Prior studies from Dr Richard Novick's group have established the central role of agr quorum sensing signaling in S. aureus skin pathogenesis by several notable observations (Parlet et al., 2019), implying that the quorum sensing interaction may lead to disease or promote remissions. Composition of Human Skin Microbiota Affects Attractiveness to Malaria Mosquitoes. 10:2730. doi: 10.1038/s41467-019-10646-7, Bolotin, A., Quinquis, B., Sorokin, A., and Ehrlich, S. D. (2005). Association between Staphylococcus aureus nasal carriage and disease phenotype in patients affected by systemic lupus erythematosus. As a result, the novel concept of restoring the composition and functionality of the skin microbiota to the previous indigenous state by targeted manipulation of the skin microbiota, on the basis of the skin ecosystem, has been proposed as a potential therapeutic approach in the last few years (Paetzold et al., 2019; Stacy and Belkaid, 2019). Although research on the skin microbiota lags behind studies of gut flora, there are already some applications for ecology-based therapy with the aim of correcting the imbalances on the cutaneous ecosystem. A. Whole metagenome profiling reveals skin microbiome-dependent susceptibility to atopic dermatitis flare. 40, 873–876. Noteworthy, Malassezia species (such as Malassezia dermatitis and Malassezia sympodialis) were enriched in AD-prone skin by whole metagenome profiling (Casagrande et al., 2006; Chng et al., 2016), suggesting that the relative abundance of Malassezia species shifts in association with the AD disease course. A., Irvine, A. D., and Foster, T. J. A randomized synbiotic trial to prevent sepsis among infants in rural India. To date, two of the 0.2–0.4-mm-long mite species are known to inhabit human skin. 137, 1213–1214. Of note, heterogeneous S. epidermidis strain communities in less severe AD flares are genomically similar to nosocomial strains that are a leading cause of mortality of sepsis in newborn infants (Meisel et al., 2016). In another in vitro study, two clinical isolates of C. acnes type IA and IB significantly induced the expression of β-defensin-2 in human sebocytes and keratinocytes (Nagy et al., 2005, 2006). Skin microbiota analysis. Additionally, a recent study shows that Malassezia globosa can secrete protease that attenuates S. aureus biofilm associated with increased severity and barrier dysfunction of the progression of AD (Li et al., 2018). Recent work provided evidence that patients with AD have an increased likelihood of developing asthma, allergic rhinitis, and chronic sinusitis with nasal polyposis, which were previously regarded as a symbol of overall immune-system dysfunction (Thaçi et al., 2016; Sohn, 2018).

However, the diversity and relative abundance of the body's microbial communities vary in both the individual and the physiology of the skin sites, which has been categorized into four major skin microenvironment: oily, moist, dry, and foot (Figure 1; Belkaid and Segre, 2014; Byrd et al., 2018). Bacterial colonization and succession in a newly opened hospital. The skin condition is clinically characterized by intense pruritus, relapsing eczematous lesions, and a fluctuating course (Eyerich et al., 2015; Geoghegan et al., 2018), whose manifestations not only have a substantial effect on quality of life by sleep deprivation and profoundly diminished self-esteem (Simpson et al., 2016; Weidinger et al., 2018) but also increase the risk of infection and other atopic disorders (Thaçi et al., 2016). 2020 Feb 26;11:291. doi: 10.3389/fmicb.2020.00291. According to the top 10 most abundant ribotypes (RT) showing healthy and acne-specific associations, the three most abundant ribotypes (RT1, RT2, and RT3) had a similar relative abundance and evenly distributed in acne and normal pilosebaceous units (Fitz-Gibbon et al., 2013; O'Neill and Gallo, 2018). The predominant species of CoNS with antimicrobial activity were identified as S. epidermidis and Staphylococcus hominis, although many strains of the CoNS species did not produce antimicrobial activity.

The additional observation that distinct strains of C. acnes may differ in contribution to the pathogenesis of AV raises the exciting possibility that investigators need to identify C. acnes at the strain level with a greater potential to be implicated in the condition (Nagy et al., 2006). The result uncovered a more than 90% decrease in the number of S. aureus on their skin by a single application. Multi-ancestry genome-wide association study of 21,000 cases and 95,000 controls identifies new risk loci for atopic dermatitis.

