A survey of dermatophytes isolated from patients seeking medical advice was made from 1985 to 1987 in the United States. The survey included 54 locations with data from 45 cities and one state. Listing of the isolated dermatophytes and the frequency given by percentage of the total follows: Trichophyton rubrum 54.8%, T. tonsurans 31.3%, T. mentagrophytes 6.0%, Microsporum canis 4.0%, Epidermophyton floccosum 2.0%, M. gypseum 0.6%, and T. verrucosum 0.2%. Out of a total of 14,696 isolates M. audouinii was cultured 13 times, T. violaceum 12 times, M. nanum 6 times, T. terrestre 4 times, and T. soudanense twice. Single isolations were made of M. fulvum, M. ferrugineum and T. schoenleinii. Collection of dermatophyte data in Tucson, Arizona, began in 1966. In 1987, the first case of tinea capitis caused by T. tonsurans was observed. Other isolates of this organism as the cause of tinea capitis were made in this city during that year. These infections were in black children. With the recent growth of Tucson, the percentage of blacks in the population increased and this pathogen was introduced into the general population.
1985年至1987年期间，在美国对因皮肤病就医的患者所分离出的皮肤癣菌进行了一项调查。该调查涵盖了54个地点，数据来自45个城市和一个州。所分离出的皮肤癣菌及其占总数的百分比频率如下：红色毛癣菌54.8%，断发毛癣菌31.3%，须癣毛癣菌6.0%，犬小孢子菌4.0%，絮状表皮癣菌2.0%，石膏样小孢子菌0.6%，疣状毛癣菌0.2%。在总共14696株分离菌株中，奥杜盎小孢子菌培养出13次，紫色毛癣菌12次，短柄帚霉6次，土生毛癣菌4次，苏丹毛癣菌2次。黄癣菌、铁锈色小孢子菌和许兰毛癣菌仅分离出1次。1966年开始在亚利桑那州图森市收集皮肤癣菌数据。1987年，观察到首例由断发毛癣菌引起的头癣病例。同年在该市还分离出该菌作为头癣病因的其他菌株。这些感染发生在黑人儿童中。随着图森市近期的发展，人口中黑人的比例增加，这种病原体传播到了普通人群中。
