目的了解黑龙江省大庆地区人工养殖银狐狸皮肤被毛携带真菌情况,为临床防治皮肤癣菌病在人与动物之间的传播提供流行病学资料。方法刮取狐狸饲养员病变处皮屑,毛刷法采集动物体表被毛,分别接种于沙堡弱培养基培养2周,对菌落进行形态及显微镜下结构鉴定。结果108只人工养殖银狐狸的皮肤癣菌的带菌率为27.78%(30/108),体表腐生菌以链格孢霉属、曲霉属和念珠菌属为主,另有41株真菌未定类。5名患皮肤癣菌病的银狐狸饲养员检出石膏样小孢子菌1株,须癣毛癣菌2株,犬小孢子菌1株,红色毛癣菌1株。结论黑龙江省大庆地区人工养殖的健康银狐狸被毛携带皮肤癣菌,并可能传染给人类而致皮肤癣菌病。
Objective To understand the situation of the fungus carried on the furred skin of silver fox in artificial breeding of Daqing area in Heilongjiang Province and to provide epidemiological data for the prevention and treatment of dermatophytosis in human and animal. Methods The barks of the fox keepers were scalded and the surface coat of the animals was collected by brush method. The hairs were inoculated into the weak medium of sandcastle for 2 weeks, respectively. The morphology and microstructure of the colonies were identified. Results The infection rate of dermatophytes of 108 farmed silver foxes was 27.78% (30/108). The surface saprophytic bacteria were mainly Alternaria, Aspergillus and Candida, and 41 were undetermined . Five silver fox breeders with dermatophyte disease detected 1 gypsum-like microsporum, 2 trichophyton mentagrophytes, 1 canine microsporum and 1 trichophyton rubrum. Conclusion The healthy silver fox breed artificially cultured in Daqing area of Heilongjiang Province may carry dermatophytes and may be transmitted to humans and cause dermatophytosis.
