Article Synopsis
- The study examines the relationship between skin oxylipins, which are bioactive lipids produced from fatty acids by skin microbes, and different microbial communities on the skin of children and adults.
- Findings highlighted that Malassezia restricta, a type of skin fungus, has a positive impact on the production of a specific oxylipin (9,10-DiHOME) in adults, while showing a negative correlation with its precursor in children, indicating differences in skin chemistry across age groups.
- The research suggests a complex communication system between skin microbes and host lipid metabolism that could have implications for skin health, emphasizing the need for further exploration of these interactions for potential therapeutic applications.

species constitute the most common cause of fungal infections in humans; the emergence of resistance and biofilm formation by species further threaten the limited availability of antifungal agents. Over the past decade, . has caused significant outbreaks worldwide and has emerged as a human pathogenic fungus that causes diseases ranging from superficial to life-threatening disseminated infections.

Candida albicans is a common opportunistic pathogen, causing infections ranging from superficial to bloodstream infections. The limited antifungal options and rising drug resistance challenge clinical treatment. We screened 98 essential oils and identified 48 with antifungal activity against Candida albicans at 1% concentration, determining their minimum inhibitory concentrations (MIC).

Fungal infections have become a growing public health concern, aggravated by the emergence of new pathogenic species and increasing resistance to antifungal drugs. The most common candidiasis is caused by ; however, has become an emerging opportunistic pathogen, and although less prevalent, it can cause superficial and systemic infections, especially in immunocompromised individuals. This yeast can colonize the oral cavity, skin, and other tissues, and has been associated with oral infections in patients with human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS), making it difficult to treat.

Thiamine dilauryl sulphate (TDS) exerts a bacteriostatic effect against Gram-positive bacteria and is used as a food additive. The heartwood extract of the Indian kino tree (Pterocarpus marsupium), a medicinal tree native to India, shows weak antimicrobial effects against bacteria and superficial dermatophyte-infective fungi. Herein, we report that the combination of TDS and P.
