Emerging antifungal resistance in Trichophyton mentagrophytes: insights from susceptibility profiling and genetic mutation analysis

mycolabadmin

This study examined how common skin fungal infections caused by Trichophyton species are becoming resistant to standard antifungal treatments. Researchers tested 131 fungal isolates from China and analyzed their resistance genes to understand why some strains no longer respond to terbinafine and other antifungal drugs. They found that certain genetic mutations, particularly in the SQLE gene, make these fungi resistant to treatment and that different species have different resistance patterns. These findings help doctors better choose treatments and guide the development of new antifungal medications.

Emergence of resistant dermatophytosis caused by Trichophyton indotineae: First case series in Thailand

mycolabadmin

Researchers in Thailand have identified five patients with a difficult-to-treat fungal skin infection caused by Trichophyton indotineae, a type of dermatophyte that resists the commonly used antifungal drug terbinafine. This is the first time this resistant fungus has been detected in Thailand. The team developed a simple, inexpensive test using urease to help identify these resistant infections more easily. Patients responded well to the antifungal drug itraconazole after other treatments failed.

Epidemiology of Onychomycosis in the United States Characterized Using Molecular Methods, 2015–2024

mycolabadmin

This large study examined over 710,000 nail samples to identify which fungi cause nail infections in the United States. Using modern molecular testing combined with microscopic analysis, researchers found that while the fungus T. rubrum is most common, other molds and yeasts cause many infections too. Importantly, women and older adults are more likely to have infections from these other organisms, which are often harder to treat with standard antifungal medications.

Onychomycosis in the US Pediatric Population—An Emphasis on Fusarium Onychomycosis

mycolabadmin

This study examined nail fungus infections in American children using advanced molecular testing. Researchers found that elementary school-aged children (ages 6-11) have the highest rates of nail fungus, usually caused by common fungi like Trichophyton rubrum. Notably, Fusarium, an environmental fungus that was once rare in nail infections, is becoming increasingly common, especially in older teenagers, which may require different treatment approaches.

Emergence of resistant dermatophytosis caused by Trichophyton indotineae: First case series in Thailand

mycolabadmin

Researchers in Thailand identified five patients with a new type of fungal skin infection caused by Trichophyton indotineae, a species that resists the common antifungal drug terbinafine. These infections appeared as rashes on various parts of the body and required treatment with alternative medications like itraconazole. The findings represent the first confirmed cases in Thailand and suggest this resistant fungus may be spreading globally. The study also showed that a simple urease test could help doctors identify this resistant strain quickly without waiting for complex genetic testing.

Clinico-mycological study of superficial mycoses and correlation with anti-fungal susceptibility among the Candida isolates in a teaching institution of Western India

mycolabadmin

This study examined fungal skin infections in 330 patients in Western India, identifying which fungi cause these infections and which antifungal drugs work best. Researchers found that Candida yeasts were especially common in nail infections while Trichophyton fungi were more common in skin infections. The antifungal drug caspofungin was most effective against Candida, while the commonly used drug fluconazole showed increasing resistance.

Epidermophyton floccosum, an etiological agent of tinea pedis and tinea unguium: about two cases

mycolabadmin

Two elderly patients were diagnosed with fungal nail and foot infections caused by Epidermophyton floccosum, a fungus that has become less common in recent years. Both cases were confirmed using advanced molecular testing (real-time PCR) alongside traditional laboratory methods. The infections were successfully treated with terbinafine, an antifungal medication. This case report highlights the importance of using modern diagnostic techniques to accurately identify and treat fungal infections.

Safety and efficacy of the swift microwave device in patients with mild-to-moderate onychomycosis: Protocol of an open-label, randomized, dose-finding pilot study

mycolabadmin

This study evaluates a new microwave device (Swift System) as a potential treatment for fungal nail infections (onychomycosis). The device uses microwave energy to heat and eliminate fungal infections directly at the nail site, avoiding the side effects of oral medications. Researchers tested three different treatment schedules in 39 patients over 12 months to find the most effective dosing approach.

Emergence of resistant dermatophytosis caused by Trichophyton indotineae: First case series in Thailand

mycolabadmin

Researchers in Thailand have identified the first cases of a new resistant fungal skin infection caused by Trichophyton indotineae. This fungus is resistant to a commonly used antifungal drug called terbinafine and causes persistent skin rashes on various body parts. The study describes five patients whose infections were finally identified through genetic testing and who responded well to alternative antifungal treatment with itraconazole. This discovery suggests the fungus is now spreading in Thailand and doctors should watch for it.

Randomized control trial to study the effectiveness of tablet Fluconazole, capsule Itraconazole and tablet Terbinafine in superficial dermatophytosis

mycolabadmin

This study tested three common antifungal medications used to treat fungal skin infections like ringworm. The research involved 180 patients who were randomly given one of three drugs and then checked at 4 and 8 weeks to see if the infection was gone. Itraconazole worked best, clearing infections in about 87% of patients, followed by Fluconazole at 73%, and Terbinafine at 63%.
