摘　　要：目的:通过对浅部真菌感染患者的临床送检标本进行病原真菌菌种的分析,了解感染及病原真菌的分布情况。方法:采用直接镜检法、培养等方法对临床送检的标本进行检验和鉴定。结果:临床送检的标本中,直接涂片镜检阳性率为51.42%,培养阳性率为61.44%。在培养的标本中分离出14种菌种,分离得到的所有菌株中,红色毛癣菌71株(36.22%)、须癣毛癣菌46株(23.47%)及白念珠菌26株(13.27%)分占前3位。结论:皮肤癣菌是引起浅部真菌感染的主要原因,须癣毛癣菌与白念珠菌也是重要的病原菌。直接镜检的阳性率低于培养阳性率,可以考虑将二者结合,提高真菌的检出率,不轻易排除浅部真菌感染的可能性。Objective：To investigate the etiological characteristics of fungal pathogens in patients with superficial mycoses. Methotis： All clinical specimens were examined directly under microscopy, and by culture （inoculated upon Sabouraund, s glucose agar or other special medium）. All isolated strains were identified by their characteristic micromorphology and morphologic forms of colonies. Results： To investigate the clinical specimens. Clinical specimens received microscopy and culture gave the positive results as 51.42% and 61.44%. Approximately 14 fungi strains were isolated from clinical specimens. Trichophyton rubrum ,T. mentagrophytes and Candida albicans among these group isolated strains were 36. 22% .23.47% and 13. 27% ,to occupy the fore -three position. Conclusion： In light of the data, our findings indicated that dermatophytes were the main etiological fungi to get surperficial infeoction, T. mentagro-phytes and Candida albicans were still the important reasons to get superficial mycoses. Tire rates got from directly under microscopy were lower than cultare. Microscopy examination combinated with culture has a higher sensitivity,so this new way could avoid the possibility of infecting superficial mycoses.
