Control of infection caused by Microsporum canis in pet animals are important for prevention of zoonosis. Treatments for animal dermatophytosis have generally consisted of itraconazole (ITZ) and terbinafine (TRF); however, a TRF-resistant M. canis strain from a case of feline dermatophytosis has been reported. In the present study, we examined the in vitro susceptibility of clinical isolates of M. canis to new antifungal drugs, such as ravuconazole (RVZ) and luliconazole (LCZ). The results indicated that RVZ and LCZ are more effective than ITZ and TRF. Therefore, oral administration of RVZ or topical application of LCZ may serve as new treatment options.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

Epidemiological studies combining taxonomic and clinical data have been limited globally, particularly Guiyang, the most under-developed economic provincial capital city in southwestern China. A retrospective analysis was performed of dermatophyte epidemiology involving all culture-positive cases received between May 2017 and May 2023 at the Affiliated Hospital of Guizhou Medical University. Phylogenetic analysis was conducted on 391 dermatophyte isolates collected from patients using the rDNA internal transcribed spacer sequences.

Background: Few ex vivo studies have investigated the virulence factors of fungi causing onychomycosis. The effect of nail polish in predisposing or protecting against onychomycosis remains debatable.
Objectives: This ex vivo study aimed to identify the nail invasion ability of dermatophytes, non-dermatophytes and yeast, with and without nail polishing, in the nails of young and elderly individuals.

Background And Purposes: The fungi known as dermatophytes are a group of keratinophilic agents responsible for superficial infections in humans and animals. Recognition of the species distribution and epidemiology of dermatophytosis may be helpful in the prevention and improve prophylactic measures. The present molecular epidemiology study sought to investigate the incidence of etiological agents causing dermatophytosis.
