基于RPA-侧向流试纸条技术的单核细胞增生李斯特氏菌快检技术
Rapid Detection Technology for Listeria Monocytogenes Based on RPA-Lateral Flow Strip Technology
摘要
Abstract
In order to enable food production enterprises to conduct more efficient and convenient daily monitoring of foodborne pathogens in the production environment,this study developed a rapid detection technology for Listeria monocytogenes based on recombinase polymerase amplification(RPA)-lateral flow strip technology,and analyzed the specificity,sensitivity,and detection limit of the method.The sensitivity of the lateral flow strip detection was 6.5×102 CFU/mL after 15 min of RPA amplification.The detection limit was 1 CFU/mL after 8 hours of enrichment of artificially contaminat-ed samples.The rapid detection method for Listeria monocytogenes established in this study does not require the assistance of large experimental equipment,and can be completed within 20 minutes af-ter simple training for testing personnel,providing good technical support for enterprises to monitor Listeria monocytogenes in the production environment from the source,and also promoting the im-provement of food safety quality control levels in the entire industry.关键词
