Group B strep (GBS) is a transient pathogenic bacterium sporadically present in the gastrointestinal tract and reproductive system. Typically, these microscopic life forms do not cause any harm, yet have the potential to present problems for pregnant women and their growing babies.
If you test positive for GBS infection it may mean you are a group B strep carrier rather than a definitive indication that your baby will become ill. Often, it is the babies that are born to moms with large amounts of GBS who are at the greatest risk of becoming infected.
