分子诊断技术在临床微生物学检验中的应用

摘要

Applications of molecular diagnostics in clinical microbiology laboratory were introduced in the article,including nucleic acid hybridization,nucleic acid amplification,DNA sequencing,gene chips and mass spectrometry.Molecular diagnostic techniques provide major tools for rapid diagnosis of infectious diseases,molecular epidemiology investigation,rapid identification of microbial pathogens and the study of the pathogenicity and antibiotics resistance.The application of these new technologies,as the complement of traditional culture methods,increases sensitivity,accuracy and diagnostic efficiency of assays.%主要介绍分子诊断技术在临床微生物学检验中的应用,内容包括核酸杂交、核酸扩增、DNA测序、基因芯片和质谱技术.分子诊断技术为感染病的快速诊断、分子流行病学调查、微生物的快速鉴定、病原菌的致病性和抗生素的耐受性研究等提供了重要的检测手段.这些新技术的应用,作为传统培养法的补充,提高了检测的灵敏度、准确性和诊断效率.
