Microbiota Diversity and Its Broader Biological Implications Across Human and Animal Health

Dear Colleagues,

Human and animal microbiota, consisting of bacteria, viruses, fungi, and other microbes, play a crucial role in regulating immune function, metabolism, and tissue homeostasis. These diverse communities inhabit various body sites, including the gut, skin, and reproductive organs, influencing health outcomes in both humans and animals. Recent research has expanded our understanding of microbiota's impact on metabolic regulation, reproductive function, etc. However, considerable variability across individuals complicates the establishment of a "healthy" microbiota and the determination of causal relationships between microbiota composition and health. Dysbiosis, or microbial imbalance, is linked to conditions like obesity, diabetes, and infertility. Environmental factors, such as diet and exposure to endocrine-disrupting chemicals, can exacerbate dysbiosis, influencing health. Although advances in sequencing technologies provide deeper insights, challenges remain in understanding microbiota–host interactions. We invite you to contribute high-quality research related to human and animal microbiota and its impact on health, using innovative methods such as original articles, large-scale observational studies, narrative and systematic reviews and perspectives. All submitted papers will undergo a rigorous peer-review process. We look forward to receiving your submissions and advancing our understanding of the microbiota's role in human and animal health.
