Whole-genome sequencing of Aerococcus christensenii isolates from pregnant women with bacteremia
The pure bacterial colonies were selected for genomic DNA extraction using the Rapid Bacterial Genomic DNA Isolation Kit (Sangon, China). Amplification was performed with the T100 Thermal Cycler PCR system (Bio-Rad, USA) and the accompanying reagents. Subsequently, a genomic library preparation was carried out using the NEBNext dsDNA Fragmentase and the NEBNext Ultra II DNA Library Prep Kit for Illumina (New England Biolabs, USA).
