Routine medical microbiology diagnostics relies on conventional cultivation followed by phenotypic techniques for identification of pathogenic bacteria and fungi. This is not only due to tradition and economy but also because it provides pure culture needed for antibiotic susceptibility testing. This review focuses on the potential of High Resolution Melting Analysis (HRMA) of double-stranded DNA for future routine medical microbiology.
Search of MEDLINE database for publications showing the advantages of HRMA in routine medical microbiology for identification, strain typing and further characterization of pathogenic bacteria and fungi in particular. The results show increasing numbers of newly-developed and more tailor-made assays in this field. For microbiologists unfamiliar with technical aspects of HRMA, we also provide insight into the technique from the perspective of microbial characterization.
We can anticipate that the routine availability of HRMA in medical microbiology laboratories will provide a strong stimulus to this field. This is already envisioned by the growing number of medical microbiology applications published recently. The speed, power, convenience and cost effectiveness of this technology virtually predestine that it will advance genetic characterization of microbes and streamline, facilitate and enrich diagnostics in routine medical microbiology without interfering with the proven advantages of conventional cultivation.
常规医学微生物诊断依赖于传统培养方法,随后采用表型技术来鉴定病原菌和真菌。这不仅是出于传统和经济原因,还因为它能提供抗生素敏感性测试所需的纯培养物。本综述聚焦于双链DNA的高分辨率熔解分析(HRMA)在未来常规医学微生物学中的潜力。
检索MEDLINE数据库,查找展示HRMA在常规医学微生物学中用于病原菌和真菌鉴定、菌株分型及进一步特征分析优势的文献。结果表明该领域新开发且更具针对性的检测方法数量不断增加。对于不熟悉HRMA技术方面的微生物学家,我们也从微生物特征分析的角度对该技术进行了介绍。
我们预计医学微生物学实验室中HRMA的常规应用将为该领域提供强大的推动力。近期发表的越来越多的医学微生物学应用已体现了这一点。该技术的速度、效能、便利性和成本效益实际上注定它将推动微生物的基因特征分析,并在不干扰传统培养法已证实优势的情况下,简化、促进和丰富常规医学微生物诊断。
