RESUMO
Seventy cattle suspected to dermatophytosis were examined between March and April 2003. The samples were taken from different lesions by scraping method. Direct microscopic examination and culture were carried out. The mean of infection duration was 2 weeks. Forty-three cases were appeared with positive clinical signs of dermatophytosis and 27 cases were asymptomatic. The etiologic agent of the infection was only Trichophyton verrucosum. A significant relation was observed between the frequency of head and neck lesions and other sites. There was a significant difference between the frequency of head lesions and other sites. Since human dermatophyte infections due to Trichophyton verrucosum have been reported repeatedly in Iran, it is necessary to design a preventive program such as developing an effective vaccine against dermatophytosis into the future
