Full Sequencing and Genomic Analysis of Three emm75 Group A Streptococcus Strains Recovered in the Course of an Epidemiological Shift in French Brittany.

While the incidence and invasiveness of type emm75 group A Streptococcus (GAS) infections increased in French Brittany during 2013, we sequenced and analyzed the genomes of three independent strains isolated in 2009, 2012, and 2014, respectively. In this short-term evolution, genomic analysis evidenced mainly the integration of new phages encoding virulence factors.
