This study was made possible through an amazing collaboration across the CHOP NICU, CHOP Infectious Disease Diagnostics Lab (IDDL), CHOP Infection Prevention and Control, the Microbial Archive and Cryocollection at CHOP (MicrobialARC), and @centermicrobialmed.bsky.social.

In this study we tracked carriage, transmission, and invasive infection with S. aureus across 33 months in the NICU. Using longitudinal WGS, we identify risk factors for transmission of invasive clones, and show strains that are transmitted more rapidly are more likely to cause invasive disease
