Emergence of Sequence Type 398 as a Community- and Healthcare-Associated Methicillin-Susceptible Staphylococcus aureus in Northern Manhattan

Abstract

The methicillin-susceptible Staphylococcus aureus (MSSA) clone sequence type (ST) 398 has increasingly been identified as a pathogen in diverse geographic settings, yet its epidemiology remains incompletely understood. In this case-control study of MSSA infections, we identified ST398 MSSA as both a major community- and hospital-associated MSSA pathogen in the Dominican neighborhood of northern Manhattan.
