The performance and convenience of a PCR melting profile (PCR MP) technique based on using low denaturation temperatures during ligation mediated PCR (LM PCR) of bacterial DNA is shown. We found that PCR MP technique is a rapid method that offers good discriminatory power, excellent reproducibility and may be applied for epidemiological studies. Results from strain genotyping illustrate that PCR MP is useful for the study of intraspecific genetic relatedness of strains and is as effective in discriminating closely related strains as the PFGE method, which is currently considered to be the gold standard for epidemiological studies. The usefulness of the PCR MP for molecular typing was shown for clinical strains of Escherichia coli, Enterococcus faecium VRE and Stapylococcus aureus.
展示了一种基于在细菌DNA的连接介导PCR(LM PCR)过程中使用低变性温度的PCR熔解曲线(PCR MP)技术的性能和便利性。我们发现PCR MP技术是一种快速方法,具有良好的鉴别能力、出色的可重复性,可应用于流行病学研究。菌株基因分型结果表明,PCR MP可用于研究菌株的种内遗传相关性,在鉴别密切相关菌株方面与PFGE方法一样有效,而PFGE方法目前被认为是流行病学研究的金标准。PCR MP在分子分型方面的实用性已在大肠杆菌、粪肠球菌VRE和金黄色葡萄球菌的临床菌株中得到证实。
