Zoophilic dermatophytosis is a major public and veterinary health problem globally widespread among cattle. To identify the causative agent and geographical distribution of dermatophytes involved in cattle ringworm and to establish if they would be related to human diseases in Iran, a study was carried out on 6789 heads of cows and 130 herdsmen during 2006-2007. Samples were taken from 380 cattle and 43 herdsmen with suspected dermatophytosis. The causative agents were identified macroscopically and microscopically by KOH examination and culture isolation. Only 352 cases of dermatophytosis were identified in cattle and Trichophyton verrucosum was the exclusive fungus isolated from animals. Moreover, 27 cases of human dermatophytosis were identified and T. verrucosum was the prevalent causative agent for dermatophytosis in the body, scalp, foot, nail and groin of the patients. The obtained results showed that T. verrucosum was the predominant cause of dermatophytosis in livestock and dairy farmers. There is a scarcity of information on isolation and identification of the epizoonotic agents of dermatophytoses in cattle in Iran. This study showed the occurrence of dermatophytosis in humans and cattle and confirms that the dermatozoonoses are responsible for predominant forms of the disease in people who were in contact with cattle.
动物源性皮肤真菌病在全球范围内广泛存在于牛群中，是一个主要的公共卫生和兽医健康问题。为了确定参与牛环形癣的致病因子和地理分布，并确定它们是否与伊朗的人类疾病有关，在 2006 年至 2007 年期间，对 6789 头牛和 130 名牧民进行了一项研究。从 380 头牛和 43 名牧民中采集了疑似皮肤真菌病的样本。通过 KOH 检查和培养分离，在宏观和微观上确定了病原体。仅在牛中发现 352 例皮肤真菌病，从动物中分离出的唯一真菌是疣状毛癣菌。此外，还鉴定了 27 例人类皮肤真菌病，疣状毛癣菌是患者体癣、头癣、足癣、甲癣和腹股沟癣的主要致病因子。研究结果表明，疣状毛癣菌是家畜和奶牛场牧民皮肤真菌病的主要原因。关于伊朗家畜和野生动物皮肤真菌病的病原体的分离和鉴定，信息匮乏。本研究显示了人与牛中皮肤真菌病的发生，并证实了动物源性皮肤真菌病是与人接触牛的人患病的主要形式。
