Shifting etiological agents of dermatophytosis: a molecular epidemiological study from Iran

mycolabadmin

Researchers in Iran studied fungal infections of the scalp and nails using modern DNA testing methods. They found that the main fungus causing scalp infections (T. tonsurans) remains the most common, but a new species (T. indotineae) is increasingly causing nail infections and is resistant to common antifungal medicines. The study shows that traditional identification methods often misidentify these fungi, highlighting the importance of molecular testing for accurate diagnosis and treatment.

A Case of Superficial Mycoses in a Patient with Systemic Lupus Erythematosus

A 52-year-old woman with lupus developed severe fungal skin infections that were initially mistaken for worsening lupus symptoms. Her condition improved after 6 months of treatment with two antifungal medications (terbinafine and itraconazole). This case reminds doctors that patients taking immunosuppressive medications for lupus are at high risk for fungal infections, which can be misdiagnosed as lupus flares.

Antifungal susceptibility testing of Microsporum canis isolated from the skin of dermatologically healthy cats

Researchers tested healthy cats in Chile and found that about 5% carried a fungus called Microsporum canis that can cause ringworm. This fungus was resistant to a common antifungal drug called fluconazole. Indoor cats were more likely to carry the fungus than outdoor cats. Because cats can spread this fungus to people, identifying carrier cats is important for preventing human infections.

Superficial Fungal Infections in the Pediatric Dermatological Population of Northern Poland

This study examined fungal skin infections in children and teenagers in northern Poland from 2019 to 2024. Researchers tested over 1,200 young patients and found that about 1 in 5 had a fungal infection. The most common culprits were specific fungi that cause scalp infections in young children and foot/nail infections in teenagers. Interestingly, children living in rural areas were more likely to have these infections, even though more urban children were tested.

SUB6 Subtilisin is Involved During the Initial Adhesion of Trichophyton benhamiae and T. mentagrophytes onto Reconstructed Human Epidermis

This study examined how a fungal protein called SUB6 helps dermatophytes (fungi causing ringworm) stick to human skin. Researchers used genetically modified fungi without SUB6 and found that these strains had difficulty initially attaching to skin but eventually infected it anyway. The results suggest SUB6 is a useful marker for detecting fungal infections but isn’t absolutely necessary for the fungus to cause disease.

The frequency distribution of Aspergillus section Nigri from clinical and environmental samples in Iran

mycolabadmin

Researchers studied black mold species (Aspergillus section Nigri) found in hospitals and the environment across Iran. They identified eight different species and found that certain types like A. welwitschiae were more common in ear infections while A. tubingensis was more prevalent in soil and air. These findings are important because some of these molds cause serious infections in humans and understanding where they live helps doctors predict and treat infections.

Superficial Fungal Infections in Children—What Do We Know?

mycolabadmin

Fungal infections of the skin, hair, and nails are increasingly common in children worldwide, especially in warm, humid climates and in crowded living conditions. These infections are caused by germs that live on the skin and can spread through contact with infected people or animals. Children are particularly vulnerable due to their developing immune systems, but most infections are treatable with topical creams or oral medications, with terbinafine being the most effective option currently available.

Addressing filamentous fungi-related onychomycosis in the era of antifungal resistance: assessment of Zataria multiflora nanostructured lipid carrier topical gel in a double-blinded clinical trial

mycolabadmin

Nail fungal infections (onychomycosis) are difficult to treat, especially as fungi become resistant to standard antifungal medications. Researchers tested a new gel made from Zataria multiflora (Shirazi thyme) packaged in special nanoparticles that help the medicine penetrate the nail better. In a clinical trial comparing this gel to placebo, the Zataria multiflora treatment showed better results after just 2 weeks, with 70% of patients experiencing fungal cure compared to 55% with placebo.

Deep learning application to hyphae and spores identification in fungal fluorescence images

mycolabadmin

Researchers developed an artificial intelligence system that can automatically identify fungal infections in microscope images as accurately as experienced doctors. The system uses two different AI models working together to spot fungal spores, thread-like hyphae, and mycelium in fluorescence images. This technology could significantly reduce the time doctors spend analyzing samples and help ensure more accurate diagnoses, especially in hospitals with fewer experienced specialists.

Etiological Agents and Predisposing Factors of Superficial Fungal Infections in Northeastern Argentina

mycolabadmin

Researchers studied fungal skin infections in a community in northeastern Argentina, finding that 37% of patients had these infections. The most common cause was a fungus called Trichophyton tonsurans. Poor living conditions like overcrowding and lack of clean water increased infection risk. The study shows that fungal skin infections are a significant health problem in areas with limited access to basic sanitation and water services.