Commensal staphylococci influence Staphylococcus aureus skin colonization and disease. Michalik M, Samet A, Podbielska-Kubera A, Savini V, Międzobrodzki J, Kosecka-Strojek M. Ann Clin Microbiol Antimicrob. (2019). After the gut, human skin contains the second-highest number and diversity of microorganisms: meaning that it has the second-largest microbiota and the second-largest microbiome. The skin is home to a wide variety of normal microbiota, consisting of commensal organisms that derive nutrition from skin cells and secretions such as sweat and sebum. This skin microbiota is of high importance for human health and well-being. Healthy human skin microbiome has a huge impact on how our skin looks and feels. Rev. Coagulase-negative staphylococci (CoNS) as a significant etiological factor of laryngological infections: a review. The human skin is a complex ecosystem that hosts a heterogeneous flora. For example, the appearance of AD has been tightly associated with dysbiosis in the skin microbiota (Kobayashi et al., 2015). It is implicated in several severe skin diseases and plays a major role in wound infections. doi: 10.1038/sj.jid.5700431, Chaptini, C., Quinn, S., and Marshman, G. (2016). The human skin is densely colonized by a highly diverse microbiota comprising all three domains of life.

Spore formation is uncommon, particularly among abundant species, which are five times less likely to sporulate than skin microbes in general. Drug Discov. Finally, the analysis of structure and function of the human skin microbiota is interesting from a basic, evolutionary perspective on human microbe interactions.Key questions in the field of skin microbiota research deal with (a) a deeper understanding of the structure (species inventory) and function (physiology) of the healthy human skin microbiota in space and time, (b) the distinction of resident and transient skin microbiota members. (2016). 2, 799–808. Human skin microbiota has been described as a “microbial fingerprint” due to observed differences between individuals. Current understanding of the cutaneous microbiota is based on sampling the outermost layers of the epidermis, while the microbiota in the remaining skin layers has not yet been fully characterized. doi: 10.2147/CCID.S69135, Mortz, C.

Updates on the epidemiology of dermatophyte infections. J. (2018). Microbiol. Rev. Clin. The skin is the human body's largest organ, colonized by a diverse milieu of microorganisms, most of which are harmless or even beneficial to their host. With an increasing appreciation in the contribution of microbes to skin diseases, ecology-based therapy of microbial transplantation that exploits the preferred niche of skin microbiota has also been developed for the treatment and study of diseases. (2019). Infect. Four most prominent bacterial taxa (Actinobacteria, Firmicutes, Bacteroidetes, and Proteobacteria) and the Staphylococcaceae (a Firmicute) are found on the surface of healthy skin. Many less severe, but negatively perceived cosmetic skin phenomena are linked with skin microbes, too. PLoS ONE 5:e12277. (2017). AD (also known as eczema) is a paradigmatic chronic inflammatory cutaneous disease that affects 10–30% of children in industrialized countries and has a lifetime prevalence of up to a fifth of the population in the developed world (Weidinger and Novak, 2016; Tsakok et al., 2018; Guttman-Yassky et al., 2019). Skin microbiota-host interactions. Most microbiome studies concentrate on understanding bacterial composition, but the microbes present in human skin habitats are not limited to bacteria. In longitudinal surveys of a cohort of pediatric AD patients, shotgun metagenomic sequencing of clinical skin sample throughout the disease course revealed that bacterial communities shifted markedly in this cohort, although the fungal or viral components had no significant differences over time (Byrd et al., 2017). 22, 385–386. Allergy 68, 498–506. The unique genome regions of acne-enriched RT4 and RT5 strains are implicated in a linear plasmid (loci 3) encoding a tight adhesion (Tad) locus in relation to virulence affecting bacterial adhesion and host immune responses and two unique loci of genomic islands (loci 1 and 2) encoding a Sag gene cluster in association with hemolytic activity in pathogens (Fuller et al., 2002; Humar et al., 2002; Tomich et al., 2007; Fitz-Gibbon et al., 2013; Kasimatis et al., 2013). Several notable observations that the composition of the skin microbiota in acne is disturbed highlight the importance of studying diseases in the context of the microbial dysbiosis (Lomholt and Kilian, 2010; Fitz-Gibbon et al., 2013). The human skin microbiome has recently become a focus for both the dermatological and cosmetic fields. Human commensals producing a novel antibiotic impair pathogen colonization. (2011). Acad. Adv.

These microbes that coexist in an established balance play a pivotal role in the protection of cutaneous health and the orchestration of skin homeostasis. J. Interspecies interactions influence the composition of microbial communities, but their mechanisms are poorly understood. As such, these flares in eczema patients are thought to be driven by S. aureus skin colonization and exacerbating eczema flare-ups are associated with an increase in the number of S. aureus on affected region and a decrease in S. epidermidis that produce S. aureus-targeting bacteriocins. The diversity of bacteria is vary based on the different locations of our skin. There are present different types of bacteria on our skin surface. The severity of AV clinical symptoms depends on the number of non-inflammatory lesions (closed and open comedones), inflammatory lesions (pustules and papules), and the residual pathology of nodules and cysts (Shalita, 2004; Ghodsi et al., 2009). doi: 10.1186/2045-7022-4-33, Scharschmidt, T.
