摘要: 目的 了解短波紫外线对几种常见浅部真菌生长的影响。方法 将红色毛癣菌、须癣毛癣菌、犬小孢子菌、絮状表皮癣菌、白念珠菌、光滑念珠菌、近平滑念珠菌、热带念珠菌、克柔念珠菌、青霉、短帚霉、枝顶孢霉接种在沙氏培养基上,按不同照射功率、不同照射距离和不同照射时间分组用紫外线灯进行照射,观察记录照射后菌落的生长情况,并在透射电镜下观察菌丝或孢子的形态结构变化。结果 犬小孢子菌、絮状表皮癣菌、白念珠菌、近平滑念珠菌、克柔念珠菌经照射后停止生长;红色毛癣菌、须癣毛癣菌、光滑念珠菌、热带念珠菌、短帚霉和枝顶孢霉在某些照射条件下可以继续生长,但生长速度减缓。结论 短波紫外线对常见浅部真菌有不同程度的杀灭和抑制作用,该作用的大小与紫外线照射强度和照射时间成正比,与照射距离成反比。

Abstract: Objective To investigate the effect to growth of superficial fungi by exposure to germicidal UV light.Methods Laboratorial fungi consisted of Trichophyton rubrum,T.mentagrophytes,M.canis Bodin,E.floccosum,C.albicans,C.glabrata,C.parapsilosis,C.tropicalis,C.krusei,Penicillium spp.,Scopulariopsis spp.,Acremonium spp. were inoculated on SDA that were exposed to UV light. All the tested fungi were divided into groups by exposure power, exposure distance and exposure time and morphological variations of hyphae and spores were observed with transmission electron microscope.Results M.canis Bodin,E.floccosum,C.albicans,C.parapsilosis,C.krusei stoped growing under exposure to germicidal UV light while others managed to be alive.Conclusions Germicidal UV light has different disinfection to some common superficial fungi, the degree of the disinfection depended on exposure power, distance and time.

Key words: superficial fungi, UV light, transmission electron microscope
