“GBS is a transient bacteria which means that a woman could test negative, but be colonized later in pregnancy and vice versa.  GBS is a leading cause of sepsis and meningitis in newborns according to the U.S Centers for Disease Control and Prevention (CDC).  About 1 in 4 pregnant women “carry” or are “colonized” with group B strep.”.
