Article Abstract
The skin microbiome plays a pivotal role in the production of attractive cues detected by mosquitoes. Here, we leveraged recent advances in genetic engineering to significantly reduce the production of L-(+)-lactic acid as a strategy to reduce mosquito attraction to the highly prominent skin commensals and Engraftment of these engineered bacteria onto the skin of mice reduced mosquito attraction and feeding for up to 11 uninterrupted days, which is considerably longer than the several hours of protection conferred by the leading chemical repellent N,N-diethyl-meta-toluamide. Taken together, our findings demonstrate engineering the skin microbiome to reduce attractive volatiles represents an innovative untapped strategy to reduce vector attraction, preventing bites, and pathogen transmission. These findings set the stage for new classes of long-lasting microbiome-based repellent products.

Research Question: What is the composition of bacterial communities at various genital sites and are there potential interactions between partners' microbiota?
Design: This observational study involved metagenomic analyses of samples collected from male and female partners of couples undergoing fertility treatment. Samples included vaginal and penile swabs, as well as follicular fluid and semen, which were analysed using next-generation sequencing.
Results: The bacterial community profiles of different genital tract niches were distinct, niche-specific compositions, with female samples predominantly featuring Lactobacillus species and male samples displaying greater microbial diversity, including genital-specific and skin-associated taxa.

The epidermal immune microenvironment is a multifaceted system in which the interplay between the skin microbiome and antimicrobial peptides plays a pivotal role in sustaining skin homeostasis and preventing dysbiosis. Disruption of these interactions can lead to inflammatory skin conditions such as atopic dermatitis. This review aims to explore the complex mechanisms by which antimicrobial peptides and the skin microbiome communicate within the epidermal immune microenvironment, emphasizing causal dynamics and the dual role of antimicrobial peptides.

Topical antibiotics and antiseptics may decrease bacterial pathogens, but lack positive effects on microbiome diversity.
Methods: In this double-blind, intraindividual vehicle-controlled pilot study, n = 20 patients received a gel containing a defined extract (Spiralin®) of the microalgae Spirulina platensis, previously shown to exert anti-microbial effects, or vehicle on target lesions of similar size and clinical activity.

Objective: One of the possible causes of skin microbiome imbalance is the use of dermocosmetics with inadequate pH. This study aims to critically evaluate several children's moisturizers regarding their characteristics so that we can verify the tendency of the products available on the market and whether they are slightly acidic. The importance of dermocosmetics formulated without ingredients with allergenic potential is also discussed in this work.

Background: Multidrug-resistant bacterial infections have high mortality rates and few treatment options. Synergistic combinations may improve clinical outcome but traditional strategies often damage healthy microbiome. Oxazolidinone-class antibiotics are typical last-resort drugs for treating drug-resistant bacterial infections but are becoming less effective due to resistance development.
