Pet dogs have been considered to be involved in the contamination of indoor air by serving as a source of providing molds at houses. Currently, information on the molds originated from pet dogs is rarely available in Korea. The present study was carried out to obtain basic information on the fungi present on pet dogs. For this, fungal isolation was performed to the skin and hairs of 70 pet dogs at different houses and veterinary hospitals. A total of 44 fungal isolates were obtained from skin (27 isolates) and hairs (17 isolates) of the dogs investigated. Based on the observation of microstructures and colony morphology, and the ITS rDNA sequence analysis, the fungal isolates were identified at the level of genus. The identified isolates belong to the genera of Alternaria, Aspergillus, Beauveria, Chrysosporium, Cladosporium, Penicillium, Scopulariopsis, and Trichoderma. Among these genera, Aspergillus (25%), Cladosporium (23%) and Penicillium (20.5%) were 3 major genera. 63% of the 44 isolates showed color changes on dermatophyte test medium (DTM). When we tested the growth ability of 44 isolates at 37℃, 45% of the isolates were able to grow. These results show that pet dogs could carry fungi having a potentiality of affecting on human health.
宠物狗被认为是室内空气污染的一个源头，因为它们会在室内滋生霉菌。目前，在韩国，关于源自宠物狗的霉菌的信息很少。本研究旨在获取有关宠物狗身上存在的真菌的基本信息。为此，对来自不同家庭和兽医医院的70只宠物狗的皮肤和毛发进行了真菌分离。从所调查的狗的皮肤（27株分离株）和毛发（17株分离株）中总共获得了44株真菌分离株。基于微观结构和菌落形态的观察以及ITS rDNA序列分析，这些真菌分离株被鉴定到属水平。鉴定出的分离株属于链格孢属、曲霉属、白僵菌属、金孢子菌属、枝孢属、青霉属、拟青霉属和木霉属。在这些属中，曲霉属（25%）、枝孢属（23%）和青霉属（20.5%）是三个主要的属。44株分离株中有63%在皮肤癣菌测试培养基（DTM）上出现颜色变化。当我们测试44株分离株在37℃下的生长能力时，45%的分离株能够生长。这些结果表明，宠物狗可能携带对人类健康有潜在影响的真菌。
