Summary: The skin is a diverse ecosystem that houses a variety of microorganisms. This study investigated the variability of the skin microbiome and skin biophysical parameters according to season over the course of one year. The research found that the composition of the skin microbiome fluctuated with the seasons and showed significant associations with skin characteristics, such as skin barrier function.

Summary: The major challenge in working with longitudinal data is that differences in pace and dynamics might overshadow similarities between processes. Using the approach of temporal alignment can help in understanding the link between the microbiome and the host.

Summary: The study reveals that healthy equine skin harbors a diverse microbiota, with individuals in similar environments sharing overlapping microbial populations on their skin. These populations vary significantly over time and between different body sites.

Summary: The study found that single applications of CHG have minimal impact on the epidermal microbiota, with long-term effects being unlikely. The epidermal microbiota showed remarkable intrasubject stability in the same individuals, even over extended periods of time.

Summary: This study aimed to assess the variation in the upper respiratory tract microbiome using saliva specimens in a cohort of individuals with primarily mild to moderate disease. The results showed that the salivary microbiome remained stable in unexposed individuals over the study period, and participants with mild to moderate SARS-CoV-2 infection showed microbiome stability throughout and after their infection. However, severe SARS-CoV-2 infection was associated with temporary reductions in microbiome diversity, indicating the limits of microbiome resilience in the face of severe infection.

Summary: Urban living can cause various skin disorders, with the skin microbiome playing a key role in urbanization-related skin alterations. The connectivity and fragility of individual microbiome networks (MNI) significantly mediate the adverse effects of air pollution on skin health, while smoking habits deepen the negative impact of pollution on facial skin microbiota.

Summary: By analyzing stool samples of infants and young children, the authors found that there are changes in fungal composition and abundance at weaning, but overall fungal diversity remains relatively constant over time. Fungal composition is influenced by geography, diet, and the use of probiotics. The study also showed subtle fungal differences between children who developed autoimmune diseases and those who did not.

Summary: Decolonization with topical antimicrobials disrupts bacterial communities on the skin, with effects differing between younger and older subjects. The disruption can persist for up to a year post-intervention.

Summary: This study conducted shotgun metagenomic sequencing on fecal samples from healthy individuals in Vietnam and found a significant presence of antimicrobial resistance (AMR) genes in the gut microbiome, especially in young children. These genes could be transferred to pathogens, contributing to the generation of multidrug-resistant and extensively drug-resistant pathogens. Longitudinal cohort studies in urban and rural areas of developing countries are suggested to further understand the behavior of these AMR reservoirs.

Summary: The study found that daily use of skincare products can increase bacterial diversity in facial skin, change the microbial community, increase the relative abundance of bacteria such as Cutibacterium and Staphylococcus, and improve skin hydration and texture.

Summary: Cutibacterium acnes is the most abundant bacterium living in healthy human skin, playing a significant role in skin homeostasis and related skin disorders. Its contribution to normal skin functions through lipid modulation, niche competition, and oxidative stress mitigation highlights its importance in skin health. Limited studies have explored the potential of skin probiotics using skin commensal strains, compared to gut probiotics.

Summary: The study revealed that gut-related bacteria remain stable in the sacral skin of bedridden patients, despite efforts made by patients to restore skin physiological functions through daily skin care. The only significant change observed over 2 years was a decrease in skin pH, approaching normal levels.

Summary: The pilot study identified a diverse range of Corynebacterium species on human skin, including previously unreported species. The study revealed individual variations in biochemical and resistance profiles among the strains. This highlights the importance of cultivation-based studies in understanding the properties of these microorganisms.
