Capsular Switching and Other Large-Scale Recombination Events in Invasive Sequence Type 1 Group B Streptococcus

We report several cases of recombination events leading to capsular switching among sequence type (ST) 1 group B Streptococcus strains. These strains otherwise shared a common genome backbone with serotype V ST1 strains. However, the genomes of ST1 serotype V strains and those of serotypes VI, VII,...

Sumario:We report several cases of recombination events leading to capsular switching among sequence type (ST) 1 group B Streptococcus strains. These strains otherwise shared a common genome backbone with serotype V ST1 strains. However, the genomes of ST1 serotype V strains and those of serotypes VI, VII, and VIII strains differed substantially.
