During a study of the epidemiology of Microsporum canis and closely related species, sub-specific variation was demonstrated within thirteen isolates of Microsporum distortum based on the pattern of carbohydrate utilization. Strains from three continents could be differentiated by their utilization of trehalose and erythritol. Isolates from New Zealand yielded the same patterns as M. canis (Arthroderma otae (-)); examination of 120 isolates indicated that M. canis could not be biotyped by carbohydrate utilization, although limited variation had been noted. Examination of total native protein patterns by gel electrophoresis showed that variations existed within the M. distortum group; the much larger number of M. canis (A. otae (-)) strains had appeared to be homogenous.
在一项关于犬小孢子菌及密切相关菌种的流行病学研究中，基于碳水化合物利用模式，在13株扭曲小孢子菌分离株中证实了亚种内变异。来自三大洲的菌株可通过对海藻糖和赤藓糖醇的利用情况加以区分。来自新西兰的分离株呈现出与犬小孢子菌（耳状节皮菌（-））相同的模式；对120株分离株的检测表明，尽管已注意到有限的变异，但犬小孢子菌无法通过碳水化合物利用进行生物分型。通过凝胶电泳对总天然蛋白质模式的检测显示，扭曲小孢子菌群内存在变异；而数量多得多的犬小孢子菌（耳状节皮菌（-））菌株似乎是同质的。
