Summary
Human skin microbial communities are primarily shaped by the individual, not the environment. This study maps skin metagenomes over time to reveal long-term stability drivers.
Area of Science:
- Microbiology
- Genomics
- Human Microbiome
Background:
- The human skin microbiome plays a crucial role in health and disease.
- Understanding the stability and drivers of skin microbial communities is essential for developing targeted interventions.
- Previous studies have explored skin microbial composition, but long-term dynamics remain less understood.
Purpose of the Study:
- To investigate the temporal stability of the human skin metagenome.
- To identify the primary factors influencing the composition of skin microbial communities over time.
- To provide insights into the resilience and adaptability of the skin microbiome.
Main Methods:
- Metagenomic sequencing of skin samples from individuals over an extended period.
- Bioinformatic analysis to assess microbial community composition and diversity.
- Statistical modeling to determine the influence of host-specific and environmental factors.
Main Results:
- Skin microbial community composition is remarkably stable within individuals over time.
- Host-specific factors, rather than environmental influences, were found to be the dominant drivers of microbial community structure.
- Significant inter-individual variation in skin metagenomes was observed.
Conclusions:
- The human skin microbiome exhibits a high degree of personal stability, largely dictated by the host.
- These findings have implications for understanding skin health, disease pathogenesis, and the development of microbiome-based therapeutics.
- Future research should focus on elucidating the specific host factors that govern skin microbial community assembly.

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

01:27The Skin Microbiota
16
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

01:22Introduction to the Human Microbiota
28
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
