Group B streptococcus. a type of bacteria that can live in a woman’s vagina and anus without causing an infection. With the exception of a GBS urinary tract infection, most women with GBS present are “carriers†and do not have any signs of an infection. A pregnant woman can pass GBS to her baby during pregnancy or delivery. In a newborn, GBS can cause mild to very serious infection. Because of this, most pregnant women are screened for GBS at 35-37 weeks gestation. Women who are positive for GBS are given antibiotics in labor to prevent infection in the baby after birth.
