宜昌地区浅部真菌病及真菌分析

Prevalence of pathogenic fungi of superficial mycoses in Yichang

目的了解宜昌地区浅部真菌病及真菌分布特点。方法对在医院皮肤科就诊,并拟诊为浅部真菌病感染的1982例患者标本,行显微镜检查、细菌培养及菌种鉴定。结果 1982例浅部真菌病患者中,甲真菌病691例,占34.9%,股癣402例,占20.3%,足癣374例,占18.9%;分离的1030株真菌中,主要为红色毛癣菌626株,占60.8%;其余依次为假丝酵母菌属、须癣毛癣菌、絮状表皮癣菌及犬小孢子菌,分别占22.2%、5.5%、2.8%、2.4%。结论在浅部真菌病及病原菌中,甲真菌病最为常见,致病菌以红色毛癣菌占主导地位,假丝酵母菌属所占比例较往年有大幅增多。

OBJECTIVE To investigate the prevalence and pathogenic fungi species of superficial mycoses in Yichang district.METHODS A total of 1982 specimens of clinically suspected patients in dermatological department with dermatomycoses were examined by Microscopy.The bacterial culture and identification were performed.RESULTS Among 1982 cases,the frequencies of onychomycosis（691 cases）,tinea cruris（402 cases） and tinea pedis（374 cases） were 34.9%,20.3% and 18.9%,respectively.1030 strains of pathogenic fungi were isolated,in which the most frequently isolated fungus was Trichophyton rubrum 626（60.8%）,followed by Trichophyton mentagrophytes（5.5%）,Epidermophyton floccosum（2.8%）,candida and yeast-like fungi（22.2%）and others（2.4%）.CONCLUSION Onychomycosis is the most common,and Trichophyton rubrum is the most predominant pathogen of dermatomycoses.The percentage of candida and yeast-like fungus is increased year by year.
