Abstract：
BACKGROUND: Dermatophytosis (ringworm) caused by members of the Trichophyton mentagrophytes complex is rarely diagnosed in pigs but has been recognized as an increasingly common infection in humans. Further, resistance to antifungal drugs have been reported both in Asia and in Europe. This is the first scientific report of infection by the T. mentagrophytes complex in pigs in the Nordic countries.
METHODS: Skin lesions developed in grower pigs in an organic fattening pig farm with outdoor production and following laboratory analyses, dermatophytosis caused by members of the T. mentagrophytes complex was diagnosed. Infection was linked to poor hygiene, high humidity, and moderate outdoor temperatures, in combination with high pig density. A farm worker developed a skin lesion after close contact with affected pigs, which highlighted the zoonotic potential of porcine dermatophytosis. The dermatophytes may have originated from the herd supplying the growers where similar lesions occurred in pigs. Further, pigs from another organic fattening herd that received growers from the same supplier herd also developed dermatophytosis. The lesions healed without treatment as the housing conditions were improved. Isolation of affected pigs prevented spread to other pigs CONCLUSION: Members of the T. mentagrophytes complex can cause ringworm in pigs. The fungi probably persist in the haircoat and may cause overt disease when environmental conditions promote growth of mycelia.

摘要：
背景：在猪中很少诊断出由毛癣菌的成员引起的皮肤癣菌病（癣），但已被认为是人类越来越常见的感染。Further,在亚洲和欧洲都有抗真菌药物耐药性的报道。这是北欧国家的猪中的T.mentagrosphytes复合体感染的第一份科学报告。
方法：在户外生产的有机育肥猪场中，生长猪出现皮肤损伤，并进行实验室分析，诊断为由T.mentagrosphytes复合体成员引起的皮肤癣菌病。感染与不良的卫生状况有关，高湿度,室外温度适中，与高密度猪相结合。一名农场工人在与受影响的猪密切接触后出现皮肤损伤,这突出了猪皮肤癣菌病的人畜共患潜力。皮肤癣菌可能起源于为猪中发生类似病变的种植者提供的牛群。Further,来自另一个有机育肥牛群的猪也出现了皮肤癣菌病。随着住房条件的改善，病变无需治疗即可治愈。隔离受影响的猪可以防止传播到其他猪。当环境条件促进菌丝体生长时，真菌可能会持续存在于头发中，并可能引起明显的疾病。
