Dermatofitose canina causada pelo fungo antropofílico Trichophyton tonsurans - Relato de caso

Abstract

Dermatophytoses is a skin disease caused by fungi that deserves attention for its high incidence in clinical small animal and animal and human health importance because it can be transmitted from animals to humans or from humans to animal. This study aimed to report a case of canine dermatophytoses caused by anthropophilic species of dermatophyte, involving clinical and laboratory diagnosis. A dog, female, York Shire, with about three years of age, revealed generalized alopecia and therefore was referred for a consultation, in which the clinical suspicion was dermatophytoses. Skin scales and hair for laboratory tests were collected. On direct examination, there was no evidence the presence of fungal structures. However, fungal culture of the clinical specimen showed the growth of colonies of Trichophyton tonsurans. The therapy with itraconazole, an antifungal broad spectrum, was effective. This case report emphasizes the need to conduct laboratory exams in the presence of suspicious lesions of dermatophytoses for identification of the etiologic agent and subsequently adoption of control and prevention measures of this disease, which presents a complex epidemiological chain of transmission.
