The ability of 17 strains of Epidermophyton to perforate hair in vitro using the Ajello & Georg's test procedure and a modification of Lu's method has been studied. Following the Ajello & Georg's test procedure only E. stockdaleae perforated hair. Sporadically some strains of E. floccosum perforated horse hair. We noted as well unusual perforations originated from inside to outside of the hair. By the other technique, all strains, excepting E. floccosum var. nigricans in child hair, perforated hair. E. floccosum showed these perforations later than E. stockdaleae.
运用阿杰洛（Ajello）和格奥尔格（Georg）的测试方法以及对卢氏方法的改良，研究了17株表皮癣菌在体外使毛发穿孔的能力。按照阿杰洛和格奥尔格的测试方法，只有斯氏表皮癣菌（E. stockdaleae）能使毛发穿孔。偶尔有絮状表皮癣菌（E. floccosum）的一些菌株能使马毛穿孔。我们还注意到毛发出现了从内向外的异常穿孔。通过另一种技术，除儿童毛发中的黑色絮状表皮癣菌变种（E. floccosum var. nigricans）外，所有菌株都能使毛发穿孔。絮状表皮癣菌出现这些穿孔的时间比斯氏表皮癣菌晚。
