil research. The results reveal a sustained increase in global soil-related research, with nutrient management and soil degradation remaining dominant topics, while soil microbiome research and carbon sequestration have emerged as the fastest-growing areas, particularly since 2015. However, significant regional disparities persist, with research concentrated in Asia, Europe, and North America. To address the lack of a coherent microbiome-based soil health assessment system, we propose a structured microbial indicator framework based on twelve functional microbial groups, evaluated through culturable abundance, functional gene abundance, and relative abundance. Additionally, we introduce a unified, database-driven microbiome reference framework that interprets soils relative to known types and conditions. Overall, this study highlights the global transition toward biologically driven and system-oriented soil research and provides a conceptual foundation for more standardized, scalable, and ecologically meaningful soil health assessment.

Background/Objectives: Endothelial dysfunction plays a central role in the development of cardiovascular diseases. β-Casomorphin-7 (BCM-7), a biologically active peptide generated during the digestion of A1 β-casein, is presumed to contribute to this process; however, its direct effects on endothelial cells have not been previously investigated. Here, we aimed to assess whether BCM-7 treatment induces endothelial cell dysfunction through inflammatory cytokines and reactive oxygen species (ROS). Methods: In our study, we analyzed the effects of BCM-7 (5 µg/mL) in combination with lipopolysaccharide (LPS, 100 ng/mL) on human umbilical vein endothelial cells (HUVECs/TERT2). The cell viability, apoptosis, necrosis, and intracellular reactive oxygen species were measured. Furthermore, proinflammatory cytokines and enzymes involved in the regulation of inflammation were assessed with quantitative real-time PCR. The gene and protein expression of enzymes that regulate inflammation and vascular function, thus maintaining endothelial homeostasis were assessed. Results: BCM-7 enhanced intracellular ROS production p ≤ 0.001, increased the expression of interleukin-6 (IL-6) and interleukin-8 (IL-8) p ≤ 0.001, and was more effective when used in combination with LPS p ≤ 0.001. It decreased the expression of cyclooxygenase-1 (COX-1) p ≤ 0.05, during 4 h of exposure, whereas it increased the expression of cyclooxygenase-2 (COX-2) p ≤ 0.001, lipoxygenase-5 (LOX-5) p ≤ 0.01, and nitric oxide synthase 3 (NOS3) p ≤ 0.001; prostaglandin D2 synthase (PTGDS) (p ≤ 0.05), expression was also increased after short treatment. Conclusions: Our results suggest that BCM-7 may contribute to the development of endothelial dysfunction, especially in the presence of LPS, by enhancing oxidative stress and inflammatory response.

Background: Our previous studies demonstrated that sour cherry anthocyanins (AC) reduce the salivary count of Streptococcus mutans and inhibit salivary amylase activity within 30 minutes after chewing AC gum. AC gum and changing toothbrushes after scaling reduced the Gram-negative species in the unstimulated salivary microbiota. The present study examined the effect of AC gums on salivary factors, including changes in microbiome. Methods: The study was conducted over three weeks with two groups; young adults (18–30) and adults (30–45). Ten participants changed their toothbrushes, while the other 10 participants did not change after the control period. After scaling, all participants received three doses of AC gum daily. The salivary mRNA and protein levels of cytokines, mucins, melatonin, and the microbiota of unstimulated and stimulated saliva were determined by polymerase chain reaction, enzyme-linked immunosorbent assay, and 16S rRNA gene sequencing. Results: Significantly higher levels of tumor necrosis factor α (TNFα), interleukin-1β (IL-1β), mucin5B (MUC5B), mucin7 (MUC7), and melatonin were detected in stimulated saliva. Correlation analysis of these factors with the microbiota showed positive correlations with the genera Lachnospiraceae, Eikenella, Saccharibacteria_(TM7), Streptococcus, Prevotella, and Haemophilus. Conclusions: AC chewing gum has a beneficial effect on the composition of the oral microbiome, and toothbrush replacement leads to changes in the levels of salivary pro-inflammatory cytokines.
