Dermatophytes cause most superficial mycoses in humans and animals. Their pathogenicity is probably linked with the secretion of proteins degrading keratinised structures. Using 2D-PAGE and a shotgun mass spectrometry approach, we identified 80 proteins from Trichophyton rubrum and Trichophyton violaceum secretomes, under conditions mimicking those in the host. Identified proteins included endo- and exoproteases, other hydrolases, and oxidoreductases. Our findings can contribute to a better understanding of the virulence mechanisms of the two species and the different types of infection they cause.

Objectives: Tinea capitis remains a common fungal infection in children worldwide. Species identification is critical for determining the source of infection and reducing transmission. In conventional methods, macro- and microscopic analysis is time-consuming and results in slow fungal growth or low specificity.

Keratinophilic fungi, or dermatophytes, are recognized as the predominant fungal agents responsible for superficial skin diseases globally. The identification of species of dermatophytes is crucial for both therapeutic and epidemiological considerations. The primary objective of the present study was to investigate the epidemiology of dermatophytosis among patients who sought medical attention at the medical mycology laboratory in Golestan province.

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.

Fungi can remarkably sense and adapt to various extracellular stimuli and stress conditions. Oxidative stress, which results from an imbalance between reactive oxygen species production and antioxidant defenses, leads to cellular damage and death. In , oxidative stress is managed by a complex antioxidant system, including thioredoxins, glutathione, catalases, peroxidases, and superoxide dismutase, with glutathione playing a crucial role.

Background: Dermatophytosis is a major public health concern in India, especially in recent years, with an alarmingly rising trend, particularly in relation to recurrent and chronic infection. The number of studies examining the relationship between an individual's glycemic status and the development of dermatophytosis, and a comparison of the evolving species trend between diabetic and non-diabetic patients infected with dermatophytes, is limited.
Aims And Objectives: To study and compare the clinical and mycological aspects of dermatophytosis among diabetic and non-diabetic patients and to compare the culture isolates in both groups.
