Microsporum canis is the most common cause of feline dermatophytosis and the most pathogenic fungus isolated from the skin and hair of healthy cats. Cats are considered to be the natural reservoir and infection sourse of this disease in human and domestic animals.
Knowing the M. canis frequency in the dermatological healthy cat population of Temuco city, Chile.
Fifty cat samples were collected irrespective sex or race. Cats' ages were between 2 months and 12 years old, and the animals were treated at the Veterinary Clinical Hospital of the Universidad Católica de Temuco, or in three private clinics from this city. Tissue and hair samples were collected using two sampling techniques: hair extracting tweezers and the Mariat & Tapia method. For the clinical diagnosis, the Wood's lamp was used. Hairs were microscopically observed followed by a culture using Sabouraud agar and Lactrimel agar. M.canis was isolated in 30 cats (60%).
There were no statistically significative differences when parameters such as age, sex and race were taking into account. Differences between the use of Sabouraud agar and Lactrimel agar were not registered. It was determined that the Mariat & Tapia method was able to detect more dermatophytes than the collecting tweezers method. These differences were statistically significative.
The percentage of M. canis isolation obtained in this work remarks the role of healthy cats in the transmission of these dermatophytes to humans and other animals.
犬小孢子菌是猫皮肤癣菌病最常见的病因，也是从健康猫的皮肤和毛发中分离出的最具致病性的真菌。猫被认为是人类和家畜中这种疾病的天然宿主和感染源。
了解智利特木科市皮肤健康猫群中犬小孢子菌的感染率。
收集了50份猫的样本，不分性别或品种。猫的年龄在2个月至12岁之间，这些动物在特木科天主教大学兽医临床医院或该市的三家私人诊所接受治疗。使用两种采样技术收集组织和毛发样本：拔毛镊子和玛丽亚&塔皮亚法。临床诊断使用伍德灯。对毛发进行显微镜观察，然后使用沙氏琼脂和乳酸米诺环素琼脂进行培养。在30只猫（60%）中分离出犬小孢子菌。
在考虑年龄、性别和品种等参数时，没有统计学上的显著差异。未记录使用沙氏琼脂和乳酸米诺环素琼脂之间的差异。确定玛丽亚&塔皮亚法比拔毛镊子法能检测到更多的皮肤癣菌。这些差异具有统计学意义。
本研究中犬小孢子菌的分离率表明健康猫在将这些皮肤癣菌传播给人类和其他动物方面所起的作用。
