High-depth whole genome sequencing of blood culture plates reveals evolutionary dynamics in cases of persistent bacteremia due to methicillin-resistant <i>Staphylococcus aureus</i>
bacteremia. Overall, these data provide a detailed view of evolutionary dynamics during clinical cases of MRSA bacteremia and describe the merits and limitations of a c-seq versus p-seq strategy for analyzing blood culture plates using WGS. Importance: by applying WGS to either each of five individual colonies isolated on blood culture plates (c5-seq) or the pooled bacterial population on each plate (p-seq). We found that c5-seq was a more practical and informative method to understand evolutionary dynamics.
