Streptococcus anginosus is considered an emerging opportunistic pathogen causing life-threatening infections, including abscesses and empyema. Noticeably, clinical data revealed that S. anginosus also constitutes an important component of polymicrobial infections.

Methods: The genomes of 136 M77 GAS isolates were sequenced using Illumina, and selected with long-read approach (Oxford Nanopore). Whole genome sequences were analyzed to determine the presence of macrolide resistance determinants, and their genetic context.
Streptococcus pyogenes (group A Streptococcus, GAS) is a major human pathogen and causes every year over 600 millions upper respiratory tract onfections worldwide. Untreated or repeated infections may lead to post-infectional sequelae such as rheumatic heart disease, a major cause of GAS-mediated mortality. There is no comprehensive, longitudinal analysis of the M type distribution of upper respiratory tract strains isolated in Poland.

However, recent epidemiological and clinical data designate this bacterium as an emerging opportunistic pathogen. Despite the reported pathogenicity of S.
