Molecular and epidemiological characteristics of iGAS isolates in Argentina. Molecular Epidemiology of Invasive Group A Streptococcus Infections in Argentina during 2023

Amidst Argentina's 2023 surge in invasive Streptococcus pyogenes infections, nationwide genomic analysis uncovered prevalent M1 strains and emergent M1-UK and M1-DK sublineages. This seminal study provides initial insights into the iGAS genomic landscape, contributing for active surveillance to monitor virulent cross-border transmission in South America
