Validating Metagenomic Analyses Through Simulated Direct and Indirect Healthcare-Related Pathogen Transmission Events

Abstract: The prevalence of healthcare-acquired infections (HAI) places a significant economic burden on modern healthcare systems. Cultures are typically used to diagnose HAI; however, culture-dependent methods provide only limited presence/absence information and are not applicable to all pathogens. Next generation sequencing (NGS) has the potential to detect a wide variety... MORE
