下呼吸道感染真菌的分离鉴定及药敏分析

目的了解下呼吸道真菌感染情况及对抗真菌药物抑菌效果,为临床提供帮助。方法对医院2006年1月-2008年12月临床送检的痰液或纤维支气管镜收集的标本,按照全国临床检验操作规程的有关要求进行分离鉴定,对其中较常见的假丝酵母菌属(106株),采用Rosco纸片扩散法对常用5种抗真菌药物进行药敏试验。结果 2116份痰标本共分离出6种假丝酵母菌属,共422株,检出率19.9%,其中以白色假丝酵母菌为主,占52.1%,其次是热带假丝酵母菌,为20.4%,类星形假丝酵母菌、克柔假丝酵母菌、近平滑假丝酵母菌、高里假丝酵母菌、皱褶假丝酵母菌,分别为12.1%、6.2%、5.0%、2.8%、1.4%;大多为与细菌混合感染;药敏结果为白色假丝酵母菌和类星形假丝酵母菌敏感率大多>90.0%,热带假丝酵母菌敏感率也>80.0%,克柔假丝酵母菌对氟康唑几乎全部耐药。结论下呼吸道假丝酵母菌感染比较严重,且常与细菌合并感染;常见感染假丝酵母菌对常用抗真菌药物有一定耐药性,应引起重视;Rosco纸扩散法操作简单,结果可靠稳定,适用常规抗真菌药敏试验。
