摘要 目的:探讨肺炎支原体(MP)咽拭子快速液体培养法和血清MP-Ab法(IgG、IgM)等方法在儿童MP感染诊断中的敏感性。方法:采用3种MP检测法对231例临床拟诊为呼吸道(非细菌性)感染患儿的咽拭子和血清标本进行配对研究,每个患儿取咽拭子做快速培养,同时取血清做MP-Ab检测(IgG、IgM),对3种方法的检测结果与临床诊断治疗病例进行回顾性分析。结果:确诊MP感染患儿88例,MP快速培养法检出阳性49例,阳性率为21.21%,病程为(4.0±2.5)d;IgG检测出阳性31例,阳性率为13.41%,病程为(8.0±3.5)d;IgM检测出阳性28例,阳性率12.12%,病程(5.5±2.0)d。结论:咽拭子快速液体培养法具有较高的准确性,3种MP检测法的敏感性与病程有相关性,临床医生应根据患儿病程选取检测方法,以提高阳性检出率和敏感性。
