Group B Strep Infection: GBS | Pregnancy
Group B Streptococcus (GBS) is a type of bacterial infection that can be found in a pregnant woman’s vagina or rectum. This bacteria is normally found in the vagina and/or rectum of about 25% of all healthy, adult women. Women who test positive for GBS are said to be colonized. A mother can pass GBS to her baby during delivery.
