<p>Comprehensive strain-level tracking analysis of oral bacteria using inStrain.</p>

Summary of inStrain strain tracking output showing bacterial strain sharing patterns across multiple comparison types: (1) within-individual sample-to-sample sharing (tongue vs. plaque), (2) within-individual temporal stability (1-month and 6-month time points), and (3) vertical transmission between mothers and infants at 1 month and 6 months postpartum. Results indicate whether identical bacterial strains were detected between sample pairs. (XLSX)
