Members of the genus Malassezia are lipophilic basidiomycetous yeasts, which are part of the normal cutaneous microbiota of humans and other warm-blooded animals. Currently, this genus consists of 14 species that have been characterized by phenetic and molecular methods. Although several molecular methods have been used to identify and/or differentiate Malassezia species, the sequencing of the rRNA genes and the chitin synthase-2 gene (CHS2) are the most widely employed. There is little information about the β-tubulin gene in the genus Malassezia, a gene has been used for the analysis of complex species groups. The aim of the present study was to sequence a fragment of the β-tubulin gene of Malassezia species and analyze their phylogenetic relationship using a multilocus sequence approach based on two rRNA genes (ITS including 5.8S rRNA and D1/D2 region of 26S rRNA) together with two protein encoding genes (CHS2 and β-tubulin). The phylogenetic study of the partial β-tubulin gene sequences indicated that this molecular marker can be used to assess diversity and identify new species. The multilocus sequence analysis of the four loci provides robust support to delineate species at the terminal nodes and could help to estimate divergence times for the origin and diversification of Malassezia species.

Objected: Mal f 1, the first allergen cloned from Malassezia furfur, has been found to have positive IgE reactivity in sera from patients with skin inflammation. In vitro, it has also been shown to induce maturation of dendritic cells and release inflammatory factors. However, its role in skin lipid homeostasis remains largely unexplored.

Malassezia furfur is the primary etiological agent of dandruff (Pityriasis capitis). Although herbal shampoos are preferred for their natural, mild ingredients over synthetic counterparts, they are often perceived as less effective in managing flaky scalp conditions or furfuration causing dandruff. The study compares the antifungal efficacy of herbal and synthetic shampoos against M.

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.
