The intricate ecosystem of the skin microbiome plays a pivotal role in the pathogenesis of Atopic Dermatitis (AD). Recent research titled "Preliminary Characterization of Skin Microbiota and Mycobiota in Atopic Dermatitis by Metagenomic and Culture-Based Analyses" underscores the necessity of combining high-resolution shotgun metagenomics with traditional culture techniques to fully understand microbial dysbiosis. For researchers and pharmaceutical developers in the Live Biotherapeutic Product (LBP) space, these findings provide a roadmap for identifying therapeutic targets. Creative Biolabs, as a leading CRO in microbiome research, offers a comprehensive suite of services and products designed to accelerate the transition from microbial discovery to clinical application. By leveraging our specialized platform, partners can efficiently navigate the complexities of skin-resident bacteria and fungi, ensuring the development of robust, evidence-based dermatological interventions.

Overview: The Landscape of Skin Microbiota and Mycobiota in AD
The study in question investigates the skin microbiome's composition and functional potential in patients with Atopic Dermatitis (AD) compared to healthy controls. AD is characterized by skin barrier dysfunction and recurrent inflammation, often linked to microbial imbalances. The experimental methodology merged high-throughput metagenomic sequencing with classical, culture-based culturomic analysis to provide a balanced overview of the cutaneous ecosystem:
-
Culturomic Findings: The culture-based isolation successfully identified 42 distinct bacterial species and 6 fungal species. Notably, Staphylococcus aureus and Candida parapsilosis emerged as the predominant cultivable taxa across the patient cohort.
-
Metagenomic Sequencing Data: High-throughput molecular profiling revealed that Staphylococcus spp. and Malassezia spp. represented the dominant bacterial and fungal genera, respectively, while exhibiting substantial inter-individual variability.
-
Probiotic-Associated Variations: While regular oral probiotic use demonstrated no statistically significant impact on the alpha or beta diversity of the skin bacterial microbiota, it was associated with significant alterations in the skin mycobiota. Probiotic users exhibited higher fungal species richness and evenness (alpha and beta diversity metrics). At the species level, Malassezia restricta was more prevalent among probiotic users, whereas Candida parapsilosis and Rhodotorula mucilaginosa were notably enriched in the non-probiotic group.
The study concludes that AD is associated with a profound reduction in microbial diversity and a shift in both bacterial and fungal community structures. The integration of metagenomics and culture-based methods is essential for a holistic understanding of the skin ecosystem and for the identification of potential LBP candidates that can restore microbial homeostasis.
Targeted CRO Service Solutions Based on Research Workflows
To build upon the research findings described above, developers require precise analytical tools and laboratory capabilities. Creative Biolabs translates these research requirements into structured CRO services:
Integrated Skin Microbiome & Mycobiome Sequencing
Evaluating dual-kingdom dynamics requires robust DNA extraction protocols capable of lysing both thick-walled fungal spores and fragile bacteria. We offer:
-
Metagenomic Shotgun Sequencing & 16S/ITS Amplicon Sequencing: Specialized pipelines for simultaneous bacterial (16S rRNA) and fungal (ITS/18S) profiling from low-biomass skin swabs.
-
Advanced Bioinformatic Pipelines: High-resolution taxonomic assignment, alpha/beta diversity profiling, and multi-omic correlation analysis to map host-microbe interactions.
High-Throughput Culturomics & Strain Isolation
Moving from sequencing data to functional validation requires isolating living strains. Our custom culturomics services provide:
-
High-throughput isolation of skin-resident bacteria and fungi.
-
Utilization of anaerobic, aerobic, and specialized media (e.g., Dixon's agar for Malassezia) to capture fastidious organisms.
-
Strain identification via MALDI-TOF MS and 16S/ITS/WGS sequencing.
In Vitro & In Vivo Functional Characterization
Understanding how a probiotic or LBP modulates the skin barrier or suppresses pathogens requires robust validation models:
-
Co-culture & Efficacy Assays: Testing LBP candidates against clinical isolates of S. aureus or Candida parapsilosis to measure antimicrobial, anti-inflammatory, or barrier-reinforcing activities.
-
Skin Barrier Animal Models: Evaluation of LBP candidates in AD mouse models to determine tissue-level immune responses, epidermal thickness, and systemic cytokine modulation.

Frequently Asked Questions (FAQs)
Why is shotgun metagenomics preferred over 16S rRNA sequencing for skin microbiome studies?
Skin samples often have low microbial biomass. Shotgun metagenomics provides higher taxonomic resolution (to the strain level) and captures fungal and viral components, whereas 16S is limited to bacteria and often lacks the resolution to distinguish closely related skin commensals.
How does Creative Biolabs handle the high level of human DNA contamination in skin samples?
We utilize specialized host DNA depletion kits and bioinformatic filters to ensure that the majority of sequencing reads are derived from the microbial community, maximizing data quality and cost-effectiveness.
Can you assist in isolating a specific strain identified in a metagenomic study?
Yes. Our culturomics platform is designed to transition from "sequence to isolate." By using the metabolic profile predicted by metagenomics, we can tailor culture conditions to increase the likelihood of isolating specific target strains.
