Genomic Surveillance of Streptococcus pyogenes Strains Causing Invasive Disease, United States, 2016–2017

Abstract

While the overall population structure of invasive <i>S. pyogenes</i> isolates in the United States remained stable, some lineages, including several that were antibiotic-resistant, increased between 2016 and 2017. Continued genomic surveillance can help monitor and characterize bacterial features associated with emerging strains from invasive infections.
