Isolation and Identification of the Follicular Microbiome: Implications for Acne Research

Our understanding of the microbiome and the role of P. acnes in skin homeostasis and acne pathogenesis is evolving. Multiple methods for sampling and identifying the skin's microbiome exist and understanding the differences between the abilities of various methods to characterize the microbial landscape is warranted. This study compared the microbial diversity of samples obtained from the cheeks of twenty volunteers, collected by surface swab, pore strips, and cyanoacrylate glue follicular biopsy.

The balance of metagenomic elements shapes the skin microbiome in acne and health

Studies have emphasized the importance of disease-associated microorganisms in perturbed communities, however, the protective roles of commensals are largely under recognized and poorly understood. Using acne as a model disease, we investigated the determinants of the overall virulence property of the skin microbiota when disease- and health-associated organisms coexist in the community.

Efficacy and local tolerability of different spray products in the treatment of mild to moderate acne of the back and chest. A controlled, 3-arm, assessor-blinded prospective trial

A spray formulation containing 2 vitamin-A derivatives (hydroxypinacolone retinoate and retinol) carried in glycospheres (RetinSphere®) combined with an antimicrobial peptide (BIOPEP-15), salicylic acid and vitamin E (BR) has been recently developed for the treatment of truncal acne.

A Precision Microbiome Approach Using Sucrose for Selective Augmentation of Staphylococcus epidermidis Fermentation against Propionibacterium acnes

Acne dysbiosis happens when there is a microbial imbalance of the over-growth of Propionibacterium acnes (P. acnes) in the acne microbiome. In our previous study, we demonstrated that Staphylococcus epidermidis (S. epidermidis, a probiotic skin bacterium) can exploit glycerol fermentation to produce short-chain fatty acids (SCFAs) which have antimicrobial activities to suppress the growth of P. acnes.

Patterns of antimicrobial resistance in lesions of hidradenitis suppurativa

Antibiotic therapy is commonly used to treat hidradenitis suppurativa (HS). Although concern for antibiotic resistance exists, data examining the association between antibiotics and antimicrobial resistance in HS lesions are limited. We sought to determine the frequency of antimicrobial resistance in HS lesions from patients on antibiotic therapy.

Comparison of TLR-2, TLR-4, and antimicrobial peptide levels in different lesions of acne vulgaris

Recent studies have shown that tolls like receptors (TLRs) and antimicrobial peptides (hBD-1, cathelicidin) play an important role in the pathogenesis of acne vulgaris (AV). Objective: To evaluate and report the expression of TLR-2, TLR-4, hBD-1 and cathelicidin in different regions of skin in AV.
