From beginning to end, hear our story! She truly is a blessing, and a miracle given to us by the Lord above.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 lower intestine of 15% to 40% of all healthy, adult women.Those women who test positive for GBS are said to be colonized. A mother can pass GBS to her baby during delivery. GBS is responsible for affecting about 1 in every 2,000 babies in the United States. Not every baby who is born to a mother who tests positive for GBS will become ill.Although GBS is rare in pregnant women, the outcome can be severe, and therefore physicians include testing as a routine part of prenatal care.
