260例浅部真菌病及致病菌种分析

目的了解新疆乌鲁木齐市浅部真菌病发病情况及其病原菌的菌种分布。方法对2004年2月至2010年08月在新疆医科大学第一附属医院皮肤科门诊就诊,临床拟诊为头癣、甲癣、体股癣、手足癣的1 308例患者取病发、皮屑、甲屑行真菌镜检、培养。培养阳性标本在形态学鉴定的基础上行核糖体DNA(rDNA)ITS区序列测定确切鉴定菌种。使用SPSS 17.0统计软件对于结果进行统计分析。结果真菌镜检培养均为阳性患者260例,头癣培养阳性率最高,占33.1%,其次为体股癣占28.8%、甲癣占21.5%、手足癣占16.5%;菌种鉴定:红色毛癣菌为最常见的致病菌(28.5%),其次为须癣毛癣菌(22.3%)、犬小孢子菌(18.8%)、断发毛癣菌(10.0%)。犬小孢子菌为头癣最主要致病菌(16.2%)。统计学分析显示:不同性别、族别间体股癣、手足癣发病率有统计学意义(P<0.05),均好发于男性,汉族发病率高于维吾尔族。不同年龄头癣、甲癣、体股癣、手足癣发病率差异也均有统计学意义(P<0.05),甲癣、体股癣、手足癣好发于中青年,头癣好发于儿童。结论乌鲁木齐市浅部真菌病主要致病真菌是红色毛癣菌。头癣是本地区最主要的儿童浅部真菌病,主要病原菌为犬小孢子菌。
