Dermatophytosis is a zoonotic disease caused by fungi of species dermatophyte. The case of dermatophytosis have increased not only in humans but also in animals, especially dogs and cats. The close interaction of cats and humans reported to play an important role in dissemination of zoonotic diseases. Therefore, this study aims to diagnose and to treat of dermatophytosis in cats. Twenty cats with the age of 6-12 months were used in this study. Determination of dermatophyte infection in cats based on clinical signs and laboratory identification of fungi. Skin scrapes samples were cultured onto Sabouraud's dextrose agar medium. Hair and skin scraping were conducted at the day-1 (pretreated with ketoconazole). Subsequently, infected cats were treated with topical application of 2% ketoconazole cream, twice a day for 21 days. Results showed that all of cats positive infected with Microsporum canis. Feature of the skin of cats infected by Microsporum canis demonstrates erythema, scale, crust, and circular alopecia. At day-21, antifungal treatment not only diminished by approximately 85% of the clinical feature of the skin lesion of cat's dermatophytosis but also resulted in the disappearance of the fungi. To conclude, topically applied of antifungal ketoconazole for at least three weeks effective to treat dermatophytosis in cats.
Fungal infection by dermatophytosis is a zoonotic disease distributed globally and well concern in public health. This study aimed to investigate clinical signs and the etiological agents of dermatophytosis in cats in Yogyakarta. A total of 69 cats were observed in this study. Physical examination, by using Wood's lamp, and microscopic examination of hyphae on the skin was used for preliminary screening of dermatophytosis. Identification of fungi was conducted by scrapping area infection of the skin and then cultured on Dermatophyte Test Medium (DTM) for macroscopic and microscopic examination. The results of this study demonstrated that dermatophytosis in cats is characterized by the presence of multifocal alopecia, scale, pruritus, and erythema on the skin with a specific formation. The dominant clinical lesion was alopecia followed by crust and erythema, stated at 75.8%, 42.8%, and 1.86% respectively. Physical examination showed that 55 cats (79.7%) were positive fungal infections by using direct Wood's lamp examination and skin scrappings. Moreover, the identification of agents demonstrated that 58 (84%) and 11 (16%) of cats were infected by M. canis and T. mentagrophytes, respectively. Besides clinical signs, Wood's lamp, and microscopic examination, the gold standard for M. canis idenification is Dermatophyte Test Medium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
