Home is where the host is: evolutionary history of geographic spread, host switching and adaptive genomic signatures in two generalist group B Streptococcus clonal groups

Abstract excerpt

Group B Streptococcus (GBS) is a pathogen of global relevance in neonatal and maternal disease as well as bovine mastitis. Two closely related clonal groups, denoted 103 and 314 (CG103/314), have been detected in humans and cattle on multiple continents in recent decades but are poorly characterized compared to other host-generalist clades. We examined their potential origins, host-switching events and the...
