Infections of intact and damaged skin barriers and keratin are frequently associated with complex biofilm communities containing bacteria and fungi, yet there are limited options for successful management. This study intended to focus on the utility of some novel proprietary lactam molecules, quorum sensing (QS)-derived halogenated furanones, which act to block the QS pathway, against key fungal pathogens of the skin (Candida albicans, Malassezia furfur and Microsporum gypseum). Moreover, we aimed to assess how these actives performed against complex interkingdom biofilms in a clinically relevant model.

A niche in the context of microorganisms defines the specific ecological role or habitat inhabited by microbial species within an ecosystem. For the human commensal Malassezia, the skin surface is considered its primary niche, where it adapts to the skin environment by utilising lipids as its main carbon and energy source. However pathogenic characteristics of Malassezia include the production of allergens, immune modulation and excessive lipid utilisation, which result in several diseases such as pityriasis versicolor, seborrheic dermatitis, Malassezia folliculitis and atopic dermatitis.

Canine atopic dermatitis (cAD) and feline atopic skin syndrome are inflammatory and pruritic skin diseases with both environmental and genetic factors. Genetic factors may include barrier defects and a predisposition to mount T helper 2 lymphocyte immune response when allergens are encountered. These diseases have repeatable patterns of skin and ear inflammation and commonly lead to Staphylococcal and Malassezia skin and ear infections.

Mycoses
December 2024
Working Group on Mycoses in DRC, Kinshasa, Democratic Republic of the Congo.
Background: Although cutaneous mycoses are a global public health problem, very few data are available in the Democratic Republic of Congo (DRC).
Objectives: This study aimed to describe the retrospective clinical epidemiology of dermatomycosis and their associated risk factors in dermatological consultations in Kinshasa, DRC.
Methods: A retrospective study based on the medical records of patients seen in the departments of dermatology of 2 major hospitals in Kinshasa from March 2000 to August 2023 was carried out.
Demographic and Pathogen Profiles of Superficial Fungal Infections-A Single-Centre Observational Study in Poland.
Mycoses
December 2024
Department of Dermato-Venereology, 4 Th Military Hospital, Wroclaw, Poland.
Background: Superficial fungal infections (SFI) are contagious conditions affecting the skin and its appendages, caused by various fungal species. Monitoring the distribution of common pathogens and identifying at-risk patient groups are essential for effective management and prevention.
Objectives: This study investigates the characteristics of SFI in Poland's Malopolska region from 2017 to 2019, focusing on etiological agents, infection sites and risk factors.
