Intracellular pathogens including Staphylococcus aureus contribute to the non-healing phenotype of chronic wounds. Lactobacilli, well known as beneficial bacteria, are also reported to modulate the immune system, yet their role in cutaneous immunity remains largely unknown. We explored the therapeutic potential of bacteria-free postbiotics, bioactive lysates of lactobacilli, to reduce intracellular S.

Health disparities can be experienced by any disadvantaged group who has limited access to healthcare or decreased quality of care. Quality of care can be measured by physician-patient communication measures such as length of visit, health outcomes, patient satisfaction, or by the services one receives such as screening or health education. This study aims to determine the relationship between length of physician-patient encounter, number of preventive services, ethnicity, and race.

Objective: To discuss the skin microbiome modulates immunity by interactions between skin immunology with keratinocytes to combat pathogens. Allergic disorders are classified by immunoglobulin E sensitivity and aberrant T2 cell responses, and an increasing number of studies have described the associations with skin microbiome fluctuations. In this review, we discuss commensal-epidermal homeostasis and its influence on allergic disease.

Introduction: Hispanic/Latino populations are more likely to have extensive psoriasis than the non-Hispanic/Latino population. Biologics are indicated for moderate/severe psoriasis or psoriasis with comorbidities. No studies have assessed ethnicity as a predictor of biologic utilization.

Background: Atopic dermatitis (AD) patients are often colonized with Staphylococcus aureus, and staphylococcal biofilms have been reported on adult AD skin lesions. The commensal S epidermidis can antagonize S aureus, although its role in AD is unclear. We sought to characterize S aureus and S epidermidis colonization and biofilm propensity and determine their associations with AD severity, barrier function, and epidermal gene expression in the first US early-life cohort of children with AD, the Mechanisms of Progression of Atopic Dermatitis to Asthma in Children (MPAACH).

Background: Nonlesional skin in atopic dermatitis (AD) is abnormal, but the pathobiology of lesional and nonlesional skin and the definition of endotypes are poorly understood.

Objective: To define lesional and nonlesional endotypes of AD by building the first US-based early-life prospective cohort of children with AD, the Mechanisms of Progression from AD to Asthma in Children cohort.

Methods: We assessed lesional and nonlesional skin transepidermal water loss, filaggrin (FLG) and alarmin (S100A8, S100A9) expression, staphylococcal colonization, and patterns of aeroallergen and food sensitization to define nonlesional and lesional phenotypes and endotypes.

Mucosal barriers are densely colonized by pathobiont microbes such as Candida albicans, capable of invasive disseminated infection. However, systemic infections occur infrequently in healthy individuals, suggesting that pathobiont commensalism may elicit host benefits. We show that intestinal colonization with C.

Infective endocarditis (IE) is associated with high morbidity and mortality rates. The predominant bacteria causing IE is Staphylococcus aureus (S. aureus), which can bind to existing thrombi on heart valves and generate vegetations (biofilms).

Purpose Of Review: Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disorder that is a major public health burden worldwide. AD lesions are often colonized by Staphylococcus aureus and Staphylococcus epidermidis. An important aspect of Staphylococcus spp.

Article Synopsis
  • Escherichia coli lipoprotein (Lpp) exists in two forms: bound-form, which interacts with the cell wall, and free-form, which is found on the bacterial surface, with unclear functions for the latter.
  • Researchers hypothesized that surface-exposed Lpp could bind to plasminogen (Plg), a protease used by several important bacteria, and conducted experiments to explore this interaction and its biochemical implications.
  • The study found that Lpp can bind Plg, potentially through a hidden domain on Lpp, and that the binding allows the conversion of Plg to active plasmin, leading to further questions about Lpp's role in bacterial infections and interactions with the host.

Article Synopsis
  • The study focuses on Borrelia burgdorferi, the bacterium causing Lyme disease, and its fibronectin-binding protein BB0347, which may play a key role in disease development.
  • BB0347 is expressed on the surface of the bacterium, suggesting it could be significant in how the bacteria interact with human fibronectin.
  • Further research is required to fully understand BB0347's role in the infection process of Lyme disease.

Article Synopsis
  • Previous research shows that the RevA outer surface protein of the Lyme disease bacterium, Borrelia burgdorferi, plays a role in mammalian infections and is a potential target for vaccines due to its conserved nature across Lyme strains.
  • Mice infected with B. burgdorferi produced antibodies against RevA, which remained high for over a year, indicating ongoing immune recognition of the protein; however, vaccination with RevA did not prevent infection.
  • While RevA-based vaccines didn't protect against infection in mice, using antibodies against RevA effectively prevented the disease, highlighting the potential for immunotherapy based on RevA.
