Superficial mycoses caused by dermatophytes, as well as asymptomatic carriership of dermatophytes, have a high prevalence among domestic animals and pets. We examined 606 clinical specimens from skin lesions of animals with a significant tendency towards superficial mycosis due to their clinical features. Samples were obtained from horses, dogs, cats, small rodents, birds, and rabbits. The specimens were examined by microscopic and cultural techniques. Microscopically, there was no significant difference in the prevalence of structures which may develop fungal elements between the groups culturally positive or negative for dermatophytes and yeasts. Overall, 24.6% of the samples were microscopically positive. In specimens obtained from horses, a high contamination rate of 36%, mostly due to moulds, was found with a cycloheximide supplemented medium, making the examination of these cultures for the growth of dermatophytes impossible. The other animals showed a significantly lower contamination rate, 11% on average. In horses, Trichophyton equinum had the highest prevalence, in small rodents. Trichophyton mentagrophytes, and in cats Microsporum canis. Overall, 10% of the culturally examinable samples were positive for dermatophytal or yeast growth, though yeasts had only a very low isolation frequency.
由皮肤癣菌引起的浅表真菌病以及皮肤癣菌的无症状携带状态，在家畜和宠物中具有很高的患病率。我们检查了606份来自动物皮肤病变的临床标本，这些动物因其临床特征而有明显的浅表真菌病倾向。样本取自马、狗、猫、小型啮齿动物、鸟类和兔子。通过显微镜检查和培养技术对标本进行检查。在显微镜下，在皮肤癣菌和酵母菌培养阳性或阴性的组之间，可能形成真菌成分的结构的患病率没有显著差异。总体而言，24.6%的样本在显微镜下呈阳性。在用补充了放线菌酮的培养基培养时，从马身上获取的标本污染率很高，达36%，主要是霉菌污染，这使得无法对这些培养物进行皮肤癣菌生长的检查。其他动物的污染率明显较低，平均为11%。在马中，马毛癣菌的患病率最高，在小型啮齿动物中，须癣毛癣菌患病率最高，在猫中，犬小孢子菌患病率最高。总体而言，在可进行培养检查的样本中，10%的样本皮肤癣菌或酵母菌生长呈阳性，不过酵母菌的分离频率非常低。
