Bacterial genotyping through whole-genome sequencing plays a crucial role in disease surveillance and outbreak investigations in public health laboratories. This study assessed the effectiveness of Oxford Nanopore Technologies (ONT) sequencing in the genotyping of and serovar Enteritidis. Our results indicated that ONT sequences, generated with the R10.4.1 flow cell and basecalled using the Dorado 0.5.0 Super Accurate 4.3 model, exhibited comparable accuracy to Illumina sequences, effectively discriminating among bacterial strains from outbreaks. These findings suggest that ONT sequencing has the potential to be a promising tool for rapid whole-genome sequencing of bacterial pathogens in public health laboratories for epidemiological investigations.
This study unveils that Oxford Nanopore Technologies sequencing, by itself, holds the potential to serve as a whole-genome sequencing-based genotyping tool in public health laboratories, enabling routine subtyping of bacterial isolates for disease surveillance and outbreak investigations.
全基因组测序在公共卫生实验室的疾病监测和疫情调查中起着至关重要的作用。本研究评估了牛津纳米孔技术(ONT)测序在 和 肠炎沙门氏菌血清型基因分型中的有效性。我们的结果表明,ONT 序列,使用 R10.4.1 流动池生成,并使用 Dorado 0.5.0 Super Accurate 4.3 模型进行碱基调用,其准确性可与 Illumina 序列相媲美,有效地区分了疫情中的细菌菌株。这些发现表明,ONT 测序有可能成为公共卫生实验室中用于流行病学调查的快速全基因组测序细菌病原体的有前途的工具。
本研究揭示了牛津纳米孔技术测序本身有可能成为公共卫生实验室中基于全基因组测序的基因分型工具,使常规对细菌分离物进行亚型分型,以进行疾病监测和疫情调查。
