Special Issue Information

Dear Colleagues,

The microbiome and microbiome-derived bioactive substances play essential roles in maintaining health and shaping disease processes in both humans and animals, and growing evidence demonstrates their involvement in key biological and clinical areas, including antimicrobial resistance, metabolic regulation, immune modulation, and host responses to therapeutic and preventive interventions. Rapid advances in sequencing technologies, bioinformatics, and multi-omics approaches have greatly enhanced our ability to characterize microbial communities, resistomes, and host–microbe interactions, while supporting translational applications across human and veterinary medicine.

With this context in mind, this Special Issue aims to provide a multidisciplinary platform for original research articles, high-quality reviews, and short communications addressing both fundamental mechanisms and applied perspectives. Topics of interest include, but are not limited to, zoonosis, microbiome from humans, companion or livestock animals, resistant genes, antibiotic resistance gene (ARG) dissemination, microbiome-associated metabolism, bioactive compounds, database construction and data integration, methodological innovations, and microbiome-informed strategies for disease prevention and vaccine design. Contributions from experimental, clinical, veterinary, and computational studies that support One Health approaches and advance the translational impact of microbiome research are particularly encouraged.

Background: This study aims to delineate the present and projected suitable habitats for four dominant tick species in the Beijing–Tianjin–Hebei (BTH) region, providing a spatial basis for targeted tick-borne disease surveillance. Methods: We systematically reviewed the published literature and the Global Biodiversity Information Facility (GBIF) to compile tick occurrence records in the BTH region. A total of 167 geo-referenced occurrence records with verified coordinates were obtained for four dominant species: Haemaphysalis longicornis, Haemaphysalis concinna, Dermacentor silvarum, and Ixodes persulcatus. The MaxEnt model was applied with bioclimatic variables (WorldClim, 2.5 arc-min), elevation, slope, aspect, and NDVI. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC) for within-species comparisons, complemented by the True Skill Statistic (TSS), Cohen’s kappa, and omission rate. Future projections (2021–2040, 2041–2060, 2061–2080, 2081–2100) were made under the SSP245 scenario using only climate variables, as the NDVI and topographic variables cannot be reliably forecast. Results: The four dominant tick species showed distinct distribution patterns: Hae. longicornis was widely distributed across the BTH region, whereas Hae. concinna, D. silvarum, and I. persulcatus were mainly found in the northern and northwestern mountainous areas. The primary environmental drivers were temperature, elevation, and the NDVI. MaxEnt models achieved good predictive performance (test AUC: 0.86–0.91; TSS: 0.72–0.88). Under future climate scenarios, suitable habitat centroids were projected to shift northwestward for Hae. longicornis (~57.6 km), D. silvarum (~71.1 km), and I. persulcatus (~50.0 km), and northeastward for Hae. concinna (~63.0 km) by 2081–2100. Conclusions: In this study, we identified current and future high-risk areas for four dominant tick species in the BTH region, providing a reproducible foundation for surveillance. Future projections should be interpreted with caution as they only account for climatic changes. Full article

Vacuum freeze-drying, commonly referred to as lyophilization, is one of the primary processes in vaccine industrial manufacturing. It offers significant advantages, including a marked extension of the shelf-life of dried products, effective preservation of biological activity, and user convenience. However, in the production of animal freeze-dried vaccines, the diverse nature of antigens, the complexity of heat-stable protectant formulations, and variations in manufacturing equipment pose substantial challenges to process design for animal freeze-dried vaccines. Commercially available animal freeze-dried vaccines commonly suffer from antigen potency loss, insufficient product stability, low production efficiency and high manufacturing costs. Freeze-drying process optimization can markedly improve the quality of freeze-dried vaccines, with key evaluation indicators including vaccine stability, shelf-life, sample morphology, and residual moisture content. Focusing on multiple types of animal vaccines, this review summarizes research advances in improving the quality of animal freeze-dried vaccines from the perspectives of modifying material properties, enhancing freezing-stage regulation, increasing the specific surface area for drying, and optimizing heat conduction. Finally, future research strategies for animal freeze-dried vaccines are prospected. Although numerous approaches have been proposed to enhance the quality of animal freeze-dried vaccines, comprehensive considerations from multiple dimensions are still required to provide more holistic theoretical support for cost reduction and efficiency improvement in the production of animal freeze-dried vaccines.
