临床常见真菌的分布和药物敏感性分析

目的:了解真菌感染的临床分布、真菌种类及耐药情况,为临床诊治提供依据。方法:采用沙保弱平板或CHROMa-gar平板进行菌株分离、API Candida、API20CAUX菌株鉴定,用Rosco纸片扩散法测定药敏。结果:690份标本,分离出700株真菌,其中假丝酵母菌属占53.5%,白假丝酵母菌占25.6%;痰标本占24.3%;住院患者中以ICU和肾内科分离率高且以白假丝酵母菌为主,分别占59.3%和45.2%;门诊患者以皮肤科分离率高,以近平滑假丝酵母菌为主,占23.4%;酵母样真菌对伊曲康唑、氟康唑、两性霉素B、制霉菌素、酮康唑的敏感率分别为89.4%、83.9%、98.2%、95.9%、96.0%。结论:假丝酵母菌是真菌培养中分离率最高的真菌,分离的主要真菌种类因科室和患者而异。真菌的分离、鉴定和药敏试验对临床使用抗真菌药物具有指导意义,特别是对氟康唑天然耐药菌株的鉴定,有利于抗真菌药物选择。

Analysis of antifungal susceptibility in vitro and fungi distribution in clinics

Objective:To analyze the antifungal susceptibility and fungi distribution in clinical.Methods: Sabouraud agar and CHROMagar were used to culture fungi.Identifications of fungi strains were detected by API Candida and API20C AUX.Antifungal susceptibility was determined by Rosco disc agar diffusion method.Results: Candida was 53.5%,of which C.albicans was 25.6% in total of 700 clinical isolates;C.albicans were mainly isolated from ICU and Dept.of nephrology with 59.3% and 45.2% respectively;C.parapsilosis was...
