This track will present the latest research in group B streptococcus pathogenesis, epidemiology, and therapeutic interventions from early-career investigators.  

Topics include:

1. Characterization of GBS regulatory systems and novel virulence mechanisms in various host environments such as the brain, gut, vagina, and skin  

2. Molecular attributes of GBS clinical maternal and neonatal isolates 

3. Impacts of antibiotic prophylaxis and probiotic treatments on GBS and the host microbiota
