马尔堡病毒双重实时荧光定量PCR检测方法的建立
Establishment of a dual real-time fluorescence quantitative PCR method for detection of marburg virus
摘要
Abstract
This study developed a dual-fluorescence RT-PCR method for rapid detection of marburg virus(MARV),a filovirus that causes hemorrhagic fever.Five primer and probe sets were designed to target variable regions of the MNP and MGP genes.The as-say was optimized,and its performance was validated with national reference materials for MARV nucleic acid detection.For valida-tion,we assessed the compliance rates of positive and negative controls,the method's precision,and its limit of detection.Evaluation of 19 national reference samples confirmed the method's high accuracy,and 100%compliance for both positive and negative controls.All 6 positive controls exhibited consistent amplification in the FAM and VIC channels,corresponding to MNP and MGP,and all seven negative controls yielded negative results.The assay demonstrated a low detection limit below 1.4×10⁴ copies/mL for the MNP gene and 2.0×10⁴ copies/mL for the MGP gene.Precision testing indicated excellent reproducibility,with coefficients of variation be-low 5%for all channels.These findings indicated that the dual-fluorescence RT-PCR method is specific,sensitive,and reproducible,thus meeting national reference criteria.The assay is therefore suitable for deployment in grassroots disease control and healthcare set-tings for effective MARV surveillance and outbreak early warning.关键词
